网络课程中知识点的表示与关联技术研究

Study on expression and connection technology of knowledge point in engineering network course

知识点是网络课程中信息传递的基本单元,研究知识点的表示与关联对提高网络课程的学习导航具有重要的作用.给出了知识点、知识点属性的定义.针对网络课程内容与学习对象的特点,建立了描述原子知识点和知识单元的模型.分析了知识点之间的关联,提出了知识点的超文本组织结构和基于知识点的超文本教学控制的设计方法.通过对网络课程知识的描述、分解与关联,实现了网络课程中基于知识点的学习引导与知识的动态优化重组.

The knowledge point was an essential cell which transfereds information in network course, and was important for improving learning navigation in network course for studying expression and connection of knowledge. The knowledge point and its attributes are defined in this paper. The characteristics of network course contents and students are used to build, the model of describing knowledge point and knowledge cell. The connection among different aspects of knowledge was analyzed, and the hypertext architecture of knowledge point and the method for designing hypertext teaching control based on knowledge point were put forward in the paper, where by describing,decomposing and connecting knowledge in network course, learning navigation based knowledge points and dynamic optimal recombination of knowledge in network course were realized.
