知识发现在网络教学系统中的应用研究进展

Research Progress of Knowledge Discovery in E─Learning System

网络教学系统中汇集了大量数字化信息，充分利用这些信息进行知识发现以支持教学决策，日渐成为网络教学系统开发的重要思路。本文对近几年的相关研究展开文献调研，揭示了知识发现在网络教学中应用的研究进展，包括国内外研究现状、研究内容、研究热点和趋势等，这将为勾勒网络教学中知识发现应用的整体框架提供前期性的基础研究。

There are a large number of data in a running e─Learning system. Discovery these data to offer gist for instruction decision has gradually become a new idea of e─Learning system development. In this paper， current studies of knowledge discovery in e─Learning are reviewed to reveal the research progress in this field， including the research achievements at home and abroad， research contents， hotspots， trends and so on. This work may lay a foundation for further study about the framework of knowledge discovery in e─learning.
