Ubuntu Technologies Plc

Question: ExplainUbuntu Technologies Plc. Answer: Presentation Ubuntu Technologies Plc is a Midlands based association, working for as long as 20 years. The organization has spent significant time in assembling an uncommon kind of adaptable engine motor part. At first, Ross-Royce motors utilized this part. Be that as it may, throughout the years the customer base of Ubuntu upgraded and it included huge automakers, for example, Toyota, Ford, Honda and Mercedes. Some time ago, the business exercises of Ubuntu Technologies Plc were restricted to United Kingdom and some different pieces of Europe. Directly, the market of Ubuntu has extended in different pieces of India, China, Japan and North America. In the previous decade the deals of Ubuntu outside the European market has been expanding while it is declining in the European market. In the post worldwide budgetary emergency period, the organization has experienced troublesome circumstance. As a matter of fact, the whole, engine producing industry has endured in that period. The effect of worldwide budgetary emergency was serious in the USA, EU and UK. The customary market of the organization consequently declined and Ubuntu confronted significant difficulties. Thus, the organization has concentrated on investigating the developing markets of Asia. In any case, the organization don't have sufficient information in regards to the Asian markets. Furthermore, it has been seen that the developing markets are profoundly serious and infiltrating those business sectors will require successful methodologies and satisfactory information. Because of expanded rivalry and some different variables the organization has experienced a misfortune in the last money related year. In this circumstance, the board individuals from the organization are a lot of worried about the future possibility and they have been searching for different alternatives. It has been seen that a leading body of chief of Ubuntu masterminded a gathering for investigating the chance of procuring the by and large of the association. In spite of the fact that some top managerial staff are eager to auction the organization the overseeing chief is cheerful about the drawn out thriving of the organization (Klemstine and Maher, 2014). The overseeing heading of the association has been getting ready to speak to certain systems that would help in restoring the money related situation of the organization. This paper will concentrate on examining the money related situation of the organization alongside evaluating the estimation of the association. Examination of the Performance and Financial Position Ubuntu Technologies have been experiencing a few issues and it is essential to investigate its exhibition and present monetary situation for settling on reasonable choice. Money related execution investigation centers around thinking about the budgetary data of the organization and dissects its exhibition in the course of recent years. Investigation of the money related execution gives an understanding to the significant shortcomings just as qualities of the organization. The aftereffects of the budgetary exhibition investigation will recognize the shortcoming of the association and the organization can concentrate on beating those issues so as to amplify the presentation of the organization. Then again, the significant qualities of the organization can be perceived which will be useful in keeping up the situation of the organization. So as to examine the budgetary presentation, proportion investigation can be utilized for breaking down different execution parts of Ubuntu. This exami nation will be useful for the governing body of the organization for settling on levelheaded choice based on past execution investigation. This segment will incorporate proportion investigation for breaking down the budgetary exhibition of the firm in the course of the most recent three years. Proportion Analysis Proportion investigation is a valuable instrument for breaking down the money related execution of an association. It considers the significant and important budgetary data of the organization so as to figure some money related execution markers (Oliver and Horngren, 2010). Fiscal summaries, for example, accounting report, pay articulation and monetary record are considered for social event pertinent data which will be utilized so as to ascertain different execution pointers or money related proportions. This viable also has been widely considered by different associations so as to investigate the money related execution of the organization. Proportions are considered by the inward just as outside clients of the organizations for settling on choice (Epstein and Lee, 2014). Diverse sort of proportions, for example, productivity proportion, proficiency proportion, liquidity proportion and so on helps in getting an understanding with respect to authoritative execution (Garrison, Noreen and Brewer, 2010). Benefit proportion gives an outline of the capability of the association in making benefits comparable to income. Then again, liquidity proportions gauge the transient money position of the business firm. Effectiveness proportion helps in understanding the proficiency level of the authoritative exercises. Financial specialists proportions are generally considered by the speculators so as to survey the arrival on interest in this association. In this segment, significant budgetary proportions of Ubuntu Technologies Plc have been determined for three back to back years 2012, 2013 and 2014. Gainfulness Ratio Gainfulness proportions help in estimation of the benefit age limit of the organization. Net revenue is determined for showing how much cash is accessible to the organization in the wake of deducting the expense of merchandise sold (Klemstine and Maher, 2014). There are two significant productivity proportions that will be determined in this segment: net overall revenue and net revenue. Net revenue evaluates the proportion of the income to the sum left in the wake of considering the expense of merchandise sold. From the accompanying table, it tends to be discovered that the gross net revenue of the organization has declined in the course of recent years. It very well may be discovered that the expense of products sold is expanding however the income isn't expanding in a similar extent (Oliver and Horngren, 2010). It doesn't have a positive sign for the budgetary strength of the association. It very well may be expressed that the promoting techniques have not been powerful in upgradin g the income of the association. Then again, net overall revenue is determined in the wake of thinking about the all out use of the organization (Horngren, Harrison and Oliver, 2009). It is determined by the proportion of income of that association for that budgetary year to the sum left in the wake of costing all the costs of that firm (Peterson Drake and Fabozzi, 2006). If there should arise an occurrence of Ubuntu, the net overall revenue of the organization has been seen as negative in 2014. It began declining since 2012 and in 2014, the organization experienced loss of 3.87%. It doesn't demonstrate an ideal money related situation of the organization (Garrison, Noreen and Brewer, 2010). The uses of the organization have expanded altogether. Be that as it may, the business income has not expanded in a similar extent. Thus, it tends to be unmistakably inferred that Ubuntu Technologies have not had the option to create reliable benefit over the three monetary years (Kieso, Weygand t and Warfield, 2012). (*values are in millions) 2014 2013 2012 Productivity Ratio Net Profit 115.00 125.00 135.00 Income 630.00 610.00 580.00 Net Profit Margin 18.25% 20.49% 23.28% Net Profit - 24.40 5.00 12.00 Income 630.00 610.00 580.00 Net Profit Margin - 3.87% 0.82% 2.07% (Source: (Peterson Drake and Fabozzi, 2006)) Liquidity Ratio Liquidity proportions are significant for understanding the momentary liquidity of the firm (Seal, Garrison and Noreen, 2009). It essentially centers around evaluating the money position of the organization so as to meet the commitment that is present moment (Wernz, 2014). Liquidity proportion helps in surveying whether the organization can possibly direct its everyday operational exercises. Current proportion and speedy proportion are viewed as two significant proportions for assessing the dissolvability of an association. Liquidity proportions think about the transient resources and momentary liabilities structure the monetary record so as to decide the transient money position of that business firm. Current proportion is the extent of short terms resources and transient liabilities of the organization. On the off chance that the proportion is more prominent than 1, it shows the organization can possibly meet the momentary commitments with the guide of its present resources. Conversely, if the current proportion is under 1, it suggests the business firm doesn't have satisfactory current resource for meeting the momentary liabilities of the firm. The organization needs to orchestrate momentary resources, for example, money, bank parity, stock, and records receivable for keep up moderate degree of current resource which can be adequate for meeting the prerequisite of the organization. The liquidity position of Ubuntu has declined over the period and in 2014 the current proportion is under 1. In 2012, current proportion was 1.15 which shows the organization had sufficient current resource that helps in meeting the transient commitment of the organization. Be that as it may, the curr ent proportion declined in the back to back two money related years: 2013 and 2014. It demonstrates an ominous situation for the organization. Speedy proportion is another significant liquidity proportion that helps in evaluating the momentary money position of the association. Speedy proportion doesn't consider inventories as current resource as it can't be changed over to money rapidly (Kieso, Weygandt and Warfield, 2012). The snappy proportion of Ubuntu has declined over the three years and it is extremely poor in 2014. It implies the organization has been battling to meet its momentary liabilities in the previous three budgetary years. In addition, it very well may be inferred that the stock of the organization is fundamentally high and when it isn't considered in the current resource, the liquidity proportion declined forcefully. 2014 2013 2012 Liquidity Ratio Current Asset

The Great Depression

The Great Depression Free Online Research Papers The Great Depression was a period in history that nobody will ever overlook or get the opportunity to not find out about it. This period is discussed in history classes the world over on the grounds that it transformed into a worldwide bad dream.

The Legalization of Prostitution - Free Essay Example

Prostitution has been a highly controversial topic for hundreds of years, the majority of those who work in this business being female, while the majority of the patrons are male. Though it has been controversial, it is illegal in most places and has been for a long time. It being illegal is infringing on the privacy of those giving or receiving this service. Prostitution should be treated as if you are getting a haircut. For those who want to make extra money, why shouldnt they be able to do as they wish with their bodies? Many argue that legalizing prostitution would cause sex trafficking to increase, which is untrue. Overall, legalizing it would make for a freer society. Prostitution being legal would make it much safer, decrease sex trafficking, and increase the availability of health care. As it is now, prostitution is very dangerous. Making it legal would take away some of the risk that comes with being in this business. Not only would it allow for the women in brothels to be given more of the money they earn, but allow them protection. For example, in New Zealand, prostitution was made legal in 2003. Following this change, brothels have popped up near many normal bars and hang out spots. According to some of the women who worked before and after this change, police officers are now much more readily available to help the women in the business and ensure they are safe (Glazer 342). This also allows the prostitutes to feel more comfortable reporting abusive clients and pimps, providing protection against physical harm. Not only that, but it would allow it to be a freer business. The women working in the brothels would be able to decline customers for any reason, as well as being able to leave a brothel at their own will. It is very common for prostitutes to avoid or feel unable to get health care, something crucial to people in this business. If it were legalized these women would feel much more comfortable not only seeking medical care, but opening up a dialogue with their doctors about concerns and preventative care. For example, for a short time in the 2000s prostitution was legalized in Rhode Island. There was a 39% drop in female gonorrhea, which was believed to be caused by the power of the prostitutes to insist on condom use. Not only will it allow these women to come forward and feel comfortable getting healthcare, but will make brothels be considered serious, licensed businesses, giving their employees benefits such as health insurance. In the brothels in Nevada, the employees are regularly screened for HIV as well as clients being screened before coming in (Ivie 56). For the way that prostitution is currently regarded in laws, there is a large double standard based on gender. In most states, the prostitute, usually a woman, is considered unneeded and disposable, receiving much harsher punishment than their male clients who receive little to no punishment. In Kentucky, men cannot be convicted of prostitution according to their laws, showing a huge gender bias, making it impossible to punish men for the same act that women do. Not only that, but convicted prostitutes must complete HIV testing, while patrons do not (Cooke and Sontag 474-75). Overall, there is not equal punishment for those who provide the service and those who purchase it. Legalizing prostitution has many benefits. Many people have false deceptions about what would happen if it was legalized. For example, many think that it would increase trafficking, enabling the people who do this. In reality, it would decrease trafficking, shedding light on the topic and forcing the women who are prostitutes to be registered with an official business. Overall, it would be a positive thing to legalize it, allowing for a freer society through less trafficking and more privacy for what women are allowed to do with their bodies, increasing the availability of health care to these women, and allowing for safer interactions in this business.

