E-learning中基于Web的概念图协同创作系统研究

A Research of Web-based Collaborative Concept Mapping Authoring System in E-learning

概念图是学生协作知识建构的一种有效支持工具，然而在Web环境下概念图的协同创作系统的研究却并不多见。鉴于此，文章通过对协作学习中概念图的理论研究，分析了概念图协作创建过程中学习者的认知过程，设计了基于概念图的协作知识建构的理论模型，设计了概念图协作创作系统的功能模型和动态模型，介绍了基于Flex和FMS技术的系统实现方案，讨论了系统功能和实现过程。文章的研究成果能丰富协作知识建构的理论研究，推进概念图在网络协作学习实践中的应用。

Concept map is an effective tool that supports knowledge building of learners. However， the researches of collaborative concept mapping authoring tools based web are rarely seen in the fields of educational technology. According to this， this paper reviews the literatures about concept map in both of researches of collaborative learning and knowledge building， and designs a theoretical model of collaborative knowledge building based on concept map， and analyzes the cognitive processes of learners in constructing concept map collaboratively， then designs the functional model and dynamic model of the collaborative concept mapping authoring system，describes the development scheme that explores both of Flex and FMS technologies， finally discusses the functions and development process of this system. This work can enrich the theoretical researches of collaborative knowledge building， and promote the applications in online collaborative learning of concept map.
