Discussion forums are increasingly central to massive open online courses (MOOCs), and it is vital for learners to participate in associated forum activities. Active forum participation positively relates to learner achievement in that more posts yield better learner performance. However, this numerically aggregated measure overlooks the fact that longitudinal trajectories of forum participation temporally vary among learners with different motivations in taking MOOCs. To provide timely support for learners to stay engaged, it is important to understand the temporal variation of longitudinal forum participation and how different motivations account for the variance. Using educational data mining techniques, this research identified three clusters with different longitudinal participation trajectories and also indicated that intrinsically motivated learners outperformed others in their longitudinal forum engagement. Also, examining longitudinal forum participation more accurately differentiated learner performance than the numerically aggregated measure. Last, learners persistently engaging in forums were more likely to perform better in MOOCs. 相似文献

Asynchronous online discussion forums are increasingly common in blended learning environments but the relationship to student learning outcomes has not been reported for anatomy teaching. Forums were monitored in two multicampus anatomy courses; an introductory first year course and a second year physiotherapy‐specific course. The forums are structured with a separate site for each course module and moderated weekly by staff. Students are encouraged to post to new threads (initial post) and answer queries in threads started by others (reply post). Analysis of forums was conducted separately for each course and included overall activity (posts and views) for a full semester and a detailed analysis for one week in the middle of semester. Students were classified as zero, moderate, or high contributors to the forums based on the number of posts. Final mark for the course was related to level of forum contribution using nonparametric tests. Forum threads were characterized as task‐focused, administrative, or other. A higher proportion of second year (36%) than first‐year (17%) students posted on the forums and the postings were more likely to be task‐focused and student initiated. Second‐year students that posted frequently to the forum gained a higher final mark for the course than those that did not post or only posted a moderate number of times (P < 0.01). This relationship was not evident for first‐year students who had a much higher proportion of administrative threads. Forums in anatomy courses can be powerful learning tools encouraging deeper learning and improved learning outcomes. Anat Sci Educ 6: 101–106. © 2012 American Association of Anatomists. 相似文献

Asynchronous online discussion forums are common in blended learning models and are popular with students. A previous report has suggested that participation in these forums may assist student learning in a gross anatomy subject but it was unclear as to whether more academically able students post more often or whether participation led to improved learning outcomes. This study used a path model to analyze the contribution of forum participation, previous academic ability, and student campus of enrolment to final marks in a multicampus gross anatomy course for physiotherapy students. The course has a substantial online learning management system (LMS) that incorporates asynchronous forums as a learning tool, particularly to answer learning objectives. Students were encouraged to post new threads and answer queries in threads started by others. The forums were moderated weekly by staff. Discussion forums were the most used feature of the LMS site with 31,920 hits. Forty‐eight percent of the students posted at least once with 186 threads initiated by students and a total of 608 posts. The total number of posts made a significant direct contribution to final mark (P = 0.008) as did previous academic ability (P = 0.002). Although campus did not contribute to final mark, there was a trend for students at the campus where the course coordinator was situated to post more often than those at the other campus (P = 0.073). These results indicate that asynchronous online discussion forums can be an effective tool for improving student learning outcomes as evidenced by final marks in gross anatomy teaching.

网络诗歌犹如现代版文学神话,骤然改变了中国诗歌的版图。当诗人们哀叹文学死亡,诗歌的边缘化、私人化与平庸化时,网络诗歌却呈现出诗歌的世纪复兴。在虚拟世界的互联网上,数以千万计的诗歌网站、诗歌博客等色彩纷呈的诗歌圈子和QQ诗群,已构成网络诗歌的辽阔疆域。网络诗歌的发展,可以分为前后两个阶段：第一阶段是1998年至2004年＂诗歌网站和诗论坛＂阶段,第二阶段是2004年至2008年的＂博客诗＂阶段。网络诗歌在2008年汶川抗震大潮中激情登场,恢复了诗歌的神圣性和非功利性,呈现出精品化、群体化、生长型等诸多特征,但网络诗歌由于缺乏商业获利模式,其创作主流化尚需国家文化资源的扶持。 相似文献

