智能教学中的知识表示与知识诊断研究

Research on Knowledge Representation and Knowledge Diagnosis in ITS

为了有效评估学生学习效果,提高计算机辅助教学系统的智能性,本文通过分析学科知识测试结果,提出了一种简捷的知识诊断方法。同时结合系统构建需要,引入了一种新的知识表达工具-概念网络,并就如何利用概念网络表示学科知识及设置习题进行了详细介绍。

To evaluate a student＇s learning effect availably and improve the intelligence of a CAI （Computer Assisted Instruction） system, a concise method of knowledge diagnosis is presented by analyzing the test results of knowledge leaning. For the purpose of building the system, a new knowledge representation tool -conceptual network is introduced, and the methods of applying conceptual network to represent domain knowledge and to design exercises are also illuminated finely in this paper.
