基于问题解决的在线讨论模式分析与个案研究

基于问题解决的在线讨论倍受重视并逐步普及。在线讨论中教师适时的干预和引导对讨论质量有很大的影响。文章在没有教师参与的情况下,通过观察学习者基于问题解决在线讨论的过程,结合序列分析法和量化内容分析法对在线讨论记录进行编码分析,进一步了解学习者在讨论中出现的行为模式和知识建构的水平,探讨在线讨论过程中可能出现的局限性,为教师的指导和干预提供有效的策略,以期提高在线讨论的质量和学习者解决问题的能力。     

混合式教学中网上学习动力系统的创建与实践研究——以“网上支付与电子银行”网络课程为例

当前,很多学校都开展了网络课程建设,以期通过传统教学和网络教学的结合,提升教学质量,培养学生的自主学习能力。然而,研究结果显示,很多学生在进行网络学习时积极性并不高,无法长时间坚持在线学习。为解决这一问题,提出应建立学生在线学习动力系统,并结合网络课程的实施进行了研究。研究结果表明,创建学习动力系统是提高教学质量,培养学生自主学习的有效方式。     

《网络课程评价规范》与图书馆用户网络教育的标准化

网络教育技术标准化是保证学习资源共享和各教学系统互联互通的根本措施.文章阐述了图书馆信息用户网上教育标准化建设的意义,介绍了我国的<网络课程评价规范>,提出以此为参照进行图书馆信息用户网络教育工作标准化的几点建议.     

课堂教学与实践教学相结合的模式——成教业余类“法律基础”课堂教学的探索

《法律基础》承担着培养当代大学生法律意识,提高公民法律、素养的重任。而传统的＂黑板粉笔加法条＂进行法理讲解的模式显然难以满足当代大学生尤其成教业余类学生多元化思维方式的需要。针对成教业余类学生多元化的特点,我们在课堂教学中增加讨论性因素,建立师生互动机制;把学生带出教室,走进法院和律所去亲身感受;把律师请进教室咨询,配合课堂教学。从而形成一种课堂教学和实践环节相结合的教学模式。     

让大学讨论课在“无原则的批判”中展开——以武汉大学彭富春的讨论课为个案分析

本文以武汉大学彭富春的讨论课为个案,分析了"无原则的批判"式讨论课所具有的意义。这在于,"无原则的批判"式的讨论课是学习者参与其中的思想游戏,学生全身心投入其中从而成为积极主动的学习者。这种"无原则的批判"式的讨论课是在语言的批判、思想的批判和现实的批判中展开的。     

Integrating e-learning into the Direct-instruction Model to enhance the effectiveness of critical-thinking instruction

The Direct-instruction Model favors the use of teacher explanations and modeling combined with student practice and feedback to teach thinking skills. Using this paradigm, this study incorporates e-learning during an 18-week experimental instruction period that includes 48 preservice teachers. The instructional design in this study emphasizes scaffolding, observational learning, mastery of critical-thinking skills, guided practices, cooperative learning, providing feedback, self-reflection, online discussions, and active participation in an online learning community. This study employs 2 critical-thinking tests, 2 inventories, and 1 open-ended reflection questionnaire; and students’ scores on the pretest and posttest are compared via the Repeated Measure Analysis of Variance. The primary findings are as follows: (a) all participants preferred the instructional design in this study; (b) the experimental instruction effectively improved the preservice teachers’ critical-thinking ability as well as their professional knowledge and personal teaching efficacy concerning critical-thinking instruction; (c) the mechanisms contributing to the effectiveness of the experimental instruction mainly included discussing and sharing, observational learning, self-reflection, guided practice, and the learning community.     

Prospective elementary teachers’ motivation to participate in whole-class discussions during mathematics content courses for teachers

Prospective elementary teachers’ (N = 148) motivation to participate in whole-class discussions during mathematics content courses for teachers, as expressed in their own words on an open-ended questionnaire, were studied. Results indicated that prospective teachers were motivated by positive utility values for participating (to achieve a short-term goal of learning mathematics or a long-term goal of becoming a teacher), to demonstrate competence (to achieve performance-approach goals), or to help others (to achieve social goals). Negative utility values for participating were expressed by those who preferred to learn through actively listening. Five motivational profiles, as composed of interactions among motivational values, beliefs, goals and self-reported participation practices, were prevalent in this sample. Self-reported variations among participants’ utility values and participation practices suggested that prospective teachers engaged differentially in opportunities to learn to communicate mathematically. Results provide pedagogical learner knowledge for mathematics teacher educators.

The role of lead users in knowledge sharing

This paper introduces a model of knowledge sharing in an online community of practice that suggests that knowledge contributions will be made by those who possess the relevant knowledge. For them, matching a ready-made solution to a problem is low cost. We hypothesize that lead users – due to their characteristics – are likely to possess more relevant solution knowledge and thus be centrally involved in contributing knowledge. Our results support the hypothesis by showing that lead user characteristics relate positively to making contributions to the community. In addition, we find that search and integration of knowledge from different external sources of relevance to the community positively moderates knowledge contributions by lead users.
