弱关系视角下的虚拟学习社区网络交互分析

Analysis of virtual learning community interaction from the perspective of Weak Ties Theory

虚拟学习社区是网络空间中由学习者建立的一个虚拟社会形态,以交互学习、协作学习为主要学习方式,形成以学习为目的的社交网络。本研究基于弱关系理论,运用社会网络分析法对虚拟学习社区的网络结构和消息传播模式进行了分析,探索了网络关系的微观结构和强度如何影响知识互动的过程和结果。数据证明弱关系是影响虚拟学习社区中信息扩散效率的重要因素,且与社区网络中的子群结构有一定关联。

Virtual learning communities are virtual social networks of interactive learning and collaborative learning established by learners. This paper analyzes the network structure and the message transmission mode in virtual learning communities from the perspective of weak ties theory, and explores how the microstructure and the intensity of the network relationship affect the process and results of knowledge interaction. The results show that weak ties are an important factor influencing the efficiency of information diffusion in virtual learning communities, and correlate to a certain extent with the subgroup structure in the communities.
