The goal of this study is to better understand how the study participants’ cognitive discourse is displayed in their learning transaction in an asynchronous, text-based conferencing environment based on Garrison’s Practical Inquiry Model (2001). The authors designed an online information ethics course based on Bloom’s taxonomy of educational objectives and Bird’s 3C model (Content–Construction–Consolidation). The content analyzed included the participants’ message posts, the quality of the dialogue and the scaffolding strategies for mentoring used by group leaders and teachers. 相似文献

e-Learning systems are increasingly being adopted by modern enterprises, because of their cost-down effect. However, the extant literature provides little insight into their beneficial consequences. It is expected that a transfer of acquired knowledge, skills and/or work attitudes to jobs will occur through e-learning systems use. This makes e-learning systems a useful tool for improving job outcomes, although this is not well documented. The IS success model, which captures both the human and technological elements of information systems, provides a theoretical basis for linking system use to system task. The current study then examines the relation between e-learning systems use and overall job outcomes based on the model. The data collected from one hundred and ninety-three e-learning system users were analyzed with partial least square (PLS). The results indicate that e-learning systems are perceived as useful and satisfying by employees, and employees’ e-learning systems use is significantly associated with overall job outcomes. In practice, these results provide a basis for establishing a link between an organization’s investment in e-learning and human capital management. They also lend empirical support to the IS success model. 相似文献

This paper reports on a pilot investigation into web conferencing in a distance learning module. It focuses on the perceptions and experiences of the tutors, all of whom were new to the web conferencing environment, but were experienced in online teaching. A number of web conferencing tutorials were studied through the collection of various datasets, mostly qualitative. The data were analysed by a team of researchers, informed by key literature in this area.The main findings from the pilot indicated that tutors experienced challenges in creating social presence and in managing cognitive load when dealing with multiple tasks online. There were also technical obstacles to improvisation in response to students’ emerging needs. The findings of the pilot informed the training and support provided when web tutorials were subsequently rolled out to all tutorial groups (approximately 140) in the module. Overall, experiences from the web tutorials indicate that tutors and students reacted positively to the opportunities web conferencing provides for interactive learning and teaching. 相似文献

Learners’ satisfaction and persistence are considered critical success factors in online universities where all of the teaching and learning activities are carried out online. This study aims to investigate the structural relationships among perceived level of presence, perceived usefulness and ease of use of the online learning tools, learner satisfaction and persistence in an online university located in South Korea. The specific predictors were teaching presence, social presence, cognitive presence, and perceived usefulness and ease of use. Structural equation modeling (SEM) was used to provide cause-and-effect inferences. The study participants were 709 learners who enrolled in a Korean online university in 2009 and responded to online surveys. The results indicated that teaching presence, cognitive presence, and perceived usefulness and ease of use were significant predictors of learner satisfaction, which was found to be a significant mediator of predictors and persistence. The findings provided substantial implications for designing and implementing teaching and learning strategies in online university environments. 相似文献

This research study looks at how organizations in developing countries perceive the challenge of building capacity in e-learning expertise. Data was collected on six such organizations, and a range of perceived rationales and constraints were identified. The paper hypothesizes a four-part framework to define the e-learning capacity gaps that these circumstances appear to represent: the “instructional design capacity gap”, the “production capacity gap”, the “tutorial capacity gap” and the “community building gap”. The framework is used to re-examine the data to explore the ways in which the organizations’ e-learning activities might constitute strategic responses to the hypothesized capacity gaps. 相似文献

The popularity of today’s blended courses in higher education is driven by the assumption that students are provided with a rich toolset that supports them in their learning process. However, little is known on how students actually use these tools and how this affects their performance for the course. The current study investigates how students use the entire toolset at their disposal, whether tool-use patterns can be found and if these patterns affect performance for the course. Logging students (n = 156) actions throughout the content management system and registering students’ use of the face-to-face support in an undergraduate course, the study reveals large student differences and an underuse for some tool-types. Further to this, K-means cluster analysis reveals three distinct tool-use patterns or user profiles: the no-users, the intensive users and the incoherent users. These patterns are characterized by different tool-choices and even different use intensity among students. Evidence is retrieved that these tool-use differences are problematic since multivariate analysis of variance reveals significant performance effects. Hence, these results imply that not all students seem to profit from the learning affordances that are provided. Similar as evidence in controlled settings, the results suggest that learner control in using tools cannot be taken for granted. Consequently, this study legitimates more research into the influencing (student and context) variables that can explain these differences. 相似文献

Reflection plays an important role in improving learning performance. This study, therefore, attempted to explore whether learners’ reflection levels can be improved if teaching strategies are adapted to fit with learners’ thinking styles in an online learning environment. Three teaching strategies, namely constructive, guiding, and inductive, were designed to match with three thinking styles, namely legislative, executive, and judicial respectively. An online reflection learning system was subsequently developed to reflect this scenario. An experiment was then conducted where the learners were classified into fit or non-fit group in order to analyze whether there was a good fit between the teaching strategies designed by the teacher and the thinking styles of learners. A total of 223 graduate and undergraduate students participated in the experiment. The results revealed that the reflection levels of the fit group had outperformed the non-fit group. 相似文献

