Many organisations and institutions have integrated learning objects into their e-learning systems to make the instructional resources more efficient. Like any other information systems, this trend has made user acceptance of learning objects an increasingly critical issue as a high level of learner satisfaction and acceptance reflects that the users are more willing to continue to use the technology. In this study, an extended version of technology acceptance model (TAM) with two external variables (learning object characteristics and individual differences) was developed to investigate the underlying factors and causal relationships in predicting learners' acceptance of learning objects. This study called for the respondents to progress through two phases of learning object participation: introduction and direct-use experience to investigate the students' perceptions in terms of usefulness and ease of use while utilising learning objects. The findings show that both perceived usefulness and perceived ease of use are determinants of behavioural intention to use learning objects. Learning object characteristics influence both perceived usefulness and perceived ease of use of learning objects; individual differences appear to have no influence upon intention to use learning objects. 相似文献

The purpose of this study was to investigate the decisions of civil servants to use Web 2.0 applications while engaging in online learning. The participants were 439 civil servants enrolled in asynchronous online learning programs, using an e-learning portal provided by Taiwan's Regional Civil Service Development Institute. The participants completed a questionnaire which measured their responses to 12 constructs (perceived usefulness, perceived ease of use, compatibility, peer influence, superior influence, self-efficacy, facilitating conditions, attitude, subjective norm, perceived behavior control, behavior intention, and behavior) based on the decomposed theory of planned behavior. The research results revealed that the participants’ perceived usefulness of online learning was the strongest predictor affecting their attitude. Peer influence was also the primary factor influencing their subjective norm. The construct of self-efficacy appeared to be the most important element determining their perceived behavioral control. Also, the results of the path analysis showed that the participants’ attitude was the strongest indicator of their behavior intention to use Web 2.0 applications, followed by the perceived behavior control and subjective norm. Theoretical and practical implications and recommendations are provided based on the results of the study. 相似文献

This large scale study investigated the influences that technology-related policies and teachers’ constructivist teaching beliefs have on their intention to use technology in Chinese universities. Data were collected from 696 English teachers working in 59 Chinese universities. Five variables (subjective norm, constructivist teaching belief, perceived importance of policy, computer self-efficacy and voluntariness) were examined in this study. Results indicated that perceived importance of policy, constructivist teaching beliefs and subjective norm were significant antecedents of perceived usefulness. The relationship between subjective norm and teachers’ intentions to use technology was moderated by voluntariness. Besides perceived usefulness, perceived ease of use also had significantly influenced English teachers’ behavioural intention. Overall, the research model explained 69% of variance of teachers’ intentions to use technology. This study has the potential to enrich our understanding of technology acceptance in teaching by contextualising the study in the rarely researched English teaching context in Chinese universities. The findings from this study also provide suggestions for policy makers and teacher educators. 相似文献

Offering an online integrated high-school course or subject for the first time involves many challenges. Better understanding the factors that affect students’ willingness to participate in the experience could provide support for better implementation of such a strategic initiative. In addition, it is important to understand how personal factors can influence the success of such an endeavour. This study develops a comprehensive structural equation model that captures most causal factors related to offering a high-school course online for the first time. A sample of public and private secondary school students (Grades 10, 11 and 12) in Abu Dhabi were administered an online survey regarding offering free online courses. The instrument was reviewed by other experts in curriculum, information technology and teaching and learning. The final instrument contained dimensions related to student perception of ease of use of e-learning, usefulness, self-efficacy, skills, style, student self-reported performance in certain subjects, use of social media, school support, teacher support, general support, access to the internet, and preferences behavioural intentions to use e-learning. The analysis provides a structural equation model with acceptable statistical fits and with many significant causal relationships. The paths representing direct and indirect effects of the construct predictors on intention to use provided statistical evidence of the validity of the 13 component predictors. Results show significant links between intention to use e-learning, perception of easiness, perception of usefulness, and other factors such as user characteristics and support. Use of social network affect intention to use e-learning indirectly thorough other variables. Limitations and implications of the study in general and as it concerns Abu Dhabi are highlighted. 相似文献

