项目摘要

The purposes of this research are to (a) generate metadata of Learning Entity to support CSCL in e-Learning environment, and embodiment of the knowledge sharing by the reference model and to (b) extract the educational knowledge about a design and instruction of collaborative study environment using the data base that consists of collaborative learning cases with metadata. We got the following results.(1) We surveyed about bases of Computer Supported Collaborative Learning.(2)From the analysis of the survey, we found the importance in a design and instruction of collaborative learning. And we proposed group composition and the description system of a workflow. Based on this proposal, we developed the editor for a teacher to describe collaborative learning graphically.(3)We arranged about the function of collaborative learning based on the argument on it. We proposed and verified the collaborative learning description metadata form in the text chat CSCL based on this result.(4)We proposed the description framework for positioning collaborative learning in e-Learning. We proposed the expression form by the combination of the three attributes that are technology, environment, pedagogy.(5)We developed the agent system that can perform information gathering by text mining technology on the electronic bulletin board on collaborative Learning space.

本研究的目的是（a）生成学习实体的元数据以支持电子学习环境中的 CSCL，并通过参考模型体现知识共享；以及（b）提取有关协作设计和教学的教育知识使用由带有元数据的协作学习案例组成的数据库的学习环境。我们得到了以下结果：(1)我们对计算机支持的协作学习的基础进行了调查。(2)从调查的分析中，我们发现了协作学习的设计和指导的重要性。并提出了工作流的组构成和描述系统。在此基础上，我们开发了供教师使用的编辑器，以图形方式描述协作学习。(3)在论证协作学习的基础上，对协作学习的功能进行了整理。在此基础上提出并验证了文本聊天CSCL中的协作学习描述元数据形式。(4)提出了在e-Learning中定位协作学习的描述框架。我们提出了技术、环境、教育学三个属性相结合的表达形式。(5)开发了能够利用文本挖掘技术在协作学习空间的电子公告板上进行信息收集的代理系统。
