摘要
知识表示是实现个性化教学的基础。知识点是教学活动过程中传递教学信息的基本单元,知识点之间的关系可用一个总体树/局部图的组织模型来表示,这与XML文档的树形结构相合。利用XML良好的语义性来描述结构化的学习资源是为了容易地实现远程教育信息的标准化和智能教学导航。
Knowledge expression is the foundation to realize individualized teaching.Knowledge point is the basic unit to transfer teaching information in teaching course,its relations can be expressed with a whole-tree/part-graph organizing model,which corresponds to the tree structure of XML document. The aim to describe structural learning source using better semantic character of XML is to implement the standardization of long-distance education information and intelligent learning navigation easily.
