虚拟学习社区社会网络中的整体结构及块模型分析

The Whole Structure and Block Model Analysis of Social Network in Virtual Learning Community

文章通过社会网络分析,对一个班级的网络社区进行研究.通过块模型分析了解网络的整体结构以及各个子群之间的关系,以探讨虚拟学习社区中群体内部的关系.研究结果表明,虚拟学习社区成员间联系较为密切,整个网络分为4个子群,它们处于不同的网络位置,且每个子群内部交互的差异较大.最后,对教师如何促进虚拟学习社区中成员的交互提出建议.

Social network analysis is used in this paper to analyze a web-based virtual learning community. Based on the block model,the whole structure and the subgroups of network are analyzed,with a view to finding out the relationship among these subgroups in the virtual community. The research results have shown that the whole virtual learning community can be divided into 4 subgroups. The virtual community members are closely related,but there is a remarkable difference between the subgroups in terms of internal interaction. Finally,some suggestions are made for the possible ways to promote the interaction among the members in the virtual learning community.
