基于问题解决的在线讨论模式分析与个案研究

Analysis of Problem─Solving─Based Online Discussion Pattern and the Case Research

基于问题解决的在线讨论倍受重视并逐歩普及。在线讨论中教师适时的干预和引导对讨论质量有很大的影响。文章在没有教师参与的情况下，通过观察学习者基于问题解决在线讨论的过程，结合序列分析法和量化内容分析法对在线讨论记录进行编码分析，进一歩了解学习者在讨论中出现的行为模式和知识建构的水平，探讨在线讨论过程中可能出现的局限性，为教师的指导和干预提供有效的策略，以期提高在线讨论的质量和学习者解决问题的能力。

Problem─solving─based on the online discussion is attached much attention and gradually popularized. During the online discussion， the teacher appropriately intervenes and guides， which has a great influence on the discussion， without the teacher’s participation. We observed learners’ online discussion process of the problem settlement， combining the lag─sequential analysis and quantitative content analysis. In order to further learn about the sequential pattern of the learner’s behaviors and knowledge─cinstruction levels. The researcher explores the localization during the online discussion and provides the efficient strategy for the teacher’s guidance and intervention. It’s expected that the efficiency of online discussion will be enhanced and the learner’s ability of solving the problem will be improved.
