摘要
对学院教务管理系统的学生成绩库进行数据挖掘、数据预处理,生成学生成绩训练集,采用改进的ID3算法递归创建学生综合技能评估决策树.决策者通过该模型,分析专业核心课程间的相互支撑关系,易于决策者对学生综合技能分析评估.对提高教学整体质量,科学地构建和整合专业核心课程体系,有一定的理论价值和实践意义.
An educational administration management system was proposed through data mining in the student score database,data preprocessing and student training set.A comprehensive skills assessment decision tree was created using the improved ID3 algorithm.Decision makers may use this model to analyze the mutual support between the relationship of professional core courses,and to analyze and evaluate the student’s comprehensive skills.It is useful to improve the overall quality of teaching,scientific construction and integration of professional core curriculum system.
