  Technology Acceptance Model
TAM is an adaptation of the Theory of Reasoned Action (TRA) to the field of IS. TAM posits that perceived usefulness and perceived ease of use determine an individual's intention to use a system with intention to use serving as a mediator of actual system use.
Attempts to extend TAM have generally taken one of three approaches: by introducing factors from related models, by introducing additional or alternative belief factors, and by examining antecedents and moderators of perceived usefulness and perceived ease of use (Wixom and Todd, 2005).

Following the theory of reasoned action (TRA) as applied to a technology-driven environment, technology acceptance model (TAM) variables (perceived usefulness and ease of use) are posited as key drivers of e-commerce acceptance.
The practical utility of TAM stems from the fact that e-commerce is technology-driven.
The proposed model integrates trust and perceived risk, which are incorporated given the implicit uncertainty of the e-commerce environment.

 Technology acceptance model - EduTech Wiki
The purpose of this model is to predict the acceptability of a tool and to identify the modifications which must be brought to the system in order to make it acceptable to users.
This model suggests that the acceptability of an information system is determined by two main factors: perceived usefulness and perceived ease of use.
As demonstrated in the theory of reasoned Action, the Technology Acceptance Model postulates that the use of an information system is determined by the behavioral intention, but on the other hand, that the behavioral intention is determined by the person’s attitude towards the use of the system and also by his perception of its utility.

TAM does not use Rogers’ constructs, but PEU and PU are meaningfully related to Rogers’ constructs Relative Advantage and Complexity and lead to similar results regarding diffusion outcomes (Moore and Benbasat, 1991; Karahanna, 1993).
TAM can be viewed as a parsimonious form of the Rogers model, with adaptations of constructs specific to IT.
The applicability of the TAM model suggests that Arab culture does not strongly mitigate against the cultural beliefs of perceived usefulness and perceived ease of use.

In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formulate a unified theory that integrates elements across the eight models, and (4) empirically validate the unified model.
The eight models reviewed are the theory of reasoned action, the technology acceptance model, a motivational model, the theory of planned behavior, a model combining the technology acceptance model and the theory of planned behavior, a model of PC utilization, innovation diffusion theory, and social cognitive theory.
UTAUT thus provides a useful tool for managers needing to assess the likelihood of success for new technology introductions and helps them understand the drivers of acceptance in order to proactively design interventions (including training, marketing, etc.) targeted at populations of users that may be less inclined to adopt and use new systems.

 Using perceived ease of use and perceived usefulness to predict acceptance of the World Wide Web
The Technology Acceptance Model (TAM) behavioural constructs of perceived usefulness and perceived ease of use were tested for predicting user acceptance of the World Wide Web (Web).
In an attempt to model this user adoption, this study began with a test of the principal behavioural constructs of Davis' [3] Technology Acceptance Model (TAM).
This later test was successful with the TAM adjusted goodness of fit of 0.890 once the additional construct, computer self-efficacy, was included in the Technology Acceptance Model.

 Empirical evaluation of the revised technology acceptance model
The research reported here (1) provides a confirmatory, empirical test of the revised TAM and (2) introduces an objective measure of technology acceptance, actual usage rather than self-report usage.
Subjects' beliefs about the usefulness and ease of use of an electronic mail system, their intentions to use the system, and their usage of it 15 weeks later were measured in a logitudinal study.
The results confirmed that the TAM is a valuable tool for predicting intentions to use an IS. The findings here combined with results from other studies in this area suggest that the original TAM may be more appropriate than the two-version revised TAM.

 Examining the Technology Acceptance Model Using Physician Acceptance of Telemedicine Technology   (Site not responding. Last check: 2007-11-07)
While such acceptance has received fairly extensive attention from previous research, additional efforts are needed to examine or validate existing research results, particularly those involving different technologies, user populations, and/or organizational contexts.
The model's overall fit, explanatory power, and the individual causal links that it postulates were evaluated by examining the acceptance of telemedicine technology among physicians practicing at public tertiary hospitals in Hong Kong.
The relatively low R-square of the model suggests both the limitations of the parsimonious model and the need for incorporating additional factors or integrating with other IT acceptance models in order to improve its specificity and explanatory utility in a health-care context.

The Technology Acceptance Model (TAM) is an (System consisting of the network of all communication channels used within an organization) information systems theory that models how users come to accept and use a technology.
In the context of software use, this provides a mechanism for discussing the current mix of usefulness and EOU for particular software packages, and for plotting a different course if a different mix is desired, such as the introduction of even more powerful software (Keil, Beranek & Konsynski, 1995).

New technologies with enormous and radical potentials are often "socialized" into the existing norms and practices of the organization much like the new teachers described by Hobas.
We must offer teachers adult learning experiences with the new technologies which excite them, appeal to their deepest selves and model the kinds of learning we hope to see developing as we move into the next century.
Even though technology refusal may have been rooted as Hodas claims in the nature and purposes of schooling designed for a different kind of society and economy, the technology choices offered to teachers in the past and the failure to provide appropriate adult learning opportunities may have contributed dramatically to patterns of refusal.

TAM posits relationships among the following variables: perceptions of the ease of using technology, perceptions of usefulness of technology, intentions to use technology, and actual usage behavior.
Aside from testing the proposed model, the major purpose of this research was to see how student intentions to use online technologies in their future careers were affected by the main TAM variables.
After completing the project, students’ perceptions of the usefulness of BBSs became a significant antecedent of their intentions to use BBSs in their future careers, and perceived ease-of-use became less important in terms of future career intents, apparently as a result of the project.

 Testing The Technology Acceptance Model
Abstract In recent years, the technology acceptance model (TAM) has been widely used by IS researchers in order to gain a better understanding of the adoption and use of information systems.
While TAM has been widely applied and tested in North America, there have been no attempts to extend this work to other regions of the world.
The results indicate that TAM holds for both the U.S. and Switzerland, but not for Japan, suggesting that the model may not predict technology use across all cultures.

The model proposes control (internal and external-conceptualized as computer self-efficacy and facilitating conditions respectively), intrinsic motivation (conceptualized as computer playfulness), and emotion (conceptualized as computer anxiety) as anchors that determine early perceptions about the ease of use of a new system.
The proposed model was tested in three different organizations among 246 employees using three measurements taken over a three-month period.
The proposed model was strongly supported at all points of measurement, and explained up to 60% of the variance in system-specific perceived ease of use, which is twice as much as our current understanding.
