Abstract

Abstract:

In order to cultivate practical and versatile talents in the field of safety engineering, this study explored the problems caused by course content repetition and proposed solutions. The study analyzed the 28-course curriculum of a safety engineering program, identified and quantified the duplication of knowledge points, and applied the APRIORI algorithm to analyze the course association rules which cover all repetitive points of the courses. Then, based on the calculation results, the possible reasons and corresponding effects are given. Meanwhile, the universality of such problems is analyzed by comparing with the contents of other courses, and the basic methods to reduce the repetition of course content are given. The results show that 41 knowledge points had different degrees of repetition, which was mainly caused by unreasonable teaching design and an imperfect course management system. The study also identified 10 strong association rules between course syllabi and knowledge points, covering 11 courses with high support and confidence levels, indicating a strong correlation between course content. This problem was found to be widespread and could be addressed by optimizing course integration, highlighting content characteristics, and adopting various teaching methods.

Key words: APRIORI algorithm, safety engineering, module, course content, repeat content
