在线学习环境中学习行为对知识建构的影响

知识建构水平是学习者在线学习状况的重要标志，是远程教育的研究热点。但知识建构水平的研究多从质性分析的角度出发，鲜有研究从学习者交互行为数据的角度，探究学习行为与知识建构水平的关系。本研究试图发现学习行为与学习者知识建构之间的关系。通过对平台中的学习行为进行提取，完成了统计分析。采用内容分析获得学习者的知识建构水平的表征值，通过相关性分析挖掘学习行为与知识建构水平的关系。研究发现，不同的学习行为分别对不同层次的知识建构产生影响，评价规则促进了观点分享，反思性和社会性学习行为促进意义协商。

Virtual Learning Community is often based on written argumentative discourse of learners， which are aimed to acquire knowledge. The level of knowledge construction is an important aspect of participants’ performance. A great number of researches have discussed how interpersonal communication affects knowledge construction. But the influencing factors of knowledge construction are not limited to collaborative communication. Individual independent learning behaviors may also have great effect on knowledge construction. In the virtual learning community， on one hand， students take part in online discussion and collective activities. on the other hand， they upload materials， use assistive tools and read courseware. In order to improve targeted instruction intervention， we need to study the influence of learning behavior， no mater the interpersonal or individual learning behaviors， on the processes of knowledge construction. Through analyzing online behavior data and textual data， we aim to reveal the relation between learning behavior and knowledge construction and find out which behavior will provoke knowledge construction.