ABSTRACTAbundant health knowledge resources are available on social media to facilitate technology-enhanced knowledge learning among older adults. The objective of this study is to investigate the predictors and the underlying formation mechanism of older adults’ intention to learn health knowledge on social media. We propose a novel model to examine how older adults’ emotional state (i.e., health anxiety) and cognitive state (i.e., e-health literacy) during knowledge acquisition influence threat appraisal (i.e. perceived severity and perceived susceptibility) and coping appraisal (i.e. self-efficacy and perceived benefits), thereby shaping older adults’ intention to learn health knowledge. Survey data from 337 Chinese older adult users of social media was collected to test the research model. Results reveal that perceived susceptibility, self-efficacy and perceived benefits exert positive effects on older adults’ health knowledge learning intention, while the impact of perceived severity on health knowledge learning intention is not statistically significant; health anxiety is positively correlated with perceived severity and perceived susceptibility, and e-health literacy is a powerful predictor of self-efficacy and perceived benefits. This paper enriches the literature related to technology-enhanced knowledge learning and online health behavior among older adults. Effective strategies are proposed based on the findings for practitioners dedicated to promoting health knowledge via social media and older adults who apply health knowledge to address health-related needs. 相似文献

AbstractThe aim of this paper is to analyze the impact of trust perceptions on teachers’ intention to continue using e-learning technology in higher education. Drawing on the model of organizational trust and the information systems continuance model, a new research model is developed and tested using data from a university college based on a survey of 401 university teachers. We find that teachers’ perceptions of system-based trust and trust in management exerted strong direct effects on intention to continue using an e-learning system. Additionally, system-based trust affects perceived usefulness, and thus fully mediates the influence of perceived usefulness on teachers’ intentions to use e-learning technology. Our findings clarify the relationship between trust and teachers continued use of e-learning technology and have implications, theoretical as well as practical, for trust-building structures that could improve the implementation of e-learning technologies in higher educational settings. 相似文献

Pedagogical beliefs are a critical factor in terms of integrating technology into teaching, but very few technology acceptance models (TAMs) have considered them. Hence, this study aims to extend the TAM by incorporating pre-service teachers’ conception of teaching and learning. The revised model examined the influence of pre-service mathematics teachers’ constructivist and traditional pedagogical beliefs on their technology acceptance through perceived ease of use, perceived usefulness, attitude toward technology, and behavioral intention to use. Survey data were collected from 714 pre-service mathematics teachers in Turkey and analyzed through path analysis. The results showed that pre-service mathematics teachers’ pedagogical beliefs were more constructivist-oriented than traditional-oriented, and constructivist beliefs had a significant influence on the components of the TAM. On the other hand, pre-service teachers’ traditional-oriented beliefs did not influence their perceived usefulness of and attitudes toward technology but had positive effects on perceived ease of use. Implications for pre-service mathematics teacher education were discussed.

AbstractResearch databases are a significant contributing aspect of modern technology, and, as such, innovation has enhanced learning and research outputs using online databases introduced by authorities in charge of higher education. However, databases have been rarely investigated from the perspective of psychological assessment. Therefore, this research examined databases using structural equation modelling and the Rasch model to explore contributing factors of learning and research in higher education. To measure databases, this research adapted the online database adoption and satisfaction (ODAS) model and analysed the responses of 300 postgraduate students, from a double first class university in Shanghai, collected using a stratified random sample technique. The results of the ODAS model showed that the postgraduate students’ perceived usefulness and ease of use of databases played mediating roles in establishing connections between their computer self-efficacy and intention to use and satisfaction with databases for research and learning. However, the ODAS model also showed that the students’ satisfaction was indirectly explained by their perceived usefulness of databases through ease of use and intention to use. The results of our investigation contribute to a better understanding of the ODAS model and suggest assessment strategies for learning and research through databases for researchers, academicians, and librarians. 相似文献

