For many instructors in higher education, use of a learning management system (LMS) is de facto mandatory. Nevertheless, instructors often have much freedom in deciding which functionalities of the LMS they use; that is, whether they perform each individual instructor task using the LMS. Alternatively, they may perform one specific instructor task using alternative means, or, quite often, not perform it at all. The current Technology Acceptance model (TAM) fails to describe this decision process accurately, as TAM (1) does not focus on the level of the individual task; (2) does not make a distinction between not performing a task and performing a task using alternative means; and (3) does not recognize one important factor that affects the performance of a specific task—task importance. A test of three different models shows that the decision process is best represented as a two-step process. First, influenced by task importance, a choice is made to either perform a specific task or not. Second, after the decision has been made to perform the task, and influenced by the usefulness and ease of use of the LMS, a choice is made between performing the task using the LMS and using alternative means.  相似文献

The most important factor in the decision to adopt mobile systems is user perception of their value. However, behavioral theory suggests that context affects user attitude and therefore influences acceptance. We therefore hypothesized that the benefits of mobile systems should be evaluated against users’ contextual needs and that reduced dependence on time and place required providing service at any time and place needed by the user. Mental costs or costs of learning to use the system, however, may not be evaluated in the same way, because system use and learning about it are acts with different contexts. Our findings advance knowledge of IT adoption and suggest that we should start to identify the contexts of both the benefits of use and in learning to use the system.  相似文献

Research on elderly people's ICT acceptance and use often relies on the technology acceptance model (TAM) framework, but has been mostly limited to task-oriented uses. This article expands approaches in technology acceptance and use by developing a model to explain entertainment-related uses of new media technology by elderly people. On a theoretical level, we expand the TAM perspective by adding concepts that act as barriers and/or facilitators of technology acceptance, namely technophobia, self-efficacy and previous experience and expertise with technology. We develop an expanded TAM by testing the role of these concepts in two studies on entertainment media technology. In Study 1, we investigate behavioural intention to use 3D cinema among N?=?125 German elderly media users (Age 50+). In Study 2, we focus the actual use of a computer game simulation by N?=?115 German and US elderly media users (Age 50+). Findings in both studies point towards the central role of perceived usefulness, here modelled as enjoyment, as the reason for elderly people's use and acceptance of entertainment media technology. Perceived ease of use is seen as a precondition for enjoyment, particularly for interactive media.  相似文献

The worldwide growth of mobile technology has enabled many companies to take advantage of its application as complementary sales tools. The main objective of this research is user acceptance analysis of near field communication mobile payment systems. Classic variables from the technology acceptance model, as well as variables from other recent studies, were used as models for this research (compatibility, security, personal innovation and individual mobility). To meet these objectives a questionnaire, filled out by 191 respondents, formed the basis of a structural equation modeling designed by PLS 3.0 software. The results show that attitude, subjective norms and innovation and are determinants of the future intention to use this technology. Finally, the main implications for corporate management and business development strategies which reinforce this type of business in light of new technical developments are discussed.  相似文献

The problem described in this research is to identify which factors influence on engineering students about their acceptance of an academic administrative information system in private universities in Lima, Peru. The objective is to identify factors by proposing a Technology Acceptance Model of an Academic and Administrative Information System. University population is described, both private and public. The investigation is based on two private universities. The results show the relationship between the selected variables. Finally, recommendations are given to act on the variables that determine the acceptance of information technology.  相似文献

In spite of many theoretical models, the role of exogenous factors in accepting object-oriented technology has not been satisfactorily demonstrated. By comparing two competing models, our study examined the role and location of exogenous variables in explaining user acceptance of object-oriented technology. Based on the results, we developed a new model that combined the key ideas of both TAM and TPB and showed that both models are necessary in understanding the unique role of each exogenous variable.  相似文献

Desk design and computer display height can affect posture and muscle activation during computer use. Amplitudes of postural variables and muscle activity during computer use do not explain the results from epidemiological studies of musculoskeletal discomfort and disorders related to computer use. The purpose of this study was to assess variability of posture and muscle activity during work with two computer display heights and book/paper, in conjunction with a curved desk designed to provide forearm support and a traditional, straight desk.18 male and 18 female participants performed 10-min tasks involving keying, mousing, reading and writing in six desk/display conditions. 3D posture and surface emg were assessed for the final 2 min of each task.The curved desk resulted in greater postural and muscle activity variation, suggesting an advantage of this supportive surface over the straight desk. There was little difference in variability associated with the two display heights. However, greater variability of posture and muscle activity was evident with the book/paper condition. Non-touch typists had greater neck flexion variation.The design of information technology tasks and workstations can influence the short term variation in posture and muscle activity. Variation is influenced independently of mean postures and muscle amplitudes and therefore needs to be considered to adequately assess the risk of musculoskeletal disorders.  相似文献