Essay On The Death Penalty - 1641 Words

The death penalty plays a controversial role in modern society. Many arguments against the death penalty are raised to question whether it is biased against race or violates the constitution. Reuben Greenberg, the first black police chief involved in innovative criminology and author of the article â€Å"Race, the Criminal Justice System, and Community-Oriented Policing,† openly shares his opinion on how race does not affect the death penalty. Reuben Greenberg also proves false accusations of the death penalty wrong. Jack Greenberg, American attorney and author of Against the American System of Capital Punishment,† disagrees with Reuben Greenbergs statement, and claims that race does hold a high position within the death penalty. Aside from†¦show more content†¦Along with this, Reuben Greenberg believes that you have to look past a persons skin color and judge them on their crime, not their looks. Haag agrees with Reuben Greenbergs statement on how people should nt judge someone just because of their race. The subject of race can become very biased, and many people feel as if the justice system can be racist towards minorities. In my opinion, race should not play a role in death penalty. Although there are still many racist people in the world, crimes should be prosecuted based on the crime committed, regardless of the person’s race. Many white people are on death row currently for the same crimes a minority might commit. In the world today, many controversial events have happened dealing with race along with the justice system. For example, there have been multiple incidents where a white officer has been charged with shooting a black person. It is thought that if a white judge is sentencing a minority, the odds of the minority getting put on death row would be in favor. A judge must have an opinion when it comes to sentencing a criminal, but it does not always have to be the â€Å"race card†. The severity of the crime should be the real reason as to why a person would b e put on death row, not their skin color. If a minority commits a crime worthy of the death sentence, the judge has the right to sentence that upon him, regardless of looking at his skin.Show MoreRelatedThe Death Penalty Essay610 Words   |  3 PagesThe Death Penalty The Death penalty has been a controversial subject since the beginning of time.

Social Services: group home attendant, case worker, probation officer, admissions counselor, occupational therapist, substance abuse counselor, youth counselor, employment counselor, social service aide, public health administrator, parole officer, social-urban planner, community relations officer, affirmative action officer, vocational rehabilitation, and day care center supervisor. What Psychologists Do Psychologists study the human mind and human behavior. Research psychologists investigate the physical, cognitive, emotional, or social aspects of human behavior. Psychologists in applied fields provide mental health care in hospitals, clinics, schools, or private settings. Like other social scientists, psychologists formulate hypotheses and collect data to test their validity. Research methods may vary depending on the topic under study. Psychologists sometimes gather information through controlled laboratory experiments, as well as through administering personality, performance, aptitude, and intelligence tests. Other methods include observation, interviews, questionnaires, clinical studies, and surveys. Health psychologists promote good health through health maintenance counseling programs that are designed to help people achieve goals such as to stop smoking or lose weight. Cognitive psychologists deal with money, thinking, and perceptions. Some conduct research related to computer programming and artificial intelligence. Counseling psychologists use various techniques, including interviewing and testing to advise, on how to deal with problems of everyday living. Developmental psychologists study the physiological development that takes place throughout life. Experimental or research psychologists work in university and private research centers, and in business, nonprofit and governmental organizations.

How to Write an Extended Essay

How to Write an Extended Essay How to Write an Extended Essay In the following article we will give you some valuable advice on how to write a good extended essay. We will offer you just some useful tips and simple information here. The extended essay is actually a mini-diploma work which IB students have to write, besides several other papers. It has the same goals, basic structure, and context like the diploma theses which college students prepare. You must do your own piece of research, although it is usually stated that the extended essay does not constitute any type of research. In all cases, you conduct your investigation according to the criteria stipulated by the academic community: clear thesis, strong arguments and evidential support, comprehensible and concise work, loyalty to the facts, work with sources, and last but not least, fruitful collaboration with the assigned supervisor. The extended essay may be focused on a topic derived from every possible field of science, culture, and arts, so you should accommodate your work accordingly. For example, a work in the field of natural sciences may require conducting experiments; on the other hand, in the field of Philosophy you should work with philosophical theories. However, you must demonstrate some definite skills and competences. Writing an extended essay – important tips Define your topic You can choose your topic from a list. Try to narrow it down in order to be easier for you to set forth the main thesis. Wider topics are more difficult to be justified. Try to focus your efforts on a particular place, time, concept, or case. Preliminary research Find some sources on the topic and after that modify your topic and thesis accordingly. Work with academic literature, and be critical to the information available on the internet. You can search in Google Scholar or Google Books. Now you can write a draft of the extended essay. Structure The structure of your essay is strictly set according to the academic standards. You should write several parts: a title page, an abstract, body text, a conclusion, a bibliography, and (not necessary) appendice/s. You may use footnotes or endnotes, and also it would be good to prepare a glossary of the terms used (not necessary). The length should not exceed 4,000 words (without the abstract, the bibliography, the endnotes/footnotes and the appendices). Style You have to employ an academic reference style, for instance APA, MLA or Chicago/Turabian style (depending on the field of research). Try to write clearly and to be accurate in using definite terms (that means, you should be familiar with the terms you use). If you are not sure what a term means, don’t use it (replace it with a synonym). The same can be said about quotations: quote only short sentences or passages which you understand and can integrate into the text easily. Be careful: quotes should not exceed 10-15 % of the body text. Otherwise, the examiner would think you do not have anything important to say. Be loyal to the facts That means, never refer to the facts which are not well-proven, or that may support a theory contrary to your thesis. Check your sources. How can you do it? You should simply search for some criticism about the authors you refer to. Then you will be able to discern between the real scientist or researcher, and the pseudo-researcher. Be critical! The supervisor Your supervisor will review your work; he/she will give you some advice on the sources and information you should use. They will also check the draft of your essay and will recommend a way to improve it. Your supervisor is not the one who has to write the extended essay for you. Don’t expect it from them! The interview Although it is not an obligation, but still, it is recommended to have an interview with your supervisor. They will ask you some questions related to the text. The main goal is to check your knowledge in the field as well the authenticity of the work (to check for plagiarism). The extended essay is your first real test of the system of education. It operates as a â€Å"bridge† between the high school and tertiary education. By passing this exam, you will have more opportunities to find a good college.

The Personal and Professional Development of Students Essay

The Personal and Professional Development of Students - Essay Example My decision to appeal is mainly motivated by the fact that it has always been my cherished desire to pursue my higher academic qualifications from the university. The university is renowned for its personalized and excellent academic programs that significantly contribute to the personal and professional development of students. I strongly believe that my consistent high grade of 3.89 GPA in the academic programs and nomination to the Dean’s list would be a vital element in the reconsideration process. Moreover, last fall, I was not able to complete pre-calculus class (Math 43) due to ill health which was probably an important factor in my rejection. The calculus sequence would be completed by the summer, thus fulfilling all major requirements for the transfer. I am a self-driven individual with a passion for learning and tend to use paradoxical thinking to seek an innovative solution to mundane problems. I have actively participated in the Honors Program and Phi Theta Kappa t o push myself to a higher limit and motivate peers. Most importantly, the various modules of the course curricula are designed to provide persons with a strong knowledge-based degree which would facilitate more efficient and accurate decision-making process in the professional field in the area of economics and management. This would considerably complement my basic inquisitive nature and empower me with skills and information that can be applied to current situations and areas within personal and professional lives. I sincerely believe that the degree programs would be the right choice for me and help me realize my dreams and meet the challenges of time with great success.

A Legal, Ethical, Global, and Corporate Environment in Business Research Paper

A Legal, Ethical, Global, and Corporate Environment in Business - Research Paper Example Therefore, she had a prima facie case against her employer because the employer was unable to prove that Tiano’s leave affected the business adversely (Clarkson et.al, 2012). In this case, Meads owned Citibank a credit-card debt amounting to $5,000 of which he could not be able to settle at that moment because of his health issues. He officially informed the creditor about his predicament and together with his attorney they informed the creditor that in future the creditor should contact Meads’ attorney. However, Citicorp who was working as Citibank agent made numerous calls at Meads home and place of work. Meads sued â€Å"CCSI for causing emotional distress.† According to Fair Debt Collection Practices Act, the CCSI did not anything to warrant the charge against unfair debt collection. However, the manner in which they collected the debt would attract a charge against â€Å"cause for distress† because they should have contacted Meads’ attorney considering the health condition of the debtor and directives by the attorney to contact him on behalf of his client (Clarkson et.al, 2012). In this case, Hoffman had entered into an agreement with Red Owl without any consideration. The contract was based on the verbal promise. Hoffman can successfully sue Red owl Stores under the promissory estoppels because the defendant made a promise to the plaintiff and never fulfilled it. In order for Hoffman to succeed in the legal claim, Hoffman should be able to convince the jury that they relied on Red Owl Store’s pledges and that upon the reliance on those promises, they suffered certain adversities. However, Hoffman should be prepared to get compensation for the actual loss suffered. The court may stop the agreement between the plaintiff and the defendant if by continuing with the agreement will result in unfairness between the parties (Clarkson et.al, 2012).   

