摘 要: 研究了智能教学系统功能与结构。分析了知识库模型在智能教学系统中的重要地位;通过对知识库中的教学内容与教学规则两类知识的分析和对超媒体知识表示的研究,构建了一个基于层次结构的超媒体网络模型,并在知识网络图中节点里嵌入教学规则,以实现教学内容的动态组织、呈现和教学过程中的自适应导航。该模型为教学系统的决策与分析提供了智能的辅助手段。 The function and structure of intelligence tutoring system are researched. The important position of knowledge base model in intelligent tutoring system is analyzed. Through analyzing the two knowledge types of teaching contents and rules in knowledge base and studying hypermedia knowledge representation, a hypermedia network model based on hierarchical structure is constructed, and teaching rules are embedded in the nodes of knowledge network graph, so as to realize the dynamic organization and show of teaching content, and adaptive guide in teaching process. This model provides the intelligent auxiliary means for the decision and analysis in teaching system.
关 键 词: 智能教学系统 知识表示模型 自适应学习机制 超媒体