The preponderance of poor people worldwide live in rural areas. Since they cannot afford, and are not educated sufficiently to take full advantage of contemporary knowledge-based technologies, alternative approaches are necessary. A major business model to do so involves setting up a rural telecenter that provides computer and internet technology as a shared model or highly subsidized. Despite the potential and availability of telecenters, research suggests that telecenters have low usage. In this research, we explore the reasons for the low usage of telecenters using a framework for use and acceptance of rural telecenters. The framework we use builds on prominent IT theories and has the following four dimensions: (a) perceived outcomes, (b) perceived effort, (c) social influence, and (d) facilitating factors. We use this framework to formulate six research questions. The study in general has the goal to identify reasons for low use of telecenters and test it with an exploratory study of information and communication technology users and non-users from rural India. Implications are discussed at the village and provider levels. Ramiro Montealegre is the accepting Associate Editor for this article. View all notes  相似文献

Purpose of this research is to explain the factors affecting high school teachers' acceptance and use of interactive whiteboard within the scope of FATIH project according to the Unified theory of acceptance and use of technology (UTAUT, Venkatesh et al., 2003). The study was designed using causal research design in order to examine the cause-effect relationship between the variables. Sample of the study consists of 158 teachers, determined via criteria sampling, who have participated in the study voluntarily. Data has been collected using a 7 points Likert scale, developed for this study, which covers UTAUS's factors and variables featuring interactive whiteboard acceptance and use of the teachers. The collected data has been analyzed with simple and multiple linear regressions and structural equation model. The findings have shown that performance expectancy, effort expectancy and social influence had positive effects on behavioral intention; behavioral intention and facilitating conditions had positive effects on the usage time of interactive whiteboard.  相似文献

Information retrieval models are reviewed from the viewpoint of retrieval needs that cause different types of retrieval tasks. A generalized iterative query-response scheme of the retrieval process is presented. The characteristics of the system of retrieval mechanism models aimed at the support of retrieval tasks of different types, as well as at the development of the retrieval process using internal and external feedback, are stated. The use of models of multidimensional quantitative analysis based on coordinate indexing to perform external feedback is proposed.  相似文献

The unified theory of acceptance and use of technology (UTAUT), a model of the user acceptance of IT, synthesizes elements from several prevailing user acceptance models. It has been credited with explaining a larger proportion of the variance of ‘intention to use’ and ‘usage behavior’ than do preceding models. However, it has not been validated in non-Western cultures. Using a survey sample collected from 722 knowledge workers using desktop computer applications on a voluntary basis in Saudi Arabia, we examined the relative power of a modified version of UTAUT in determining ‘intention to use’ and ‘usage behavior’. We found that the model explained 39.1% of intention to use variance, and 42.1% of usage variance. In addition, drawing on the theory of cultural dimensions, we hypothesized and tested the similarities and differences between the North American and Saudi validations of UTAUT in terms of cultural differences that affected the organizational acceptance of IT in the two societies.  相似文献

TAM specifies a pathway of technology acceptance, from external variables to beliefs, attitudes, and system usage. We tested one of its assumptions that the ‘perceived ease-of-use’ and ‘perceived usefulness’ constructs fully mediate the influence of external variables on usage behaviors. Using a survey of 125 employees of a U.S. Government agency we found, contrary to the normally accepted assumption, that external variables could have direct effects on usage behavior over and above their indirect effects. We also found that TAM is significantly and consistently better at predicting frequency than volume of usage.  相似文献

Prior studies have focused on general technology use and technology use in domain-general applications and quantity of technology use. Recent evidence suggests that investigations should consider how technology is used in more contextually specific ways, including how technology is used for various cognitive tasks in specific classrooms. The purpose of this study was to examine the ways in which classroom content area and student goal orientation have a coordinated influence for how students used technology to support learning. The sample included high school students in a Midwestern state who were surveyed on their motivation and how they used technology to support learning. The study employed hierarchical linear modelling to examine how goal orientation and classroom content area predicted various levels of Bloom's Digital Taxonomy. Students who adopted mastery-oriented goals were more likely to use technology for various cognitive tasks, especially those at higher levels of complexity. Lastly, the association between mastery goal orientation and some aspects of technology use was conditioned on content area, although effect sizes were small. This study showed that, overall, technology is used differentially across four core content areas. Students in mathematics classrooms used technology less, however much of technology use was evident at lower cognitive levels. Second, students' goal orientation, and in particular their mastery goals influence how technology is used across content areas, and this is marginally conditioned on content area. Technology use should match the instructional context to maximize technology use and students' goal orientation.  相似文献