Critical study of how music uniquely expands our understanding of experience Essay Example for Free

Critical study of how music uniquely expands our understanding of experience Essay Music has long existed in our society as a form of culture, entertainment and the like. In fact every civilization known to exist had had a great deal of benefits from music. There are lots of people who see music as nothing more than plain entertainment however there are those who holds in the claim that music gives us something more than entertainment per se. There are claims that music could affect us in a number of ways. Music has considerable effects on one’s mind, body and emotions. Music that are abundant in beats in a way could fuel one’s body, music carried out with feelings could affect one’s emotional status and could either make one cry with misery or laugh with joy, classical music could stimulate the mind, and so on and so forth. There are people who are greatly aware of the effects music could wrought on a person and this could greatly be seen on our everyday experiences. Movies, films, news, see the importance and know the effects music could have on every individual and thus music is key parts in every movie made nowadays. Have you ever seen a movie that doesn’t have an original sound track or a movie that did not make use of background music? Ever seen a documentary and the like who did not use music in the background while portraying the videos or documents they have? Having seen some of the uses music could have it may now suffice to say that music is indeed an important aspect in our lives and it plays fundamental role in today’s society (as well as on societies which existed thousand of years ago). As was stated music is an essential part of every culture, of every society and thus it is of no surprise that music is seen as a part of our everyday routines. Music could have fundamental effects on one’s emotion. Think of an instance wherein certain music affected you emotionally. Say you heard a certain song and it evoke within you some sort of emotions like pain, happiness and the like. I remember for an instance a conversation I have had with a friend of mine. He always loves to listen to the lyrics of Ever After of Bonnie Bailey and Come Around by Rhett Miller. He told me that he love listening to Ever After because that used to be their theme song (of his ex girlfriend) and he loves singing Come around because he can relate to that particular song. Thus, seemingly music indeed has certain effects on our emotions. I even remember claiming that my friend is such a masochist because he loves listening to sad songs such as Come Around when he has a choice to do otherwise. Similarly music has certain ways of affecting one’s mood. However it is not really known how do music affects a person physiologically and psychologically as well. Thus, a question may arise as to how do certain music affects a person’s mood. In order to determine how music affects a person’s mood one must first know the root as to how music inspires a person’s emotion. There are two contrasting viewpoints who tried to answer this particular puzzle. These views are called emotivist and cognitivist. For an emotivist they believe in the notion that we feel certain emotions as a form of response everytime we hear certain music. The cognitivist on the other hand believes otherwise. The cognitivists believes that there is more to humans than emotions and thus they believe that we get to decode certain musical emotions on a rational level, thus it shows that the cognitivists do not really believe that we really get to experience musical emotions. In order to see whether the beliefs of the emotivists are correct or not an experiment needs to be conducted in order to see if there are certain music models which could draw out coherent physiological reactions from different kinds of people. This experiment is needed in order for us to see if we really do experience emotions when exposed to a particular music. It is in this regard that a study had been conducted by Krumhansl wherein two groups of student were used. These particular groups of students each partake different activities. The activity went as follow: One group of 40 students dynamically rated the levels of sadness, fear, happiness, and tension in six sample pieces intended to evoke sadness, fear, or happiness. They did so by adjusting a slider on a computer while the music was playing. A separate group, consisting of 38 college students, was hooked up to physiological sensors monitoring a variety of cardiovascular, electrodermal, and respiratory responses which recorded their change over time. Both groups heard the six musical samples with a 90-second pause in between each. The physiological measures taken from the second group were compared with the degree of sadness, fear, happiness, and tension reported by the first group. Both the physiological measures and emotional ratings were recorded as they changed during the course of the piece. Therefore, correlations could be drawn between the intensity of certain emotions and physiological symptoms. (Boswell) The results shown by the experiment was in accordance to the side of the emotivists. Each of the musical selections was rated as having the intended emotion, and consistent physiological responses were found for each measured emotion: sad music was correlated with a decreased heart rate, lowered finger temperature, increased blood pressure, and decreased skin conductance level; happy music with faster and shallower breathing, and fear-invoking music with a slower pulse, faster breathing, and decreased finger temperature. These effects were consistent during the duration of the pieces. (Boswell) This is further proof that the emotivists position was indeed supported by the said experiment. The fact that there was a coherent physiological modification that was produced by the different music used in the said experiment were behavioral evidence enough that those college students indeed experienced certain emotions all throughout the time they were exposed to the music used. This result contradicted the claim that emotions could only be transmitted once a person gets to recognize a certain passage present within a particular music. Another study was made by Sloboda. Sloboda attempted to identify the exact musical composition which brings about definite physical emotional responses. Examples of the said responses are tears, trembling, and the like. The study made use of questionnaire which was dispersed to five hundred British citizens. However, only eighty-three persons send back the survey. It is an important thing to know that those eighty-three persons who answered the survey were experts in terms of music, particularly classical music. The said survey had went on as follow: Participants were instructed to indicate the frequency with which they experienced certain physical responses as an effect of music within the last five years, as well as the piece of music and, if possible, the specific part of the piece or musical event that provoked it. In addition, they were asked to say whether the response was consistently evoked. (Boswell) A huge number of the partakers claimed that they were able to experience certain physical emotional responses such as mirth, trembling, tears, lump in their throats and the like for the last five years of their lives. However the survey showed that women are more prone to experiencing tears as compared to men. Men on the other hand, especially those already on their thirties, claimed that they experienced more laughter than compared to other age. Just as was the case on the experiment conducted by Krumhansl, the survey conducted by Sloboda also showed a great deal of consistency to each piece of music they were exposed to. This particular survey also showed the extent of the consistency in that the reactions remained consistent even though they have heard the certain musical piece for more than fifty times. A further point of interest is that there are particular melodic constructions which showed to have consistent effects upon the partakers of the said survey. Appogiaturas for one were consistent in bringing tears into surface. The experiment also showed that a series of changes in terms of harmony incite trembling, whereas quickening brought about faster heart beats. However, if there is a certain drawback in the said study is the fact that it was conducted with the use of questionnaires. We could have no way of knowing if the person who answered it had answered truthfully or if s/he is merely bluffing. Thus, in a way we have no way of making sure that the partakers of the said survey indeed experienced the particular emotions and physical responses they reported they have experienced for the past five years. Another factor is the fact that those who participated in the survey were all expert on the field of music and thus we could not really deduct from this survey alone that the rest of the world would also act or feel the same way. However there are certain studies which had been conducted which show that very little difference exists between those who have musical expertise and those who have none. In addition, the records stated by the partakers of the said survey regarding their experiences of physical signs of emotions are not really unusual. Thus, in a way we could say that the study conducted by Sloboda also supported the position held by the emotivists. We should also take into account the fact that the physical responses reported by the survey partakers are in fact common in all human beings since we all share the same autonomic response system. However, we should also take note of the fact that our capability to utilize the said system in order for us to feel or experience certain emotions brought about by music is in a way, a learned process. This particular claim is supported by the fact that very young children do not really get to experience the said responses. Even those adults who have different kinds of music as compared to ours are not likely capable to experience the said responses brought about by the music we listen into. Thus, Sloboda claimed that the link between musical compositions and emotions is a learned process which is also dependent on one’s culture. However, this does not necessitate that we do not really get to experience or fell certain emotions from listening to certain music. It only tells us that we may not be able to relate nor are we likely to experience certain emotions from listening to other music that are completely different from ours. Fact is, Sloboda even claimed that if we are to be exposed to music completely different from ours we could still get to relate to that music although it would take time. Therefore even though the link between musical compositions and emotions is a learned process, evidences and studies still show the stand held by the emotivists that we are indeed capable of feeling or experiencing certain emotions simply by listening to a particular music. Thus those who participated in the studies conducted have steadily testified that they have indeed experienced true emotions when they listened to certain music. The researches conducted also accounted for the fact that very little difference in terms of recognizing emotions could be seen between those who have musical expertise and those who have none. Thus this accounted for the emotivists view that we could indeed experience certain emotions simply by listening to certain music, although it is still not clear what inclines us to be affected in certain ways. Research conducted claims that there is really no ground in saying that somewhere in our brains there could be located a region dedicated mainly to process musical data. In contrary, the errand of musical processing is extended to the whole region of our brains. Thus whereas the right brain is responsible for the emotions evoked while listening to music, the left brain is quite responsible for looking at music in a more rational ground thus it tends to critically examine music. There are even proofs which show that the primeval region within our mid brain is the one responsible for our emotions we experience while listening to music. Thus a primeval region within our midbrain engages itself with the task of realizing and appreciating music in an emotional way. However, the specific region wherein music is being developed (if ever there is one) is yet to be known. A study which involves this particular interest was conducted by Schmidt and Trainor. Schmidt and Trainor studied whether or not frontal brain electrical activity correlated with intensity and positivity or negativity, or valence, of emotion. The study showed that the left frontal brain is the one responsible for experiencing positive emotions whereas the right frontal brain is the one responsible for experiencing negative emotions. Thus, emotions such as happiness, interests and the like are product of the left frontal brain whereas emotions such as horror, revulsion, pain and the like were made by the right frontal brain. Therefore it would suffice for us to say that when listening to happy tunes our left frontal brain is likely to be triggered whereas listening to desolate songs would trigger our right frontal brain. It also follows that the intensity of music could affect the intensity of the frontal activity. The hypothesis stated above had already been confirmed. A careful selection of music which would likely draw out positive emotions triggered the left frontal brain whereas a careful selection of music which would likely draw negative emotions triggered the right frontal brain. Thus, the frontal activity of the brain increases every time the intensity of certain music also increases. Thus in a way this is also another proof which supports the emotivist view that listening to certain music could make a person experience certain emotions. Thus a similarity between music and language could be seen. Both language and music alike is inclined to be interpreted subconsciously. Thus, this seems to show that humans have a biological structure which enables music to draw emotions from each of us. And though this particular structure is yet to be known, researchers concluded that the said structure is not composed of a single area on the brain. On the contrary, researchers believe that such structure is made up of an interaction of the different systems which could be found within our brain. It is due to music’s many uses that music is also deemed to have considerable effects on the field of medicine. There are certain accounts taken from the Bible, artifacts, as well as studies that show that music could have considerable effects on a person’s health and well-being. In fact, there are historical inscriptions taken from Egypt, Greek, China and other known civilizations which praise music’s ability in medical matters. Music is widely considered to have medical importance and it is in this regard that music even such a term such as music therapy. After World War II the United States of America even see to it that music therapy would be used on wounded soldiers who were tormented by physical as well as emotional traumas taken from the war. Physicians and nurses alike saw how music helped alleviate some of the soldiers or veterans pain by merely engaging themselves on musical activities. It is on this regard that hospitals started employing musicians to help better their patients’ status. Music had been very helpful in bettering the patient’s emotional as well as psychological status and as many people learned of these certain benefits derived from music, National Association for Musical Therapy came to existence. The need for musical therapy became wide range to the point that the National Association for Musical Therapy or NAMT allied themselves to other musical organizations which in turn resulted into the foundation of the American Music Therapy Association or AMTA. The ranges of music therapy vary widely in that it not only caters to emotional sickness since it also proved to be beneficial in sickness suffered under physical injuries. Music therapy helped people in terms of their perceiving pains. There are a number of reasons why they consider music as an effectual means in limiting perceived pains. First, music could divert a person’s mind from the pain at hand or from the pain a person perceives. Second, music could help in terms of giving a person some kind of control. Thirdly, music could help counter pain since it could help a person in releasing endorphins which are necessary in giving a person some sense of well-being. Fourth, slow music could help a person in terms of relaxation in that it slows a person’s breathing. Take a person with leukemia for an example. Let’s say Person A needs to undergo a certain surgery necessary to cure his leukemia. One should admit that surgical procedures are indeed frightening and thus Person A could not help but be afraid of what’s on store for him and thus Person A’s blood pressure continues to rise and this in turn has a crucial effect on Person A’s healing process. This particular thing could also heighten Person A’s awareness or perception of pain. One’s pain could not be measure by anyone and thus there is no standard in terms of the amount of pain a person could have. It is in this manner that music therapy comes into the picture. We have already enumerated the reasons why music therapy is considered beneficial in medicine and thus in this manner one could be lead to speculate that music therapy could indeed lessen one’s pain perception because it could work in certain ways in order to lessen a person’s perceived pain. Disturbance or diversion could help in certain ways in lessening one’s sense perception and thus it could help moderate the pain a person undergoes. This pain moderation could be redirected to the cognitive section which could be seen in the Gate-Control Theory of Pain. Pleasant music naturally applies or concentrates on a person’s pleasant stimulus which in turn concerns the capability of the information processing system. Since the music would be busy attending to the pleasant stimulus of a person it naturally follows that the person’s occupation would be diverted from the pain-causing stimulus. It is ion this regard that music is considered important in distracting a person because distraction presents a person with an escape by means of imagination which in turn is a crucial means in lessening stress, nervousness and fear which are important factors which constitutes pain. Thus enjoyable imagination could promote some sense of control to a person which could decrease a person’s nervousness and feeling of being powerless. Thus since music helps transfer our attention away from painful experiences it provides us with a strategy we could use when we undergo painful experiences, may it be physically or emotionally.