This study presents three case studies of students' participation patterns in an online discussion to address the gap in our current understanding of how individuals experience asynchronous learning environments. Cases were constructed via microanalysis of log-file data, post contents, and the evolving discussion structure. The first student was Thorough, reading all the posts in the forum in sequence, revisiting different posts multiple times, and creating posts outside of the discussion tool. The second student was Self-Monitoring, revisiting his own posts multiple times, checking the discussion frequently for replies, and replying to or editing his posts in response. Finally, the third student was Independent, using the forum as a tool for her own individual reflection. The behaviors found for these cases are aligned with a theoretical taxonomy for participation proposed by Knowlton (2005). The value and limitations of the microanalytic case study approach are discussed, and implications for research and practice are suggested. 相似文献

Social networks enable people with intellectual disabilities (ID) to participate actively in society and to promote their self-determination. However, concerns have been raised regarding the potential limitations of people with ID to deal with untrustworthy information sources on the Internet. In an experiment, we assessed how adult students with ID evaluated recommendations in Internet forums authored by either self-reported experts or by users under pseudonyms who supported their claim either with documentary sources or their personal experience. We compared the performances of students with ID to that of students of similar ages but higher educational levels (chronological age-matched control group) and to younger students with similar verbal mental age (verbal mental age-matched control group). Participants were asked to evaluate to what extent a fictitious user should follow particular recommendations given in a forum and to justify their evaluations by writing a message to the fictitious user. Students with ID, as opposed to the two control groups, recommended the forum advice to a higher extent regardless of authorship and evidence used, and they included in their messages to the fictitious user a higher number of opinions and information sources not present in the forum without linking them to the actual discussion. The pattern of results suggested that students with ID have a limited ability to evaluate recommendations in forums and that they do not necessarily present a delay in the development of these abilities, but rather an atypical development. Finally, we discussed the potential implications for teaching digital literacy to students with ID. 相似文献

This case study provides evidence-based suggestions for the use of Question and Answer discussion forums for improving quality and assessment of online learning. General online discussion forums are accessible at any time to all subscribers, making it possible for some learners to update, concur with or paraphrase discussions posted earlier by their peers or the tutors. Consequently, the usefulness of such forums in individual and constructivist learning is compromised, especially when ‘correct’ responses are posted early on by participants. The Question and Answer (Q & A) version of discussion forums significantly addresses such inadequacies by restricting access to forum subscribers until they have made a post. We focus on Public Health learners’ perceptions of Q & A discussion forums implemented at Hamdan Bin Mohammed Smart University, UAE. Analyses of learners’ perception surveys of 25 participating Master of Public Health learners and 8 Bachelor of Health Administration learners reveal that the Q & A discussion forum platform offers distinct advantages over general discussion forums in synergising individual and co-operative learning in Public Health training. 相似文献

Collaborative mentor support in a learning context using a ubiquitous discussion forum to facilitate knowledge sharing for lifelong learning 总被引：1，自引：0，他引：1

The Internet has recently been identified as a potential enabler of lifelong learning. Web‐based learning systems enable learners easily to access rich resources and actively participate in learning activities without time and distance limits. The main challenge in lifelong learning is providing the opportunity for discussion and collaborative knowledge construction to engage learners in acquiring and applying knowledge in the context of learning, working and collaboration. Moreover, knowledge sharing is a key component in the formation of communities of lifelong learners. Most online collaborative learning communities use Web text‐based discussion forums for knowledge sharing. However, such discussion forums are separated from the context of learning activities. Furthermore, the facilitation of beneficial dialogue through discussion forums, requires the involvement of mentors as facilitators. This study proposes an e‐book interface that enables learners easily to annotate or enter queries in a text in which questions arise, where a query context is transferred to a discussion forum. The subsequent anchors of questions are linked to a discussion forum for actuating sustained participation. A mentor finder recommends a collaborative peer based on learner knowledge level to answer the questions. Learners can also use mobile phones to access this ubiquitous discussion forum using voice/text anytime and anywhere. The experimental results showed a clear increase in the level of discussions, and most learners indicated that they benefited considerably from collaborative mentor support in an e‐book learning context through the provision of a ubiquitous discussion forum. 相似文献