Derived from the theory of reasoned action, the technology acceptance model (TAM) focuses on two specific salient beliefs—ease of use and usefulness. It has been applied in the study of user adoption of different technologies, and has emerged as a reliable and robust model. However, this has not discouraged researchers from incorporating additional constructs to the original model in their quest for increased predictive power. Here, an attempt is made in the context of explaining consumer intention to use on-line shopping. Besides ease of use and usefulness, compatibility, privacy, security, normative beliefs, and self- efficacy are included in an augmented TAM. A test of this model, with data collected from 281 consumers, show support for seven of nine research hypotheses. Specifically, compatibility, usefulness, ease of use, and security were found to be significant predictors of attitude towards on-line shopping, but privacy was not. Further, intention to use on-line shopping was strongly influenced by attitude toward on-line shopping, normative beliefs, and self-efficacy.  相似文献

Social network sites provide the opportunity for building and maintaining online social network groups around a specific interest. Despite the increasing use of social networks in higher education, little previous research has studied their impacts on student's engagement and on their perceived educational outcomes. This research investigates the impact of instructors' self-disclosure and use of humor via course-based social networks as well as their credibility, and the moderating impact of time spent in these course-based social networks, on the students' engagement in course-based social networks. The research provides a theoretical viewpoint, supported by empirical evidence, on the impact of students' engagement in course-based social networks on their perceived educational outcomes. The findings suggest that instructors who create course-based online social networks to communicate with their students can increase their engagement, motivation, and satisfaction. We conclude the paper by suggesting the theoretical implications for the study and by providing strategies for instructors to adjust their activities in order to succeed in improving their students' engagement and educational outcomes.  相似文献

Along with increasing investments in new technologies, user technology acceptance becomes a frequently studied topic in the information systems discipline. The last two decades have seen user acceptance models being proposed, tested, refined, extended and unified. These models have contributed to our understanding of user technology acceptance factors and their relationships. Yet they have also presented two limitations: the relatively low explanatory power and inconsistent influences of the factors across studies. Several researchers have recently started to examine the potential moderating effects that may overcome these limitations. However, studies in this direction are far from being conclusive. This study attempts to provide a systematic analysis of the explanatory and situational limitations of existing technology acceptance studies. Ten moderating factors are identified and categorized into three groups: organizational factors, technological factors and individual factors. An integrative model is subsequently established, followed by corresponding propositions pertaining to the moderating factors.  相似文献

The purpose of this paper is to discuss how various factors intertwine to affect Chinese older adults’ decisions to adopt the Internet by applying the expanded technology acceptance model (TAM). Perceived usefulness (PU), perceived ease of use (PEU), subjective norm (SN), and facilitating conditions (FC) were four key predictors. Gender and age were included in the proposed model as factors to moderate the effect of two key TAM components (PU and PEU) on adoption behaviors. The results indicate that PU, PEU, and SN were significant predictors of Internet adoption among Chinese older adults, while PU, SN, and FC were significant predictors of Internet use intention. The effect of PEU on Internet use intention was also found to be stronger for older seniors than younger seniors. Implications for future research and practices are discussed.  相似文献

This research represents a theoretical extension of the Technology Acceptance Model (TAM), which IS researchers have used to explain technologies’ perceived usefulness and individuals intention to use it. The authors developed a model, referred to as the Mobile Wireless Technology Acceptance Model (MWTAM), to test the relationship between theoretical constructs spanning technological influence processes (Perceived Ubiquity, and Perceived Reachability) and cognitive influence processes (Job Relevance, Perceived Usefulness, and Perceived Ease of Use) and their impact on Behavioral Intention. MWTAM is assessed using data collected from an online survey and analyzed using AMOS 5.0. Results provide evidence to support MWTAM as both the technological and cognitive influence processes accounted for 58.7% of the variance explained in an individual’s Behavioral Intention toward using mobile wireless technology. Additionally, the path coefficients between constructs ranged from 0.241 to 0.572 providing further evidence to support the theoretical extension of TAM.