How the Computer Works :: Personal Computers PC

Many people assume that computer are difficult to understand and difficult to use; however, the first step is understanding and learning to use the computer. The types of hardware that all computer systems use and the types of software that make them run. Like millions of computer users, microcomputers where used to play games, explore the Internet, write papers, build spreadsheets, or create a professional-looking proposal or flyer. You can perform all these application without understanding exactly what goes on behind your computer case or monitor screen. We the computer user, turn on the machine, load software program, and use that software to accomplish a task without knowing what goes on behind the scenes or the basic functions of the computer components. It is also important to know how to protect the computer. The complete computer system consists of four parts; hardware, software, people, and data. The term hardware refers to the physical components of the computer, such as the monitor, keyboard, memory chips, and hard drive. The term software refers to the set of instructions that directs the hardware to accomplish a task. People are the customer operators, known as users. Data consists of raw facts, which the computer stores and reads in from of numbers. In order to perform a computing task, hardware is used by software for four basic functions: input, processing, output and storage. The computer user interacts with a computer in a language that the user understands, but software must convert that instruction into a form that hardware can understand. Hardware stores data and communicates with software by only one fundamental method--binary--and, in effect, speaks a language that only has two words, "on" and "off." All communication, storage, and processing of data inside a computer are in binary until presented as output to the user. The binary number system, is the language of the computer. The central, most important hardware device in a computer is the central processing unit (CPU) or microprocessor. Date received by input devices goes to the CPU, and output travels form the CPU to output devices. The CPU stores data and instructions in storage devices and performs calculations and other processing of data as well. A method for the CPU to communicate with the device will need to send data to and/or receive data from the CPU.

10 A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY Alan Januszewski h e State University of New York at Potsdam Kay A. Persichitte University of Wyoming Introduction The purpose of this chapter is to provide a historical context for the current dei nition of educational technology. We will do this in several stages. First, we will review the primary purposes and considerations for dei ning educational technology. h en, we will review each of the four previous dei nitions, paying particular attention to the primary concepts included in each dei nition.We will examine the context and rationales for decisions made regarding each of these primary concepts. We will also present some of the historical criticisms of the dei nitions which provided the impetus for changing the dei nitions. h e criteria and purposes for producing a dei nition were discussed at the time of the writing of the i rst dei nition in 1963. A satisfactory dei nition of instructional technology wil l let us i nd common ground, will propose tomorrow’s horizons, and will allow for a variety of patterns that specii c individuals may follow in specii c institutions . . Research must be designed in terms of clear understanding of instructional technology.

