基于DM的网络教学资源的反馈跟踪系统

网络教学资源的反馈跟踪系统是促进教学质量不断提高的重要手段，从以学生为主体的理念出发。研究设计了网络教学资源的反馈跟踪系统。该系统采用DM（Data Mining，数据挖掘）技术中的粗糙集和关联规则对学生在线学习等行为特征数据进行数据收集、数据预处理、构造决策表、基于粗糙集的关联规则的提取，最终得出跟踪反馈的结果，对于推进教学现代化，提高教材质量有重要的意义。

Feedback Tracking System of Network-Aided Teaching Resources Based on DM

The feedback tracking system of network-aided teaching resources is an important method to promote the quality of teaching, this article design the system fi＇om the student perspective. In this paper, we use the rough sets and association rules in the DM technique to data collection about students＇ online learning behavior, data preprocessing, construction decision-making table, association rules extraction based on rough set, finally, we get the results. The system has an important significance to promote the modernization of teaching and teaching quality.
