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）产生学习实体的元数据，以支援数位学习环境中的CSCL，并借由参考模型来体现知识分享;（B）利用包含元数据的合作学习案例资料库，撷取合作学习环境设计与教学的教育知识。我们得到了以下结果。(1)对计算机支持的协作学习的基础进行了调查。（2）通过对调查结果的分析，我们发现了合作学习在设计和教学中的重要性。提出了工作流的组构成和描述体系。基于此建议，我们开发了一个编辑器，教师描述图形化的协作学习。(3)We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格式。(4)We提出了在e-Learning中定位协作学习的描述框架。提出了技术、环境、教育三个属性相结合的表现形式。(5)We在协作学习空间的电子公告板上，开发了一个能够利用文本挖掘技术进行信息收集的Agent系统。