Teacher-education institutions need assistance in planning courses for pre-service and in-service instruction that will provide the skills and understanding which will be required in tomorrow’s classrooms . . Let us consider the criteria for useful dei nitions. h ey should (a) clarify the description of the i eld in ordinary language; (b) summarize existing knowledge; (c) mediate applications of knowledge to new situations; and (d) lead to fruitful lines of experimental inquiry. . . . h is report aims to provide a working dei nition for the i eld of instructional technology which will serve as a framework for future developments and lead to an improvement in instruction. (Ely, 1963, pp. –8) h ose involved in the writing of the 1963 dei nition obviously believed that there were a lot of things to consider when dei ning educational technology. Or put dif erently, the existence of such a dei nition would have far reaching consequences, sometimes with implications that the authors might not intend. Acknowledging this opened the door to criticisms of the dei – nitions and the purposes cited for redei ning educational technology. h e authors of subsequent dei nitions all seemed to adhere, at least in part, to the purposes and criteria identii ed in the 1963 dei nition.The 1963 Definition h e leadership of the Association for Educational Communications and Technology (AECT) recognized the 1963 dei nition of audiovisual communications as the i rst formal dei nition of educational technology (AECT, 1977). h is dei nition, the i rst in a series of four oi cially sanctioned dei nitions, was developed by the Commission on Dei nition and Terminology of the Department of Audiovisual Instruction (DAVI) of the National Education Association (NEA) and supported by the Technological Development Project (TDP).In 1963 audiovisual communications was the label that was used to describe the i eld as it was evolving from the audiovisual education movement to educational technology: Audiovisual communications is that branch of educational theory and practice primarily concerned with the design and use of messages which control the learning process. It undertakes: (a) the study of the unique and relative strengths and weaknesses of both pictorial and nonrepresentational messages which may be employed in the learning process for any purpose; and (b) the structuring and systematizing of messages by men and instruments in an educational environment. es e undertakings ER5861X_C010. indd 260 ER5861X_C010. indd 260 8/16/07 6:24:23 PM 8/16/07 6:24:23 PM10. A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 261 include the planning, production, selection, management, and utilization of both components and entire instructional systems. Its practical goal is the ei cient utilization of every method and medium of communication which can contribute to the development of the learner’s full potential. (Ely, 1963, pp. 18–19) A footnote that was included as part of this dei nition read â€Å"the audiovisual communications label is used at this time as an expedient.Another designation may evolve, and if it does, it should then be substituted† (p. 18). Conceptual Shit s Signaled in Dei nitions h ere are three major conceptual shit s that contributed to the formulation of the dei nitions of educational technology as a theory: (1) the use of a â€Å"process† concept rather than a â€Å"product† concept; (2) the use of the terms messages and media instrumentation rather than materials and machines; and (3) the introduction of certain elements of learning theory and communication theory (Ely, 1963, p. 19).Understanding these three ideas and their impact on each other is essential to understanding the idea of educational technology in 1963. A technological conception of the audiovisual i eld called for an emphasis on process, making the traditional product concept of the i eld of educational technology untenable. h e Commission believed, â€Å"h e traditional product concept in the audiovisual i eld views the ‘things’ of the i eld by identifying machines, use of particular senses, and characteristics of materials by degrees of abstractness and/or concreteness† (Ely, 1963, p. 19).Members of the Commission preferred a process concept of the i eld which included â€Å"the planning, production, selection, management, and utilization of both components and ent ire instructional systems† (p. 19). h is process conception also emphasized â€Å"the relationship between events as dynamic and continuous† (p. 19). h e Commission argued that â€Å"materials† and â€Å"machines† were â€Å"things† or products and opted not to use those terms in the dei nition. Instead, the Commission used the terms messages and instruments. h e Commission further argued that materials and machines were interdependent elements. A motion picture and projector are inseparable as are all other materials requiring machines for their use† (Ely, 1963, p. 19). One was of little practical use without the other. h e Commission used the concept of media instrumentation to explain instruments. h e Commission said, â€Å"Media-instrumentation indicates the ER5861X_C010. indd 261 ER5861X_C010. indd 261 8/16/07 6:24:23 PM 8/16/07 6:24:23 PM262 JANUSZEWSKI AND PERSICHITTE transmission systems, the materials and devices available to carry s elected messages† (Ely, 1963, p. 20). e concept of media instrumentation also included the people who utilized the instruments in the educational environment as well as the transmission systems. h e idea that both people and instruments comprised media instrumentation was based in the broader concept of the man-machine system (Finn, 1957). In discussions of the relationship and integration of learning theory and communications theory to instructional technology, the Commission stated, â€Å"Certain elements of learning theory and communications theory of er potential contributions [to the i eld of educational technology]; e. . , source, message, channel, receiver, ef ects, stimulus, organism, response† (Ely, 1963, p. 20). h e Commission integrated learning theory and communications theory by identifying and combining the two systems basic to the process view of the i eld: the learning-communicant system and the educational-communicant system. h ese two systems use conce pts from both learning and communications theories that delineated and specii ed the roles of the individuals involved in the use of these systems. e learnercommunicant system â€Å"refers to the student population† and the educationalcommunicant system â€Å"refers to the professional persons in the school† (p. 23). h ese two systems could be of any size, ranging from a single classroom to large school systems (Ely, 1963). Merging the two communicant systems into a single model of the educational process provided the i eld of audiovisual communications with a theoretical framework (Ely, 1963) and a model that allowed educational technology to be viewed as a theoretical construct (AECT, 1977). e fundamental doctrine advanced by the writers of the i rst dei nition was that it was a â€Å"branch of educational theory and practice. † h e word theory was particularly important in this dei nition because it had a special place in the history of the audiovisual i eld, because of the status that it conferred on the i eld, and because of the expectation for further research to inl uence the evolution of that theory. Finn’s Characteristics of a Profession e 1963 dei nition was heavily inl uenced by James Finn’s (1953) six characteristics of a profession: (a) An intellectual technique, (b) an application of that technique to the practical af airs of man, (c) a period of long training necessary before entering into the profession, (d) an association of the members of the profession into a closely knit group with a high quality of communication ER5861X_C010. indd 262 ER5861X_C010. indd 262 8/16/07 6:24:24 PM 8/16/07 6:24:24 PM10.A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 263 between members, (e) a series of standards and a statement of ethics which is enforced, and (f) an organized body of intellectual theory constantly expanded by research. (p. 7) Of these six characteristics of a profession, Finn (1953) argued that â€Å"the most fundamental and most important characteristic of a profession is that the skills involved are founded upon a body of intellectual theory and research† (p. 8). Having established the importance of theory and research for a profession, Finn further explained his position by saying that â€Å". . this systematic theory is constantly being expanded by research and thinking within the profession† (p. 8). Finn was arguing that a profession conducts its own research and theory development to complement the research and theory development that it adapts/adopts from other academic areas. If educational technology was to be a true profession, it would have to conduct its own research and develop and its own theory rather than borrowing from more established disciplines like psychology.Finn (1953) evaluated the audiovisual i eld against each of the six characteristics and determined that the audiovisual i eld did not meet the most fundamental characteristic: an organized body of intellectual theory and research. â€Å"When the audiovisual i eld is measured against this characteristic . . . the conclusion must be reached that professional status has not been attained† (Finn, 1953, p. 13). h is argument was largely accepted by, and had a profound ef ect on, the leadership of the audiovisual i eld in the late 1950s and early 1960s.Finn (1953) laid a foundation that the audiovisual i eld was troubled by a â€Å"lack of theoretical direction† (p. 14). He attributed this to a â€Å"lack of content† and the absence of â€Å"intellectual meat† (p. 14) in the contemporary meetings and professional journals of the i eld. In his argument promoting the development of a theoretical base for the audiovisual i eld, Finn warned, Without a theory which produces hypotheses for research, there can be no expanding knowledge and technique.And without a constant attempt to assess practice so that the theoretical implications may b e teased out, there can be no assurance that we will ever have a theory or that our practice will make sense. (p. 14) Finn dedicated his career to rectifying this dei ciency in the i eld, and the resulting impact of his work on the 1963 dei nition is evident. Advancing an argument that audiovisual communications was a theory was an attempt to address the â€Å"lack of content† cited by Finn (1953). e Commission identii ed â€Å"the planning, production, selection, management, and utilization of both components and entire instructional systems† (Ely, ER5861X_C010. indd 263 ER5861X_C010. indd 263 8/16/07 6:24:24 PM 8/16/07 6:24:24 PM264 JANUSZEWSKI AND PERSICHITTE 1963, p. 19) as tasks performed by practitioners in the i eld directly related to Finn’s (1953) discussion of the â€Å"intellectual technique† of the audiovisual i eld—Finn’s i rst criterion for a profession. e i rst oi cial dei nition of educational technology can be viewed as an a ttempt to bring together remnants of theory, technique, other academic research bases, and history contained in the audiovisual literature, into a logical statement closing the gap on the â€Å"poverty of thought† (Finn, 1953, p. 13) that characterized the audiovisual education movement. h e evolution of audiovisual communications (and later, educational technology) as a theory began to add â€Å"intellectual meat† to audiovisual practice.By merging the audiovisual communications concept with the process orientation of the i eld into a new intellectual technique grounded in theory, the Commission strengthened the professional practice and of ered a direction for further growth as a profession. Emergence of a Process View Included among the many factors contributing to the development of the process view of educational technology were the two beliefs held by the most inl uential and prominent individuals involved with the audiovisual i eld: (1) that technology was prima rily a process (Finn, 1960b) and (2) that communication was a process (Berlo, 1960; Gerbner, 1956). e conceptual view of educational technology as a way of thinking and a process was established by the 1963 dei nition. h e intention of the Commission that produced the i rst oi cial dei nition of the i eld was â€Å"to dei ne the broader i eld of instructional technology which incorporates certain aspects of the established audiovisual i eld† (Ely, 1963, p. 3). Not unexpectedly, the 1963 dei nition drew some critique as it was applied to the emerging i eld of the 1960s and 1970s.Prominent individuals involved with audiovisual education, such as James Finn (1957; 1960a) and Charles Hoban (1962), had previously used the term technology when referring to the activities of the audiovisual i eld. Donald Ely (1973; 1982) observed that the use of the word control in the 1963 dei nition was problematic for many individuals involved with educational technology. Ely (1982) explained, â €Å"h e strong behavioral emphasis at the time seemed to call for the word ‘control’† (p. 3).He noted that the word facilitate was substituted by many professionals â€Å"to make the dei nition more palatable† (Ely, 1973, p. 52). Perhaps equally important was the desire by members of the i eld to move away from a behaviorally based psychology to a more humanistic psychology (Finn, 1967).

