【摘要】 目前,基于Web的智能教学系院是计算机应用于教育领域的研究方向之一。本文从知识点及其关系出发构建一个知识网络模型,并基于该模型介绍如何进行领域知识表示及考核试题设置,然后设计了试题难度系数的动态更新方法,还提出一种简捷的知识诊断方法,准确地将学生学习缺陷定位到具体的知识点,得出学习路径方面的建议,从而增强了教学的针对性。更多还原

【Abstract】 At present,intelligent tutoring system based on Web was extensively researched.In this paper,a model of knowl- edge network based on knowledge points and their relationship is built,and the methods of applying knowledge network to pre- sent domain knowledge and design exercises are also introduced.And then,a dynamical update method which can solve test- question difficulty coefficient is designed.At last,the paper presents a concise method of knowledge diagnosis,which can pre- cisely determine the study shortcomings of learners,and provide methods for learners to improve individualized education.更多还原