The study was grounded on theoretical propositions and empirical research concerning school effectiveness, classroom effectiveness, school improvement and school renewal. In particular, improving student learning outcomes through improving and renewing schools is dependent on changing classroom cultures of learning and teaching. A model of classroom culture consisting of student educational values (dependent variable), formal learning outcomes (dependent variable), and the attitudes and behaviours of students, teachers and parents (independent variables) was proposed. Hypothesised relationships between the dependent and independent variables were tested by multiple regression analysis of data from 988 students obtained from administration of a Rasch-model instrument assessing classroom culture. The classroom learning attitudes and behaviours of students were found to relate directly to educational outcomes, as were teacher expectations and parent attitudes and behaviours. The attitudes and behaviours of students and teachers towards classroom collaboration and caring were not confirmed to relate directly to learning outcomes. The findings of the investigation are discussed in the light of the theoretical assumptions upon which the study was based, including identification of the implications of the empirical results for understanding and facilitating renewal of secondary schools with the intention of improving educational outcomes in classrooms. 相似文献

Drawing from social resource-social capital theory, this paper aims to clarify and characterize the role of harmonious learner–instructor and learner–learner relationships in promoting experience and retaining learners in online learning environments. Hypotheses are tested by applying a structural equation model and the data are collected from a survey of online learning website (n?=?539). The results suggest that harmonious relationships have a positive impact on learners’ experience (i.e. perceived performance, enjoyment and social presence), which, in turn, strengthen learners’ continuous intention to use the e-learning platform. And learners’ expertise moderates the relationships between harmonious relationships and learner experience. Based on the analysis results, this study can provide educational institutions with useful tactics to retain learners in the e-learning environments. 相似文献

ABSTRACTLearning outcomes is mediated by multi-channel learning environment and social engagement. Both factors may play a significant role in understanding motivation to learn in massive open online courses (MOOCs). The goal of this study was twofold: a. to compare behavior intention patterns of traditional e-learning platform and MOOCs participants; b. to examine relationships between behavior intention and perceived social support. Therefore, this study applies the concepts of technology acceptance model and social support theory to examine the underlying the determinants of learners’ continuance intention factors for MOOCs in Taiwan. In addition, this study adopts perceived convenience, computer self-efficacy, sense of community, and perceived gains as the constructs of social support perspective. Our examination reveals that sense of community, and perceived gains influence learners’ behavior intention of both general e-learning platform and MOOCs. However, perceived convenience and computer self-efficacy did not influence learners’ behavior intention for traditional e-learning platform, but still have efforts for MOOCs. In summary, our results show that the social support theory and technology acceptance model could be the suitable examination model to investigate the behavioral intentions for MOOCs. These findings have significant theoretical and managerial implications. 相似文献

Given the paradox between pervasive promotion of technology use in English teaching and lack of studies about teachers’ technology acceptance in China, this study aims to examine intentions of English teachers in China to use technology in their classroom teaching. Based on the technology acceptance model, eight variables including perceived usefulness (PU), perceived ease of use (PEU), attitude toward use, behavioral intention (BI), computer self-efficacy (CSE), technology complexity (TC), facilitating conditions (FC), and constructivist teaching beliefs (CTBs) were incorporated to examine relationships among these variables. Data were collected from 183 English teachers at 5 Chinese universities via a self-report questionnaire and analyzed using a structural equation model. Results indicated that the proposed model has a good fit. Three variables – PU, FC, and CTBs were found to be significant predictors of attitude toward use, while PEU and TC were not. Additionally, PU, CSE, and CTBs are significant antecedents for teachers’ BIs to use technology. This study contributed to the understanding of technology acceptance theories by contextualizing the current study to Chinese educational context. It also provided valuable references for technology-related policy-making and teachers’ professional development. 相似文献

This study aims to analyse the factors that can explain the adoption and effective use of a new e-learning system in Iraq. To achieve this, it uses a selection of factors that are present in the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT) model, and it includes three additional factors. The study hypothesises new relationships between the selected factors. Questionnaires were distributed to 300 university students in Iraq. Partial least squares-structural equation modelling (PLS-SEM) was used to analyse the data received. The findings suggest that perceived usefulness (PU), perceived ease of use (PEOU), subjective norms (SNs), information quality (IQ), system quality (SQ), technical support (TS) and self-efficacy (SE) have significant effects on behavioural intention (BI). In turn, BI and TS have significant direct effects on the actual use (AU) of e-learning systems. The factors age, gender and experience significantly moderated some of the relationships in the model. The research has several implications for policy makers, universities and the management of e-learning systems. 相似文献
