Advances in computing and information technology change the way people meet and communicate with them. People can meet, talk and work together outside of the traditional meeting and office space. For example, with the introduction of a program designed to help people schedule meetings and facilitate decision-making or learning, this weakens geographical constraints and changes the dynamics of interpersonal communication. Information technology also greatly affects the way people teach and learn.
As new information technologies penetrate the workplace, home and classrooms, research into user acceptance of new technologies has begun to receive great attention from professionals as well as academic researchers. Software and software industries developers are beginning to realize that a user's lack of acceptance of technology can lead to a loss of money and resources.
In examining user acceptance and use of technology, TAM is one of the most cited models. The Technology Acceptance Model (TAM) was developed by Davis to explain computer use behavior. The theoretical basis for the model is Fishbein and Ajzen's theory of rational action (TRA).
The Technology Acceptance Model (TAM) is an information system (a system consisting of a network of all communication channels used within an organization) that designs how users can accept and use technology, the model indicates that when users are introduced to a new software package, there are a number of factors That affect their decision on how and when to use it, in particular:
Perceived Benefit (PU) – This has been defined by Fred Davis as "the degree to which a person believes that the use of a particular system would enhance his or her job performance".
Perceived Ease of Use (PEOU) defined Davis as "the degree to which a person believes that using a particular system will be effortless" (Davis, 1989).
The goal of TAM is "to provide an illustration of factors that determine computer acceptance in general, and that is able to explain user behavior across a wide range of computing technologies to the end user and user groups, while being volatile and theoretically justified."
According to TAM, if the user thinks that a certain technology is beneficial, you will believe in a positive use relationship. Since voltage is a limited resource, the user is likely to accept an application when he / she feels easier to use than another application. As a result, high-level educational technology of PU and PEOU is likely to stimulate positive perceptions. The relationship between PU and PEOU is that PU mediates the effect of PEOU on intended position and use. In other words, while the PU has direct effects on the situation and use, PEOU influences the situation and is used indirectly through the PU.
User acceptance is defined as "a clear desire within a user group to employ information technology for the tasks that are designed to support it" (Dillon & Morris). Although this definition focuses on the intended and intended uses of technology, studies indicate that individual perceptions of information technology are likely to be affected by the objective characteristics of technology, as well as interactions with other users. For example, to what extent one evaluates new technology as useful, it is likely that he / she will use it. At the same time, his perception of the system is affected by the way the people around him evaluate and use the system.
Information technology studies consistently indicate that user attitudes are an important factor affecting the success of the system. Over the past few decades, many definitions of the position have been proposed. However, all theories consider the relationship to be the relationship between a person and the object (Woelfel, 1995).
In the context of information technology, it is an approach to the study of the situation – the technology acceptance model (TAM). TAM suggests that users formulate a positive attitude toward technology when they see technology as useful and easy to use (Davis, 1989).
A review of scientific research on acceptance and use of IS indicates that TAM has emerged as one of the most influential models in this research, and TAM represents an important theoretical contribution to understanding the behaviors of using IS and IS. However, this model – with its original emphasis on designing system properties – does not explain the social impact of the adoption and use of new information systems.
