成功的在线协作学习离不开学习者之间的交互，而富有成效的对话则需要协作过程中的监控和调节。研究分析了CSCL平台学生协作学习中的对话内容和社会网络关系，内容分析发现，协作中对话内容的级别与成员之间协商的量正相关，对话的多元性与产生新问题的量正相关，而信息共享型对话与协商性对话、新问题的讨论并未呈现显著的正相关，讨论上整体缺少多向互动，缺乏协同、共享的监控和调节；网络分析发现，这些现象主要归因于个别成员主导的对话模式，此种对话模式阻碍群体的讨论和协作继续进行。研究从共享监控和调节视角提出增强群体成员的集体认知责任感、提供学生对话层级的评价框架和标准、要求学生在对话内容前添加支架、教师全程监控和随时反馈等策略，以促进协作中高级别、多元性对话的产生，并防止协作中个别成员主导的对话模式的产生。
【英文摘要】：
Online collaborative learning cannot be successful without the interaction between learners, while productive dialogue needs to be monitored and regulated in the process of collaboration. This study analyzes the dialogue content and social network relationship of students' collaborative learning on the CSCL platform. Base on content analysis, it is found that the level of dialogue content in collaboration is positively correlated with the amount of negotiation among members, and the diversity of dialogue is positively correlated with the amount of new questions. However, there is no significant positive correlation between information sharing dialogue and consultative dialogue and the discussion of new issues. The overalldiscussion lacks multi-directional interaction, coordination and sharing monitoring and regulation. Through network analysis, it is found that those phenomena are mainly attributed to the dialogue mode dominated by individual members, which hinders the group's discussion and collaboration. In order to promote the generation of high-level and diversified dialogue in collaboration and prevent the generation of dialogue mode dominated by individual members in collaboration, this study, from the perspective of shared monitoring and regulation, proposes strategies such as enhancing the collective cognitive responsibility of group members, providing evaluation framework and standards at the dialogue level for students, requiring students to add supports before the dialogue, monitoring the whole process by teachers and providing feedback at any time.
