中文摘要：

反思型异步网络学习模式是指学生在面对面的教师讲授、小组协作或在线阅读文本、观看视频、探究解决问题等学习活动后,采用记录笔记和日记、发表评论和留言等方式来内化知识,反思学习过程的一种课余补充式网络学习模式。此种模式中,学生的在线参与可以分为学习型参与和交流型参与。利用行动研究法和内容分析法,借助Blog工具研究者对该模式开展实证研究,制定出学生在线参与度的评价标准,并试图分析参与度与学业成绩的相关性,以此说明提高参与度的重要意义。利用社会网络分析方法,借助Ucinet软件研究者对该模式中交流型参与的网络关系进行分析,探讨社群网络结构和影响交流型参与的因素,并给出提高学生参与度措施的具体策略。

英文摘要：

Reflective asynchronous e-learning model is a kind of supplemental after-class learning model in which students can internalize knowledge and reflect learning activities afterwards by means of note-taking,comments,etc.The learning activities include face-to-face teaching,group work,problem-solving,and so on.The student participation in this model can be divided into two kinds：learning-based participation and communication-based participation.Action research method and content analysis method are undertaken to develop an evaluation criteria of student online participation,and the relation between the student participation and academic performance are analyzed.Furthermore,network structures of communication-based participation are analyzed by using social network analysis,and the factors of community-based participation and network structures are inquired.At last specific strategies are recommended to improve student participation.