The academic e-learning practice has to deal with various participation patterns and types of online learners with different support needs. The online instructors are challenged to recognize these and react accordingly. Among the participation patterns, special attention is requested by dropouts, which can perturbate online collaboration. Therefore we are in search of a method of early identification of participation patterns and prediction of dropouts. To do this, we use a quantitative view of participation that takes into account only observable variables. On this background we identify in a field study the participation indicators that are relevant for the course completion, i.e. produce significant differences between the completion and dropout sub-groups. Further we identify through cluster analysis four participation patterns with different support needs. One of them is the dropout cluster that could be predicted with an accuracy of nearly 80%. As a practical consequence, this study recommends a simple, easy-to-implement prediction method for dropouts, which can improve online teaching. As a theoretical consequence, we underline the role of the course didactics for the definition of participation, and call for refining previous attrition models. 相似文献

Two different technologies, groupware (a shared workspace) and shared wireless laptop computers, were implemented in a project design class in a civil engineering course. The research interest was in the way these technologies supported resource sharing within and across project groups and in the forms of group collaboration that resulted. The initiative was evaluated using both qualitative (e.g. pyramid discussion) and quantitative methods (e.g. survey, logs of usage). The results showed that these technologies helped improve group sharing of resources and supported different kinds of group collaboration. The shared workspace provided a location-independent central repository of resources around which group activities were coordinated whereas the laptops provided a focal point for the face-to-face discussion of these resources. The paper discusses the importance of embedding supportive technologies and the different forms of learner collaboration mediated by each technology. 相似文献

This study investigates the perceived barriers to adopting information and communication technologies (ICT) in Omani higher education. One hundred faculty members from four different departments at the College of Applied Sciences in Oman participated in the study. The participants took a survey, which was developed based on the Western literature. Five factors were extracted from the survey: lack of equipment, lack of institutional support, disbelief of ICT benefits, lack of confidence, and lack of time. The findings showed that the faculty members perceived moderate degrees of barriers in applying ICT to their teaching practices. Group differences based on gender, academic rank, and academic field were generally not found except for the interaction effects on the barriers related to lack of equipment, disbelief of ICT benefits, and the overall mean. Male faculty members with less usage of ICT perceived more barriers regarding the lack of computing equipment, disbeliefs of ICT benefits, and the overall barrier than the female counterparts. It is recommended that the survey be further refined to include more subtle and culturally relevant items, larger sample sizes, and more heterogeneous samples to validate and extend the findings. Important implications of this study include a need to provide more institutional support, technical training, and personal time for faculty members to learn and upgrade their knowledge and skills in educational technologies. 相似文献

As more and more people use computers to complete their work and solve problems in the workplace, computing education is emphasized for students of all levels and disciplines in Taiwan. However, the computing education in Taiwan can hardly be recognized as effective and satisfactory. Many inappropriate examples that lack context are used in teaching and textbooks that may result in employees with low competence and insufficient ability for collaborative working. Students who grow up in this learning context usually lack the ability to seek information and solve problems by themselves. In this regard, the author redesigned a course and adopted online collaborative learning with initiation to establish the essential knowledge for students’ collaboration in the initial stage of a course. This study conducted an experiment that included 169 undergraduates from three class sections – the first two from an academic university (Case 1, n = 68; Case 2, n = 68) and the last one from a university of science and technology (Case 3, n = 33) – taught by the same teacher under the same course name and the same course website. The results show that students who received online collaborative learning with initiation had higher grades than those without. The author further discusses the implications for teachers, schools, and scholars who plan to provide online courses for their students, particularly computing courses. 相似文献

“Join a Meetup Group” (face-to-face study group) has been propagated by Coursera to build rapport and provide mutual support among MOOC learners; however, studies remain scant regarding its effectiveness and sustainability. This interpretive case study documents our facilitation process, key influential factors, as well as student perceived gains in a six-week MOOC study group. Data sources include discussion recordings, end-of-course interviews, goal setting sheets, weekly reflection journals, and researchers' observation notes. Results showed that, cognitively, participants broadened their perspective of thinking, raised cultural awareness, and shared many learning strategies. Affectively, they established a strong sense of community and gained motivation for learning. Participants also increased action tendencies toward trying out Coursera functions, new courses, and learning strategies, and they became more cognizant of the benefits and procedures of the MOOC study group. Our findings suggest that, with proper design and facilitation, face-to-face study group would be a practicable and effective approach to leverage MOOC students' motivation, engagement, and deeper learning. Implications are discussed in terms of potential gains, challenges, key influential factors, as well as future design and implementation of MOOC study groups. 相似文献

