数据挖掘技术在机考系统中的应用

Data mining method with its application to computer test analysis

本机考系统的特点是将数据挖掘技术应用到计算机机考系统中使之智能化,它能够帮助教师分析全班学生在作业、测试中知识点掌握的情况,分析结果除了包括自动改卷子系统能够将每位同学的考试成绩显示出来以外,最重要的是包括直观地显示出每题的考点及其错误率。分析结果可以及时地向教师反馈学生在做题过程中所暴露出来的教学薄弱环节,帮助教师改变教学课时分布,从学生角度发现和抓住教学重点、难点,重新构造学生学习新路径。

The feature of the proposed computer assisted test system is applying data mining technology to computer test analysis and intelligentizing it.It can help teachers analyze how well students understand the knowledge points in assignments and exams.It can also visualize the test points of each questions and error rates.The results obtained by the system can tell teachers which parts of teaching activities should be enhanced and how to allocate the teaching time for each section.Such system will help teachers to emphasize important points,find difficulty in understanding and reconstruct a new way for students to follow.
