基于粗糙集理论的影响高校学生成绩因素研究
Research on Factors Affecting College Achievement Based on Rough Set
摘要
Abstract
Achievement is an important indicator of teaching quality and student learning. Because of many factors that affect student’ s a-chievement,teachers and students cannot clearly recognize the key factors affecting the results. Therefore,on the one hand,teachers cannot make an improvement to teaching methods to improve the quality of teaching. On the other hand,students are unable to make targeted im-provements to the learning methods to improve study performance. To help college students and teachers for analysis of key factors influ-encing academic performance accurately,a questionnaire about factors affecting college student achievement is designed. Those data are collected from the school’ s freshman to senior,then using heuristic attribute reduction algorithm based on information entropy in rough set theory to identify the key factors affecting the performance of college students,and next applying improved property values reduction algorithm based on resolution matrix in rough set theory to mine key factors affecting student achievement and college students dependen-cies between the results derived the rule set. Finally through the experiment,the validity of the rule set is verified. Research can help uni-versity teachers and students to understand the key factors that affect performance, thereby improving the way teachers teaching and students learning.关键词