We designed an e-learning model to promote critical thinking about basic science topics in online communities of students during work placements in higher education. To determine the effectiveness and efficiency of the model we explored the online discussions in two case studies. We evaluated the quantity of the interactions by looking at quantitative data of the discussion ‘threads’ and we evaluated the quality of the discussion by content analysis of the individual messages. Both the procedural facilitation of the discussion and the instrument for content analysis were based on Garrison’s ‘Practical Inquiry model of Cognitive Presence’. Furthermore, we explored the experiences of the students and moderators by interviewing them and we organised their perceptions using the framework of an activity system. On the basis of the quantitative and qualitative data we conclude that the e-learning model was successful in establishing a dialogue among a group of students and an expert during work placements at different locations. The ‘Practical Inquiry model’ was useful in facilitating a sustained on-topic discourse involving critical thinking. Although the amount of critical thinking was moderate, the results suggest ways to increase integration and resolution activities in the online discussions. 相似文献

This study examines the extent to which epistemological, motivational, decision-related, and demographic variables predict college students' use of online information searching strategies (behavioural, procedural, and metacognitive strategies). The participants included preservice teachers (N = 538) from 13 universities in different parts of Turkey. Stepwise multiple regression analyses were conducted to identify the variables predicting each online information searching strategy. The results revealed that online information searching strategies were best predicted by epistemological beliefs and then decision-making styles, web search experience, and goal orientations. Students who had advanced epistemological beliefs in speed of learning tended to have better behavioural, procedural, and metacognitive strategies, while students having naive epistemological beliefs in ability to learn had lower level online searching strategies. Students having more web search experience had better online searching strategies. Additionally, as the level of students’ mastery-approach goals increases, the use of procedural and metacognitive domain strategies increase as well, while the increase in the level of mastery-avoidance goals were related to the use of less behavioural domain strategies. Finally, students having rational decision styles were more likely to use higher levels of online information searching strategies, while students with avoidant styles tended to use less behavioural and procedural domain strategies. 相似文献

This study aims to investigate how interactivity influence learners' use of interactive functions in the course-management system (CMS) and their online learning performance. A two-tier mediation framework is proposed to examine the mediating effects of different actual-use records concerning the CMS's interactive functions. Data are collected from 381 undergraduate students who enrolled in a general-education asynchronous online course from three universities in Taiwan. The results indicate that the relationships among students' self-reported use of interactive functions, students' perceptions of the usefulness of interactive functions, and students' actual-use logs have some direct influences on students' online learning performance (online-discussion scores, exam scores, and group-project scores). In addition, students' actual-use logs (the number of times of log-ins to the online course, the number of times students read learning materials, and the number of postings on the discussion board) have a mediated effect on students' self-reported frequency of logging into the CMS, students' self-reported frequency of using the learner–instructor/learner–learner interactive functions, and online learning performance. The findings and implications could constitute a useful guide for educational practitioners and designers concerned with the effective integration of interactivity into future online courses. 相似文献

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. 相似文献

This study compared the impact of three different facilitation approaches on elementary teacher candidates’ interactions in an asynchronous discussion board as well as their satisfaction with an online educational technology course. These participants were enrolled in three different sections of the same online course. In the first section (Group 1), the instructor responded to each student’s initial message regarding the discussion question and then required students to respond to at least two of their classmates’ postings. In the second section (Group 2), the instructor responded to each student’s initial message to the discussion question, but did not require students to respond to other classmates’ postings. Instead, it was the student’s voluntary choice. In the third group (Group 3), the instructor did not respond to each student’s initial message on the discussion question, but required students to respond to at least two classmates’ postings. Data were analyzed both quantitatively and qualitatively, by using ANOVA, social networking analysis (SNA) and content analysis. The results indicated that in Group 2, voluntary interactions among students rarely occurred, resulting in the instructor primarily providing feedback to the students, with a low number of cues for social presence. In comparing Groups 1 and 3, when students were required to respond to one another, too much instructor intervention did not lead to more interactions among the students. Rather, when the instructor’s intervention was minimal, students tended to more freely express their thoughts and opinions, with a large number of cues for social presence. However, more interactions among students, occurring in a required setting, may not have correlated with student satisfaction with the online course ratings and the instructors’ ratings. 相似文献

The need to improve the quality of higher education has fostered an interest in technology tools to support effective design for teaching and learning. Over the past decade this interest has led to the development of tools to support the creation of online learning experiences, specifications to underpin design systems, and repositories to share examples. Despite this significant activity, there remain unanswered questions about what shapes university teachers' design decisions and how tools can best support their design processes. This paper presents findings from a study of university teachers' design practices that identified teachers' perceptions of student characteristics, their own beliefs and experiences, and contextual factors as key influences on design decisions. The findings extend our understanding of activities fundamental to higher education teaching and inform thinking about design support tools. 相似文献
