开放自适应学习平台中的内容由学生交互产生，交互行为与模式的不同会影响知识建构的效果。针对当前研究对开放式平台研究的不足，文章研究以CSCL领域具有代表性的知识论坛为例，基于内容分析和社会网络分析方法对学生发表在平台上的810条有效观点及其交互网络的动态关系进行探讨。结果发现，观点的异步交互行为整体呈现出“马太效应”和“黏性效应”，其纵向发展有“偶尔爆发后持久沉默”“固定例会”“引入随机的细水长流”三种模式。观点整体交互的不均衡性和不同模式“关系力量”的驱动作用对基于开放自适应学习平台的知识建构教学具有参考价值。
【英文摘要】：
The content in an open adaptive learning platform is generated by student interaction, and the different interaction behaviors and patterns affect the effect of knowledge building. In view of the shortcomings of current research on open platforms, this study takes a representative knowledge forum platform in the field of CSCL as an example, and discusses the 810 valid ideas published by students on the platform and the dynamic relationship of their interactive networks based on content analysis and social network analysis methods. The results show that the overall asynchronous interaction behavior of ideas presents a "Matthew effect" and a " viscosity stickiness effect", and its vertical development includes three patterns of "occasional outbursts followed by persistent silence," "regular meetings," and "introduction of a random trickle". The unevenness of the overall interaction of ideas and the driving role of the "relational power" of different patterns have reference value for knowledge building teaching based on open adaptive learning platforms.
