Technology Acceptance Model Davis 1986 – The technology acceptance model (TAM) is an information system theory that models how users accept and use technology.
The actual use of the system is the point D where people use technology. Behavior is a factor that forces people to use technology. Consumption of behavior (BI) is affected by the attitude (a) which is the geral impression of technology.
Technology Acceptance Model Davis 1986
The model suggests that users be tested with new technology, a number of factors implement their decision on how and WH will use it, especially:

External variables such as social influence are an important factor in determining attitude. While these things (TAM) are in place, people will have an attitude and integer to use technology. But perception can change age and gder because everyone is different.
Tam 3 was also proposed in connection with e-commerce by including the effects of trust and perceived risk on the use of the system.
TAM is one of Ajz’s most inflational exceptions and Fishbein’s theory on motivated action (TRA) in literature. Davis’s technology acceptance model (Davis, 1989; Davis, Bagozzi, & Warshaw, 1989) is the most applied model for user acceptance and technology use (VKatesh, 2000) . It was developed by Fred Davis and Richard Bagozzi.
TAM replaces many of the TRA attitude measures with the two technical acceptance measures-for use and usability. Tra and tame, both of which have strong elements of behavior, assume that as someone forms a tune to act, that they will be free to act without restriction. In the real world, there will be many restrictions, such as limited freedom to act.
Technology Acceptance Model
Since new technology such as personal computers is complex and an element of uncertainty found in the minds of decision makers regarding their successful assumption, people make up attitudes and impressions to try to learn how to use it -New technology before starting targeted efforts. Attitudes for use and impressions for use can be misrepresented or have no conviction or may occur only after preliminary efforts to learn how to use technology. Therefore, the actual use cannot be a direct or immediate consequence of such attitudes and intations. [6]
Previous research on disseminating innovations also suggested a promint role in the friendship of the perceived user. Tornnatzky and Klein
Analyzed the assumption and found that compatibility, relative advantage and complexity had the most significant conditions with the assumption of a wide range of types of innovation. Eason studied usability perceived in terms of a suitable betwe system, tasks and job profiles, using the terms “good” to describe the metric.
Legris, Ingham and Collerette suggest that the TAM should be extended to include variables that are responsible for change processes and that this can be achieved by adopting the innovation model for TAM.
Testing A Novel Extended Educational Technology Acceptance Model Using Student Attitudes Towards Virtual Classrooms
Much to achieve focus on testing the robustness and validity of the questionnaire used by Davis. Adams et al.
To show the validity and reliability of his instrument and its measurement scales. They also expanded it to different settings and with two different samples showed the internal texture and reliability replication for both scales. Hdrickson et al. High reliability and good reliability of the test review have been found.
We found that the instrument had a predictable validity for an intture, use and self-reported attitude.
The sum of this research has confirmed the validity of Davis closed and supports its use with different users’ populations and various software elections.

) Davis’s job replication. They were critical to the measurement model used and postulated a different model based on three constructions: usability, efficiency and user friendship. These results do not appear to have been replicated yet. However, some aspects of these results have been tested and supported by a worker
Mark Keil and his colleagues developed (or perhaps more popular) Davis model for what they call the usability route / EOU, which is a 2 × 2 grid where each quadrant represents a different combination of the two attributes. In relation to software use, this provides a mechanism for discussing the usability cut mix and EOU for special software packages, and to draw a different course if a different mix is desired, such as introducing Any more powerful software.
The TAM model has been used in most technical and geographical contexts. One of these contexts is healthcare, growing rapidly
Expash the TAM model to integrate the emotions and effect it can have on the behavioral behavior to accept technology. Specifically, they looked hot.

VKatesh and Davis expanded the original TAM model to explain the use of perceived use and use regarding social influence (subjective norms, voluntary, image) and cognitive instrument processes (employment student, quality of Production, show results, perceived the user friend). The extracted model, called TAM2, has been tested in both volunteers and mandatory environments. The results strongly supported TAM2.
In an attempt to integrate key competing user models, VKatesh et al. Formulated the uniform theory of acceptance and use of technology (UTAUT). This model has proven to exceed each of the individual models (69 PERCT adjusted R-Square).
In addition, writers Jun et al. They also believe that the model of technology acceptance is essential to analyze the factors that affect customers’ behavior towards online food delivery services. It is also a theoretical model generally adopted to demonstrate the acceptance of new fields of technology. The basis for TAM is a series of concepts that clarify and predict the behavior of people by their faith, attitudes and the intion of their behavior. In the TAM play the perceived user’s friendship and perceived usability, considered a geral conviction, a more important role than what saves beliefs in attitudes for the use of a certain technology.
Tam has been largely criticized, despite its free use, leading to original lawyers trying to define it several times. Tam criticism as a “theory” includes its dubious heuristic value, explanatory and predictable power, triviality and practical value.
Technology Acceptance Model A Literature Review From 1986 To 2013
Basat and Barks suggest that tam “Switches the occurrence of researchers away from other important research issues and created an illusion of progress in knowledge housing. Outside [sic] for a state of chaos and theoretical confusion” .
In Geral, Tam focuses on the individual “user” of a computer, with the concept of “perceived use”, with Estsion to achieve more and more factors to explain how a user “perceives” usability “, and ignores the Essential social processes are developing and implementing, without a doubt, more technology is actually better, and the social consequences of use are.
Experienced user friendship is less likely to be crucial to attitude and use according to telemedicine studies, the model of technology acceptance (TAM) is a theoretical framework developed to explain how l Users use and use technology. It is a generally used model that has been applied in several areas, including information, marketing and social sciences. Tam was first proposed by Fred Davis in 1986 and has since changed and has been extended by several researchers.
Tam consists of two basic components: perceived usability (PU) and perceived user friends (PEOU). PU refers to the point that a user believes that technology improves its performance or productivity. Peou refers to the point that the user considers that technology is easy to use. According to TAM, these two factors are the primary determinants for the acceptance and user use behavior.

While PU and PEOU are the primary factors in TAM, external factors can also affect the acceptance and behavior of the user’s use. These factors include social norms, organizational factors and individual differences. Social norms refer to the expectations and beliefs of others in the user’s social network. Organizational factors refer to user policies, procedures and culture. Individual differences refer to factors such as age, gender and experience.
The TAM has been widely used in various areas to study the adoption and behavior of user usage. Has been applied in relation to e-commerce, mobile technology, social media
And healthcare technology, among others. The TAM was also used to develop and evaluate interventions aimed at increasing the adoption and behavior of user usage.
Despite its widespread use, TAM has been criticized for its limited scope and foreseeable power. Some researchers have argued that the TAM fails to consider factors such as social influence, trust and perceived risk. Others have claimed that Tam does not sufficiently capture the complex nature of the user’s behavior.

In order to deal with part of TAM criticism, many researchers have proposed additions and model changes. For example, the uniform theory of acceptance and use of technology (UTAUT) contains additional factors such as performance expectation, expected effort, social influence and facilitation conditions. Other researchers have proposed amendments to TAM to add up to specific contexts or user groups.
