摘　　要： 群组内部的交互机制是当前CSCL研究领域的焦点问题。国内外相关研究发现,互动网络结构是发现群组内部交互工作机理的有效方法之一。通过综述国内外学者的相关成果,分析协作学习中互动网络的形成过程,归纳出互动网络结构存在五个典型特征:连通性、密集性、中心性、内聚力和角色空间,介绍了每种结构特征的分析与测量方法,在此基础上提出网络协作学习中互动网络结构的分析模型,最后使用教学实验对分析模型进行验证,并获得了有意义的研究结论。 Internal mechanism of interaction has become the focus in the CSCL research field. The structure of interaction network is one certain composite state which interaction relations among learners roll up as time goes by and the effective methods to find the mechanism of interaction in the WebCL. With review the relative research results home and abroad, the author defined the key concepts about the structure of interaction network, analyzed the forming process of interaction, found that the structure of interaction network has five typical characteristics, including connectedness, denseness, centrality, cohesion and role spatiality, and introduced the analyzing method of the each characteristic. On the basis, the author deduced an analyzing model of interaction network structure, and shows the process and results in the case experiments on online collaborative learning. The results of the study will guild the later research of theory, system development and practice of instruction.
