基于XML技术的自测练习子系统在e-Learning中的应用与实现

XML——Based Test Exercise Subsystem Application and Implementation in e-Learning

该文在介绍e-Learning的概念及意义的基础上,引出了一种基于Web的实时交互式计算机网络课程e-Learn-ing系统。全文介绍了构成e-Learning系统的重要模块自测练习子系统的功能特点及实现方案,分析了XML的技术特征,并详细介绍了知识内容结构模型的构建,包括:知识模型的分层表示、知识点结构定义、XML-DTD文件定义以及测试内容结构的定义。最后介绍了系统的使用与安全问题。

This paper,based on the introduction of concept and significance of e -Learning,gives a web -based interactive real time computer network course of e-Learning system,introduces the function and implement ation scheme of self -test and exercise subsystem,which is an important module of e -Learning system.It analyzes technical characteristics of XML and introduces the construction of content structure model in detail,including the layering show of knowledge model,the definition of knowledge point structure,and the definition of XML-DTD file and the definition of test content structure.In the end,this paper introduces how to use the system and the problem of safety.
