  • Community of inquiry 普通类

    In this paper, several recent theoretical conceptions of technology-mediated education are examined and a study of 2159 online learners is presented. The study validates an instrument designed to measure teaching, social, and cognitive presence indicative of a community of learners within the community of inquiry (CoI) framework [Garrison, D. R., Anderson, T., & Archer, W. (2000). Critical inquiry in a text-based environment: Computer conferencing in higher education. The Internet and Higher Education, 2, 1–19; Garrison, D. R., Anderson, T., & Archer, W. (2001). Critical thinking, cognitive presence, and computer conferencing in distance education. American Journal of Distance Education, 15(1), 7–23]. Results indicate that the survey items cohere into interpretable factors that represent the intended constructs. Further it was determined through structural equation modeling that 70% of the variance in the online students’ levels of cognitive presence, a multivariate measure of learning, can be modeled based on their reports of their instructors’ skills in fostering teaching presence and their own abilities to establish a sense of social presence. Additional analysis identifies more details of the relationship between learner understandings of teaching and social presence and its impact on their cognitive presence. Implications for online teaching, policy, and faculty development are discussed.

  • The POD model: Using communities 普通类

    This paper focuses on the broad outcomes of a research project which aimed to analyse and model student teachers’ learning in the online components of an initial teacher education course. It begins with discussion of the methodological approach adopted for the case study, which combined conventional data gathering techniques with those which are facilitated using the ‘panoptical’ tools of the VLE. The author has synthesized case study evidence, learning theory (Community of practice theory) and the advice of a key theoretician, to produce an original model of student teachers’ learning online within a professional online district (POD). The most distinctive feature of the POD model is the learning-curriculum dichotomy which recognises the potential of a VLE as a venue in which student teachers, working together in a community of practice, construct their own curriculum (both formal and informal/’hidden’. The paper also examines the key technological and pedagogical issues which affect students’ online learning.

  • Impact of media richness 普通类

    Advances in e-learning technologies parallels a general increase in sophistication by computer users. The use of just one theory or model, such as the technology acceptance model, is no longer sufficient to study the intended use of e-learning systems. Rather, a combination of theories must be integrated in order to fully capture the complexity of e-learners, who are both system users and learners. The current research presents an integrated theoretical framework to study users’ acceptance of streaming media for e-learning. Three streams of research provide the basis for this integrated framework: the technology acceptance model, flow theory and media richness theory. Students enrolled in an online section of an information systems course used one of three different combinations of text, streamed audio and streamed video. Regression analysis was used to test the hypotheses in this field experiment. Perceived ease of use was a predictor of perceived usefulness; both the perceived usefulness and the attitude of the user were predictors of intention to use. Richer content-presentation types were positively correlated with higher concentration levels but showed mixed results when correlated with perceived usefulness. Results from this study have practical implications for those interested in integrating streaming media into e-learning.

  • Investigating university students’ adaptation 普通类

    Digital learner portfolios are of growing importance in higher education as the sector seeks new teaching–learning–assessment methods which promote students’ autonomy as managers of their own virtual learning environment. The purpose of this study was to analyse descriptively the undergraduate students’ perceptions, attitudes and behaviour when using an eportfolio to support their learning and assessment in practice based courses at two traditional Spanish universities. The participants were 88 students, who were studying through a blended learning mode. Data were collected through questionnaires: a computer experience survey, another which examined the psychological, pedagogical and technological dimensions of eportfolios use. Further, an individual overall reflection was obtained from each student to help gain an understanding of their experiences of using the eportfolio. A mixed-method analysis was applied in order to study the impact of this technological innovation on students and their satisfaction. The results showed that the students had positive opinions and self-efficiency through the eportfolio as a tool to manage their learning and assessment during a semester, especially from the second month of use. However, the expected impact on their learning was not so significant. Nevertheless, the students emphasised that the eportfolio was valuable as a personal developmental learning tool.

  • iTunes University and the classroom 普通类

    iTunes University, a website with downloadable educational podcasts, can provide students the opportunity to obtain professors’ lectures when students are unable to attend class. To determine the effectiveness of audio lectures in higher education, undergraduate general psychology students participated in one of two conditions. In the lecture condition, participants listened to a 25-min lecture given in person by a professor using PowerPoint slides. Copies of the slides were given to aid note-taking. In the podcast condition, participants received a podcast of the same lecture along with the PowerPoint handouts. Participants in both conditions were instructed to keep a running log of study time and activities used in preparing for an exam. One week from the initial session students returned to take an exam on lecture content. Results indicated that students in the podcast condition who took notes while listening to the podcast scored significantly higher than the lecture condition. The impact of mobile learning on classroom performance is discussed.

  • Negotiation of meaning 普通类

    Variations in group co-construction of knowledge and the extent to which participants engaged in negotiating meaning were directly related to instruction. The authors examined social interaction resulting from controlled variation in instruction using a counter-balanced design in two professional development courses for teachers. Both courses were held at the same time, included the same content with the same instructor, and were held in an asynchronous online format. Twenty-four subjects were randomly assigned to the two courses. Using socio-historical constructivist theory to guide instruction interventions, instruction frequency and questioning were intentionally manipulated during one-half of each course. The variations in instruction were hypothesized to promote negotiation of meaning and co-construction of knowledge within both groups. Transcript analysis using a dependent measure of social interaction was applied to the 782 utterances of the participants. Multiple comparisons revealed significant differences in the dependent measure in portions of the course where modified instructional strategies were implemented. The results show that relatively simple alterations in instructional practice (e.g., increasing instructional statements from once to twice per week and engaging participants in dialogue through open-ended questioning) yields a substantially enhanced learning outcome within this environment. Strong evidence suggests that online learning groups depend heavily on instruction to facilitate negotiation of meaning and co-construction of knowledge. This research raises concerns about whether or not instructors employ instructional strategies that influence social knowledge construction and subsequent learning outcomes from asynchronous online courses. In addition, the study demonstrates the utility of a previously published measure for social interaction in CMC.

  • Fast searching for information 普通类

    The purpose of the study was to examine the role of domain knowledge when retrieving and using information from the Internet as a resource for essay tasks, as well as to investigate the quality of Internet searches and its relation to essay performance. In two experiments, 100 undergraduates searched the Internet for 30 min and completed two essays; one in which they had high domain knowledge and one in which domain knowledge was low. Two control groups of 70 undergraduates just wrote the essays. Searching the Internet for information enhanced essay performance relative to the control groups only for the topic for which participants had high domain knowledge. In the second experiment, analyses of Internet searches revealed large individual differences in search behaviors and these behaviors did not relate to essay performance, although individuals highlighted the importance of domain knowledge in making their searches easier. Domain knowledge is one factor that educators should pay attention to when using the Internet for learning tasks, particularly when study time is limited, in order to maximize the ability of students to successfully retrieve and use information from the Internet.
