混合式协作学习共同体的最近发展区、活动耦合与协同认知加工

Zone of Proximal Development,Activity Coupling and Collaborative Cognitive Processing of Community of Blended Collaborative Learning

基于十年的混合式协作学习(BCL)理论与实践探讨,揭示了BCL共同体的特征,分析了构建BCL共同体的意义与原则。认为BCL共同体的"最近发展区"是指其独立地完成任务所决定的现有发展水平与在教师指导或其他优秀共同体帮助下完成任务所决定的潜在发展水平之间的"区域"。同时,探讨了BCL活动耦合模型的建立目的与依据、内容与应用,强调各活动要素的整合与演变关系。基于BCL知识建构三循环模型理论及实践,构建了BCL中的个体认知加工与共同体协同认知加工模型,并在案例分析中探讨了其应用。

Based on ten - yearsv theoretical and practical exploration of blended collaborative learning （ BCL） , this paper revealed the characteristics of BCL community and analyzed significance and principle of constructing BCL community. The author believes that the zone of proximal development （ZPD） of BCL community is the ＂area＂ between current level of development decided by completing the task independently and potential level of development decided by completing the task under the guidance of teachers or the help of other outstanding community. At the same time, this paper explored purpose of construction and basis, content and implementation of activity coupling model of BCL, and emphasized the relationship of integration and evolution of elements of each activity. On the basis of the three - cycle model theory of BCL knowledge construction and its practice, this paper constructed the model of individual cogni-tive processing and community collaborative cognitive processing in BCL, and explored its implementation in case analysis.