A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 265 Criticisms of the 1963 Dei nition As noted in the introduction, no one dei nition can be the dei nition, and there were criticisms of the 1963 dei nition.James Knowlton (1964), a faculty member at Indiana University, was a consultant for the 1963 Commission on Dei nition and Terminology. In an essay that reviewed the 1963 dei nition, Knowlton stated that the dei nition itself was â€Å"couched in semiotical termsâ €  (p. 4) but that the conceptual structure used in the rationale for the 1963 dei nition â€Å"was couched in learning theory terms [and] this disjunction produced some surprising anomalies† (p. 4). Knowlton’s argument was based on a need for conceptual and semantic consistency in the dei nition.Knowlton argued that failing to pair the language of the dei nition with the language of the conceptual structure in the rationale resulted in a general lack of clarity about this new concept. h is lack of clarity in turn caused confusion in the direction of research and practice in the i eld. Less than a decade later, Robert Heinich (1970) saw a need to redei ne the i eld of educational technology for two reasons. First, he was critical of the â€Å"communications† based language used in the 1963 dei nition. Heinich argued that this language was too complicated for school personnel to interpret and apply.Second, Heinich argued that the power to make many of the deci sions regarding the use of technology in schools should be transferred from the teacher to the curriculum planners. Heinich’s argument for changing the dei nition was based on both linguistic concerns and evolutionary changes in the functions of practitioners in the i eld. Heinich promoted an approach to schooling where specialists would decide when and where schools would use technology. h is position was dif erent from that which was discussed in the rationale for the 1963 dei – nition.In the rationale for the 1963 dei nition, teachers were viewed as partners of educational technologists rather than as their subordinates (Januszewski, 2001). Forces Impelling a New Dei nition Other contemporary issues emerged which began to inl uence the i eld. h e report of the Presidential Commission on Instructional Technology (1970) stated that instructional technology could be dei ned in two ways: In its more familiar sense it means the media born of the communications revolution which can be used for instructional purposes alongside the teacher, textbook and blackboard.In general, the Commission’s report follows this usage . . . the commission has had to look at the pieces that ER5861X_C010. indd 265 ER5861X_C010. indd 265 8/16/07 6:24:25 PM 8/16/07 6:24:25 PM266 JANUSZEWSKI AND PERSICHITTE make up instructional technology: television, i lms, overhead projectors, computers and the other items of â€Å"hardware and sot ware. † (p. 19) h e second and less familiar dei nition . . . (Instructional technology) . . . s a systematic way of designing, carrying out, and evaluating the total process of learning and teaching in terms of specii c objectives, based on research in human learning and communication and employing a combination of human and nonhuman resources to bring about more ef ective instruction. (Commission on Instructional Technology, 1970, p. 19) Educational technology professionals responded to this report in a special section of Audi ovisual Communications Review (1970). h e professional reviews of the government report were mixed at best. Ely (Ely et al. 1970) of Syracuse University thought that the Commission’s overall ef ort was commendable given its lot y charge. Earl Funderburk (Ely et al. , 1970) of the NEA called the recommendations a balanced program. But David Engler (Ely et al. , 1970) of the McGraw-Hill Book Company disapproved of the Commission’s ef ort to relegate the process-based dei nition of instructional technology to some â€Å"future† role. Leslie Briggs (Ely et al. , 1970) of Florida State University accused the Presidential Commission of providing a â€Å"two-headed image† of instructional technology by stressing both a hardware and a process orientation of the concept. e contributors to this special section of Audiovisual Communications Review (1970) were generally dissatisi ed with the â€Å"two-headed† orientation primarily because of the confusion it m ight cause among the potential client groups of educational technology. h ey viewed the hardware orientation favored by the Presidential Commission as a setback for the profession. It meant the unacceptable return to the â€Å"audiovisual aids† and â€Å"technology as machine† conceptions of educational technology. h is orientation also implied the de-emphasizing of research and theory.Given these professional discussions and developments, professionals in the i eld believed that a new dei nition of educational technology was necessary. The 1972 Definition By 1972, through evolution and mutual agreement, the DAVI had become the AECT. Along with the organizational change came a change to the dei nition. ER5861X_C010. indd 266 ER5861X_C010. indd 266 8/16/07 6:24:25 PM 8/16/07 6:24:25 PM10. A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 267 h e newly formed AECT dei ned the term educational technology rather than the term audiovisual communications a sEducational technology is a i eld involved in the facilitation of human learning through the systematic identii cation, development, organization and utilization of a full range of learning resources and through the management of these processes. (Ely, 1972, p. 36) As a member of the group that wrote several of the early drat s of the 1972 dei nition, Kenneth Silber (1972) was successful in including changes in many of the roles and functions of the practitioners of the i eld as part of that dei nition.Silber introduced the term learning system which combined ideas of the open classroom movement with some of the concepts of educational technology. Like Heinich’s (1970) perspective, Silber’s (1972) â€Å"learning system† (p. 19) suggested changes in the roles of the teacher and the educational technologist. Unlike Heinich, Silber supported the idea that learners should make many decisions regarding the use of educational technology themselves. Educational techno logists would produce a variety of programs and designs that learners would use or adapt to meet their own â€Å"long-range learning destination† (p. 1). Silber’s position was that the teacher should be more a â€Å"facilitator of learning† and less a â€Å"teller of information. † A Dei nition Based on h ree Concepts h ere are three concepts central to the 1972 dei nition characterizing educational technology as a i eld: a broad range of learning resources, individualized and personalized learning, and the use of the systems approach. â€Å"It is these three concepts, when synthesized into a total approach to facilitate learning, that create the uniqueness of, and thus the rationale for, the i eld† (Ely, 1972, p. 7). Examining these three concepts along with the idea of educational technology as a â€Å"i eld† is crucial to understanding the AECT’s (1972) dei nition of educational technology. It is particularly important to recognize that dif erent interpretations of these three concepts would result in dif ering conceptions of the i eld through the next three decades. h e dif erent interpretations and relative emphases of these concepts were due in large part to dif erences in educational philosophy and educational goals.Dif ering interpretations of these concepts would also have the more visible ef ect of substantially dif erent products and processes developed in the i eld. h e writers of the 1972 dei nition seemed to be aware that the major concepts could be interpreted dif erently, and they seemed to be interested ER5861X_C010. indd 267 ER5861X_C010. indd 267 8/16/07 6:24:26 PM 8/16/07 6:24:26 PM268 JANUSZEWSKI AND PERSICHITTE in including individuals with dif erent philosophical and academic backgrounds in the i eld. e writers of the 1963 dei nition and its supporting rationale seemed less concerned with accommodating divergent educational philosophies. Perhaps this was due to the fact that the 1963 dei n ition was the i rst formal attempt to dei ne educational technology. Such an under taking was formidable enough. Perhaps it was because the writers of the 1972 dei – nition paid more attention to the discussions of educational philosophy in the literature from the rest of the i eld of education.Perhaps it was because the 1963 dei nition viewed educational technology as an educational theory and, potentially, as an educational philosophy itself. Regardless, there is no doubt that by 1972, the authors of the dei nition of educational technology chose to consider educational technology a i eld of study and not as a specii c theory (Januszewski, 1995, 2001). Educational Technology as a Field h e decision to refer to educational technology as a i eld of study rather than a theory or a branch of theory had at least four results: (1) we acknowledged that there was more than one theory of educational technology, ore than one way to think about the role(s) of educational technology; ( 2) the dei nition prompted signii cant philosophical discussions by members of the profession; (3) the use of the word i eld encompassed both the â€Å"hardware† and â€Å"process† orientations of instructional technology described by the Presidential Commission (1970); and (4) this dei nition was based on the â€Å"tangible elements† (Ely, 1972) that people could observe. e 1972 dei nition essentially dei ned educational technology by role and function rather than as an abstract concept, as was the case for the 1963 dei nition, where educational technology was viewed as a theory. h e concept of â€Å"i eld† has been a thorny one for educational technologists. Like many areas of study within education, it is very dii cult to discuss educational technology without using the word i eld as a descriptor. Certainly audiovisual professionals used the term to describe the â€Å"audiovisual i eld† before the terms instructional technology or educational te chnology were ever used. e 1963 dei nition statement frequently used i eld (Ely, 1963) to move the discussion along, even though it was argued that educational technology was a theory or branch of theory. On the surface, the use of i eld seems a rather inescapable semantic problem when speaking of educational technology. But it is signii cant that the writers of the 1972 dei nition chose to use i eld rather than theory in the dei nition because the use of the word i eld established a territory. It also provided certain legitimacy to ef orts to advance ER5861X_C010. ndd 268 ER5861X_C010. indd 268 8/16/07 6:24:26 PM 8/16/07 6:24:26 PM10. A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 269 both products and processes. h e consequences of this decision were anticipated by Finn (1965), who proclaimed Properly constructed, the concept of instructional or educational technology is totally integrative. It provides a common ground for all professionals, no matter in what aspect of the i eld they are working: it permits the rational development and integration of new devices, materials, and methods as they come along. e concept is so completely viable that it will not only provide new status for our group, but will, for the i rst time, threaten the status of others [italics added]. (p. 193) Criticism of the 1972 Dei nition h e 1972 dei nition was not the object of numerous criticisms as was the 1963 dei nition, probably because it was considered only an interim dei nition (Ely, 1994). Only one such article appeared in the literature of the i eld of educational technology—a critique was written by Dennis Myers, then a graduate student at Syracuse University, and Lida Cochran, a faculty member at the University of Iowa (Myers & Cochran, 1973). e brief analysis by Myers and Cochran (1973) articulated at least i ve dif erent criticisms. First, they proposed including a statement in the rationale for the dei nition stating that students have a rig ht of access to technological delivery systems as part of their regular instruction. Including such a statement follows from Hoban’s (1968) discussion on the appropriateness of technology for instruction in a technological society. Second, Myers and Cochran argued that the 1972 dei nition statement was weakened by neglecting to include a theoretical rationale for the dei nition. is criticism, which correctly pointed out that the dei nition is lacking a unii ed theoretical direction, supported Heinich’s (1970) assertions in his philosophical view of the i eld. In a third point, Myers and Cochran (1973) criticized the limited role that the educational technologist was provided in the description of the systems approach provided in the dei nition. In a fourth point, they discussed the shortcomings of the terminology used to discuss the domains and roles in educational technology.Perhaps the most interesting point made in this analysis concerned the relationship of educati onal technology to the rest of the i eld of education. In noting the problem of dei ning the i eld by the functions performed, Myers and Cochran (1973) pointed to the importance of considering the purpose of education. ER5861X_C010. indd 269 ER5861X_C010. indd 269 8/16/07 6:24:26 PM 8/16/07 6:24:26 PM270 JANUSZEWSKI AND PERSICHITTE What is important is that certain functions get done in education. h at generalization is important because it conveys an attitude that transcends narrow professional nterests and strikes a note of community and cooperativeness, qualities which are essential to the solution of problems facing education and society. (p. 13) Here, Myers and Cochran (1973) seemed to be chastising the writers of the 1972 dei nition for being overly concerned with intellectual territory and the roles performed in the i eld of educational technology. h is particular criticism lost only a little of its sharpness when it was viewed in light of earlier comments made about the inap propriateness of the limited role assigned to educational technologists in the dei nition (Januszewski, 2001).In summary, by 1972, the name of the concept had changed from audiovisual communications to educational technology. h e organizational home for professionals in the i eld had changed name: from DAVI to AECT. h ere had been substantial changes in our schools, hardware, and other technological innovations during the nine years since the writing of the i rst dei nition. Educational technology was now identii ed as a i eld of study, open to interpretation by those who practiced within it. e 1972 dei nition rel ected these interpretations but was intended to be only a temporary measure. Almost as soon as it was published, work began on the next dei nition. The 1977 Definition In 1977, the AECT revised its dei nition of educational technology with its third version: Educational technology is a complex, integrated process, involving people, procedures, ideas, devices and organizati on, for analyzing problems and devising, implementing, evaluating and managing solutions to those problems, involved in all aspects of human learning.In educational technology, the solution to problems takes the form of all the Learning Resources that are designed and/or selected and/or utilized to bring about learning; these resources are identii ed as Messages, People, Materials, Devices, Techniques, and Settings. h e processes for analyzing problems, and devising, implementing and evaluating solutions are identii ed by the Educational Development Functions of Research h eory, Design, Production, Evaluation Selection, Logistics, Utilization, and Utilization Dissemination. h e processes of directing or coordinating one or more of hese functions are identii ed by the Educational Management Functions of Organizational Management and Personnel Management.

