摘要

摘要: 高校在长期的教学活动中积累了大量的课程数据，如何利用数据资源分析课程教学状况，为提高课程教学质量提供决策支持，具有重要的研究价值。本文设计实现了一个基于关联规则与聚类分析的课程评价体系，对课程评价系统进行了功能需求分析，并对课程评价数据进行预处理。采用FP-growth算法对学生课程成绩数据进行关联规则分析，采用K-means++算法进行聚类分析，提高了课程数据分析的精度，实现了课程评价的自动化，提高了效率和评价的客观性。

Abstract: The essential factor to consistently improve the teaching quality of college education relies on the quality of curriculum, which is the basis to realize the reform idea of all higher education. Colleges and universities have accumulated a large amount of curriculum data in long-term teaching activities. How to use data to evaluate the course and provide decision support for improving the quality of course teaching has become an important research field. This paper designs a curriculum evaluation system based on association rules and cluster analysis, then analyzes the functional requirements of the curriculum evaluation and preprocesses the course evaluation data. The FP-growth algorithm is used to analyze the association rules of the score of student course and K-means++ algorithm is used for cluster analysis, which improves the analysis accuracy of course data, realizes the automation of course evaluation, and improves the efficiency and objectivity of evaluation.
