Amid the digital transformation, fragmented learning has gradually become a mainstream learning method due to its flexibility. As a core course for civil engineering majors, “Principles of Concrete Structure Design” has a complex and abstract knowledge system, making it difficult for traditional teaching models to meet students’ personalized learning needs. Focusing on this course, this paper explores the application of a fragmented learning model based on mind maps from multiple dimensions, including its value, principles, and implementation methods. This study aims to provide new ideas and methods for improving the effectiveness of teaching this course and helping students master the knowledge.