A HISTORY OF THE AECTâ₠¬â„¢S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 271 h e Dei nition of Educational Technology (AECT, 1977) was a 169-page book intended to accomplish two things: (a) systematically analyze the complex ideas and concepts that were used in the i eld of educational technology, and (b) show how these concepts and ideas related to one another (Wallington, 1977). is publication included the dei nition of educational technology (which comprises 16 pages of the text), a history of the i eld, a rationale for the dei nition, a theoretical framework for the dei nition, a discussion of the practical application of the intellectual technique of the i eld, the code of ethics of the professional organization, and a glossary of terms related to the dei nition. Educational Versus Instructional Technology h e conceptual dif erence between the terms educational technology and instructional technology constituted a large portion of the analysis of this book.Understanding how the authors of the 1977 dei niti on viewed the relationship of instructional technology to educational technology is essential to understanding the 1977 dei nition and its theoretical framework. h e basic premise of this distinction was that instructional technology was to educational technology as instruction was to education. h e reasoning was that since instruction was considered a subset of education then instructional technology was a subset of educational technology (AECT, 1977). For example, the concept of educational technology was involved in the solution of problems in â€Å"all aspects of human learning† (p. ). h e concept of instructional technology was involved in the solution of problems where â€Å"learning is purposive and controlled† (p. 3). Educational Technology as a Process Two other complex conceptual developments were also undertaken by the authors of the 1977 dei nition, which were interrelated. First, the 1977 dei – nition of educational technology was called a â€Å"pr ocess† (AECT, 1977, p. 1). h e authors intended the term process to connote the idea that educational technology could be viewed as a theory, a i eld, or a profession.Second, the systems concept was infused throughout the entire dei nition statement and in all the major supporting concepts for the dei nition in both its descriptive and prescriptive senses. h e authors of the 1977 dei nition connected these two conceptual developments by saying that the use of the systems concept was a process (AECT, 1977). As one of the three major supporting concepts for the 1972 dei nition of educational technology, the systems approach had become the basis for the ER5861X_C010. ndd 271 ER5861X_C010. indd 271 8/16/07 6:24:27 PM 8/16/07 6:24:27 PM272 JANUSZEWSKI AND PERSICHITTE dei nition itself by 1977. h rough their ef orts to reinforce the process conception of educational technology, the leadership of the i eld now assumed that all of the major supporting concepts of the dei nition were t ied to, or should be viewed in light of, the systems approach. h e three major supporting concepts of the 1977 dei nition were learning resources, management, and development.Learning resources were any resources utilized in educational systems; a descriptive use of the systems concept the writers of the 1977 dei nition called â€Å"resources by utilization. † Authors called the resources specii cally designed for instructional purposes, a prescriptive use of the systems approach, â€Å"resources by design† or â€Å"instructional system components† (AECT, 1977). Like the concept of learning resources, management could be used in a descriptive fashion to describe administrative systems or in a prescriptive way to prescribe action. e concept of management was ot en used as a metaphor for the systems approach in education (Heinich, 1970). h e term instructional development was frequently used to mean the â€Å"systems approach to instructional development† o r â€Å"instructional systems development† (Twelker et al. , 1972). h e fact that the management view of the systems approach to instruction ot en included an instructional development process and the fact that instructional development models frequently included management as a task to be completed in the systems pproach to instructional development further intertwined the systems concept with the process view of educational technology. h ese descriptive and prescriptive interpretations of the 1977 dei nition would inl uence future dei nitions. As previously noted, the predilection that educational technology was a process was not new when the 1977 dei nition was written. Process was one of the three major supporting concepts incorporated into the rationale of the 1963 dei nition (Ely, 1963).Believing that educational technology was a process provided one of the major reasons that the leadership of the profession tended to reject the report of the Presidential Commission on Instructional Technology (1970), which focused heavily on the hardware of the i eld in its i rst dei nition of instructional technology. h e authors of the 1977 dei nition, who purposefully used the term process to develop a systematic and congruent scheme for the concept of educational technology, said, h e dei nition presented here dei nes the theory, the i eld, and profession as congruent. is occurs because the dei nition of the i eld of educational technology is directly derived from, and includes, the theory of educational technology, and the profession of educational technology is directly ER5861X_C010. indd 272 ER5861X_C010. indd 272 8/16/07 6:24:28 PM 8/16/07 6:24:28 PM10. A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 273 derived from, and includes, the i eld of educational technology. (AECT, 1977, p. 135) In the end, the ef ort to demonstrate the congruence of the major concepts involved with educational technology created as many issues for the i eld as it resolved.Five immediate advantages for describing educational technology as a process were (1) the use of the term process reinforced the primacy of the process view of educational technology over the product view of educational technology. h e process view had been outlined in the 1963 dei nition statement, but the report of the Presidential Commission on Instructional Technology (1970) appeared to reverse this emphasis. (2) h e term process would ground the dei nition of educational technology in the activities of its practitioners, activities that could be directly observed and verii ed. 3) h e term process could be used to describe educational technology as a theory, a i eld, or a profession. (4) h e term process allowed the further evolution of thought and research around the concept of systems. Finally, (5) an organized process implies the use of research and theory, which would reinforce the idea that educational technology was a profession. Educational Technology as F ield, h eory, or Profession h e authors of the 1977 dei nition argued that educational technology could be thought of â€Å"in three dif erent ways—as a theoretical construct, as a i eld, and as a profession† (AECT, 1977, p. 7). h ey continued, â€Å"None of the foregoing perspectives is more correct or better than the others. Each is a different way of thinking about the same thing† (p. 18). h e writers of the 1977 dei nition argued that the theoretical construct, the i eld, and the profession were all process based. h e term process described and connected all three of these perspectives of educational technology with a single word. Educational technology had been called a theory in the 1963 dei nition (Ely, 1963), and it had been called a i eld in the 1972 dei nition (Ely, 1972).New to the 1977 dei nition was the argument that educational technology was also a profession. Prior to the publication of the 1977 dei nition, the term profession was used in passing as it related to educational technology. Since Finn (1953) had argued that the i eld had not yet reached professional status, members of the i eld (e. g. , Silber, 1970) had made few attempts to analyze educational technology systematically as a profession. Using Finn’s criteria, the writers of the 1977 dei nition argued that educational technology was now a profession.Depending upon the interpretation and application of the systems concept, educational technology could be explained as a theory, a i eld, or a profession ER5861X_C010. indd 273 ER5861X_C010. indd 273 8/16/07 6:24:28 PM 8/16/07 6:24:28 PM274 JANUSZEWSKI AND PERSICHITTE in the 1977 dei nition. h e impact of using the term process to describe educational technology as a theory, a i eld, or a profession hinged on these dif ering interpretations of the systems approach, once again prompting discussions and philosophical debates among prominent educational technologists. e period of the 1980s was not so focused on c riticism of the 1977 dei nition as much as characterized by broad academic wrangling over the interpretation and application of the dei nition (Januszewski, 1995, 2001). h e three major supporting concepts of the 1977 dei nition—learning resources, management, and development—could also be interpreted dif erently based on divergent conceptions of the systems approach. h e dif erent interpretations of learning resources, management, and development also provided the writers of the 1977 dei nition with a rationale to distinguish between educational technology and instructional technology.The 1994 Definition By 1994, the dei nition of educational technology had nearly come full circle. h e dei nition that was produced in 1994 read, â€Å"Instructional technology is the theory and practice of design, development, utilization, management, and evaluation of processes and resources for learning† (Seels & Richey, 1994, p. 1). h ere are no new concepts included in the 19 94 dei nition. What was new was the identii cation of multiple theoretical and conceptual issues in the explanation of the dei nition. e 1994 dei nition was intended to be much less complex than the 1977 dei nition. h e extent to which the writers were successful can be judged in part by reviewing the criticisms of the 1977 dei nition. h e attempt by the writers of the 1977 dei nition to show the congruence of educational technology and instructional technology revealed a conceptual problem for the i eld. h e dei nition of educational technology, which was concerned with â€Å"all aspects of human learning† (AECT, 1977, p. ), had become so broad that some individuals in the i eld of education pointed out that there was no dif erence between educational technology and curriculum, school administration, or teaching methods (Ely, 1982). Saettler (1990) wryly pointed out that the dei nition had become everything to everybody, and he dubbed the 1977 dei nition the â€Å"omnibus d ei nition. † Logical Problems h ere were also serious l aws in the reasoning and the conceptual interpretations used in the theoretical framework and rationale for the 1977 dei nition of educational technology.Establishing the dif erence between ER5861X_C010. indd 274 ER5861X_C010. indd 274 8/16/07 6:24:28 PM 8/16/07 6:24:28 PM10. A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 275 education and instruction, the authors argued, â€Å"Education, then, includes two classes of processes not included in instruction: those processes related to the administration of instruction . . . and those processes related to situations in which learning occurs when it is not deliberately managed† (AECT, 1977, p. 56).An example of learning not deliberately managed given in the discussion was â€Å"incidental learning† (p. 56). It was reasonable for the authors to argue that nondeliberately managed learning and/or incidental learning was part of the concept of education (Januszewski, 1997). However, the dei nitions of â€Å"technology† by Galbraith (1967), Hoban (1962), and Finn (1960a, 1965), which were used by the authors of the 1977 dei nition to discuss the term technology as it related to the concept of educational technology, all included the ideas of organization, management, and control (AECT, 1977). e writers of the 1977 dei nition considered organization, management, and control critical characteristics of technology; but these ideas were contrary to the idea of â€Å"incidental learning† and â€Å"learning that was not deliberately managed. † Education, at least as it was distinguished from instruction included in the rationale of the 1977 dei nition, did not seem compatible with technology. It is dii cult to conceive of a technology of the incidental, unmanaged, and unintended. e gains made in the organization of the framework of the concept of educational technology by distinguishing between education and instruction