网络协作学习中的社会网络分析个案研究

Social Network Analysis in CSCL：A Case Study

协作学习可以归结为认知和参与两种形式的学习隐喻的对话，而现有研究很多都集中在学习者的认知特征的分析上，对参与特征的分析较少。因此，本文利用社会网络分析（Social Network Analysis，以下简称SNA）方法，从网络交互的密度、凝聚子群、核心边缘、中间中心度等角度对一门网络课程中学习者之间的社会交往特征进行了实证分析。文章最后对研究结果进行了分析并提出了后续的研究计划。

Collaboration is a form of interaction or a process of participation and can be traced back to the conversation of two metaphors of learning， acquisition and participation， but studies on collaboration emphasize more on the cognitive characteristics than on its situative characteristics. In the paper， the authors identify a set of SNA indicators， such as network density， point centrality， betweennes centrality， network centralization， cohesive subgroups， coreperiphery model and perform a case research to study the social aspects of education master participating on one online course. In the end， the authors discuss the results and propose further research program.
