ICAI系统及其开发工具中的知识描述结构

KNOWLEDGE DESCRIPTION STRUCTURE IN ICAI SYSTEMS AND THEIR DEVELOPING TOOLS

首先剖析了当今计算机辅助教学（ＣＡＩ）和智能计算机辅助教学（ＩＣＡＩ）系统中的知识描述结构及其局限性．尔后对ＩＣＡＩ的知识构成进行新的分类．在此基础上，提出一个能够覆盖ＩＣＡＩ系统的多种类型、支持多种教学模式以及包含ＩＣＡＩ各种知识构成的知识描述模型．

This paper first analyses all kinds of knowledge description structures andtheir limitations in the existing Computer Assisted Instruction(CAI) andIntelligent Computer Assisted Instruction(ICAI) systems.Then it makes a newclassification of the knowledge components in ICAI systems. The article, on thebasis of the above-mentioned,gives a general knowledge description structuremodel which may cover various types of ICAI systems,support every teachingpettern and include all kinds of knowledge components in ICAI.