were lost when education was paired with technology (Januszewski, Butler, & Yeaman, 1996). h eory or theoretical construct. h e relationship of educational technology to â€Å"theory† presented another problem in the discussion of educational technology presented in the 1977 dei nition and rationale. ere are three ways in which the concept of theory is related to educational technology in the 1977 dei nition statement: (1) the thought that educational technology was a â€Å"theoretical construct† (AECT, 1977, pp. 18, 20, 24); (2) the notion that educational technology itself was â€Å"a theory† (AECT, 1977, pp. 2, 135, 138); and (3) that the â€Å"dei nition of educational technology was a theory† (AECT, 1977, pp. 4, 20, 134). To some degree, all three of these discussions of theory and educational technology are accurate, but they cannot be used interchangeably as they are in the 1977 dei nition.A theoretical construct is not the same as a t heory; nor is it the case, that because a dei nition of a concept is a theory, the concept itself a theory. h e word theory has been used in at least four ways in the literature of the i eld of education: (1) the â€Å"law like† theory of the hard sciences; (2) theories that are supported by statistical evidence; (3) theories that identify variables that inl uence the i eld of study; and (4) theory as a systematic analysis of a set of related concepts (Kliebard, 1977). ER5861X_C010. indd 275 ER5861X_C010. ndd 275 8/16/07 6:24:29 PM 8/16/07 6:24:29 PM276 JANUSZEWSKI AND PERSICHITTE h e fourth sense of theory is of interest to this analysis of the 1977 dei nition of educational technology. Systematic analyses of any abstract concept can be said to be theories of that concept. Referring to educational technology as a theoretical construct, or a theory, or calling the dei nition of educational technology a theory may be accurate if the construct or theory includes a systematic an alysis of the concept of educational technology. e writers of the 1977 dei nition provided criteria for â€Å"theory† that was not theory as a systematic analysis of related concepts. h e 1977 view of theory was an attempt to establish general principles and predict outcomes (AECT, 1977). h is approach was substantially dif erent from the usage of the word theory in the 1963 dei nition statement. Further confusion arises because of the writers’ claim that educational technology did indeed meet the criteria for being a predictive theory (Januszewski, 1995, 2001).Certainly â€Å"educational technology† is a theoretical construct. â€Å"Educational technology† may also be considered a theory depending on what exactly is intended by the word theory. The 1977 definition of educational technology is a theory about the abstract concept of â€Å"educational technology. † But because the definition of the concept of educational technology may be a theory of educational technology, it does not necessarily follow that the concept of educational technology is itself a theory.This is similar to saying that a definition of the concept of democracy may be a theory of democracy but that the concept of democracy itself is not a theory. Few involved in the field of educational technology adopted this systematic treatment of the concepts provided in the 1977 definition. Many in the field adopted only portions of the definition (e. g. , Gustafson, 1981). Certain parts of the definition and the supporting statements were cited by scholars in order to make erudite points about the field of educational technology (e. . , Romiszowski, 1981), but a reading of the literature of the field during this era reveals that the whole of the conceptual framework provided in the 1977 definition, specifically the part intended to distinguish educational technology from instructional technology, was not widely accepted by the professionals in the field of educati onal technology (Seels & Richey, 1994). This lack of acceptance led to the label changes in the 1994 definition. Distinguishing between educational and instructional. e ef ort to revise the 1977 dei nition addressed some of the conceptual incongruencies of previous dei nitions. h e i rst of these was the dif erence between educational and instructional technology. Unlike the writers of the 1977 dei nition, who sought to distinguish between educational technology and instructional technology, ER5861X_C010. indd 276 ER5861X_C010. indd 276 8/16/07 6:24:29 PM 8/16/07 6:24:29 PM10. A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 277 the authors of the 1994 dei nition acknowledged that this problem had no easy answer. ey admitted, â€Å"At present the terms ‘Educational Technology’ and ‘Instructional Technology’ are used interchangeably by most professionals in the i eld† (p. 5). But they argued, Because the term ‘Instructional T echnology’ (a) is more commonly used today in the United States, (b) encompasses many practice settings, (c) describes more precisely the function of technology in education, and (d) allows for an emphasis on both instruction and learning in the same dei nitional sentence, the term ‘Instructional Technology’ is used in the 1994 dei nition, but the two terms are considered synonymous. Seels & Richey, 1994, p. 5) With that, the oi cial label of the i eld was changed from â€Å"educational technology† to â€Å"instructional technology,† although it was quite acceptable to continue to use the term educational technology. Underlying Assumptions Seels and Richey (1994) did dif erentiate the 1994 dei nition from previous dei nitions by identifying and analyzing some of the assumptions that underlie this dei nition. Identii ed assumptions included Instructional technology has evolved from a movement to a i eld and profession.Since a profession is concerned with a knowledge base, the 1994 dei nition must identify and emphasize instructional technology as a i eld of study as well as practice (p. 2). A revised dei nition of the i eld should encompass those areas of concern to practitioners and scholars. h ese areas are the domains of the i eld (p. 2). Both process and product are of vital importance to the i eld and need to be rel ected in the dei nition (p. 2). Subtleties not clearly understood or recognized by the typical Instructional Technology professional should be removed from the dei nition and its more extended explanation (p. ). It is assumed that both research and practice in the i eld are carried out in conformity with ethical norms of the profession (p. 3). Instructional technology is characterized by ef ectiveness and ei – ciency (p. 3). h e concept of systematic is implicit in the 1994 dei nition because the domains are equivalent to the systematic process for developing instruction (p. 8). †¢ †¢ †¢ à ¢â‚¬ ¢ †¢ †¢ †¢ ER5861X_C010. indd 277 ER5861X_C010. indd 277 8/16/07 6:24:29 PM 8/16/07 6:24:29 PM278 JANUSZEWSKI AND PERSICHITTE h e inclusion of these ssumptions in the analysis and explanation accompanying the 1994 dei nition allowed for the publication of a dei nition that was much more â€Å"economical† than were previous dei nition ef orts. h eory and Practice h e authors of the 1994 dei nition stated that the dei nition was composed of four components: (a) theory and practice; (b) design, development, utilization, management and evaluation; (c) processes and resources; and (d) learning. h ese components were not necessarily new; but in this dei nition, they were reorganized, simplii ed, and connected, in a way making the 1994 dei nition unique. e 1994 dei nition used the phrasing included in the 1963 dei nition when it called instructional technology â€Å"the theory and practice of. † And the authors argued, â€Å"A profession must have a knowl edge base that supports practice† (Seels & Richey, 1994, p. 9). h e authors used a simple but rather clear notion that â€Å"theory consists of the concepts, constructs, principles, and propositions that contribute to the body of knowledge† and that â€Å"practice is the application of the knowledge† (p. 11).In so doing, the authors cleared up the problem of the meaning of theory that they had inherited from the writers of the 1977 dei nition, a dei nition of theory that had been too precise. Domains h e concepts (or â€Å"domains† of the 1994 dei nition) of design, development, utilization, management, and evaluation comprise the accepted knowledge base of the i eld today as evidenced by the Standards for the Accreditation of School Media Specialist and Educational Technology Specialist Programs (AECT, 2000).When these concepts are taken together and conducted in sequential order, they are the same as the stages of â€Å"development† described in t he 1977 dei nition. h ese concepts are directly traceable to the idea of educational engineering developed by W. W. Charters (1945). It is important to realize that the authors of the 1994 dei nition did not intend that practitioners of educational technology perform all of these tasks in the sequential order. Specializing in or focusing on one of these tasks would include broad practitioners in the i eld (Seels & Richey, 1994).Seels and Richey (1994) provided dei nitions of processes and resources: â€Å"A process is a series of operations or activities directed towards a particular end† (p. 12). â€Å"Resources are sources of support for learning, including support systems and instructional materials and environments† (p. 12). h ese descriptions allowed the authors to (a) use process to reinforce notions of ER5861X_C010. indd 278 ER5861X_C010. indd 278 8/16/07 6:24:30 PM 8/16/07 6:24:30 PM10.A HISTORY OF THE AECT’S DEFINITIONS OF EDUCATIONAL TECHNOLOGY 279 eng ineering and science in instruction; (b) maintain the distinction between resources as things and processes; and (c) be consistent with terminology used in all three previous dei nitions. h e concept of learning was not new to the 1994 dei nition; however, the dei nition of learning intended by the authors was new. In previous dei nitions, the term learning was intended to connote a change in behavior such as advocated by Tyler (1950). But the authors of the 1994 dei nition wanted to move away from a strong behaviorist orientation. ey argued, â€Å"In this dei nition learning refers to the ‘relatively permanent change in a person’s knowledge or behavior due to experience’† (Mayer, 1982, as cited in Seels & Richey, 1994, p. 12). Including the phrase â€Å"due to experience† also aided in moving away from causal connections and allowed for incidental learning. h is interpretation signaled the acceptance of a dif erent kind of science in education: one less grounded on prediction and control and more interested in applying other theoretical and research principles to the instructional process.Criticism of the 1994 Dei nition h e primary criticism of the 1994 dei nition is that instructional technology appeared to look too much like the systems approach to instructional development while changes in the practice of the i eld (e. g. , constructivistbased initiatives and the general acceptance of computer innovations in classroom methodologies) made the 1994 dei nition too restrictive for mainstream teachers and school administrators as well as researchers and scholars. h ese criticisms and further evolution of the research and practice in the i eld led to a need for reconsideration and evision of this dei nition at er more than a decade of use. The Current Definition h e task force empanelled by AECT to review the 1994 dei nition wrestled with the historical issues presented here and with other issues of perception, changing employm ent and training expectations, semantics, and a strong desire to develop a dei nition that both served to include the broad variety of practitioners in this i eld and one which would prompt renewed attention to the theory and research so critical to our continued contributions to learning.In a sense, we are not so far removed in this century from the professional goal stated in the 1963 dei nition: ER5861X_C010. indd 279 ER5861X_C010. indd 279 8/16/07 6:24:30 PM 8/16/07 6:24:30 PM280 JANUSZEWSKI AND PERSICHITTE It is the responsibility of educational leaders to respond intelligently to technological change . . . If the DAVI membership is to support the leadership in such bold steps, dei nition and terminology as a basis for direction of professional growth is a prime prerequisite . . Now that the i eld of audiovisual communications, the largest single segment of the growing technology of instruction, has reached the point of decision making, we i nd ourselves in the same quandary ot her i elds have discovered when they have attempted to dei ne their i elds: i. e. , dei nition exists at various levels of understanding but no one dei nition can be the dei nition.
