Abstract: This paper focuses on the reform of the teaching methodology for the course fundamental principles of marxism, aiming to address issues such as a fragmented content system, singular teaching methods, and insufficient teaching expertise. In accordance with the course's nature and instructional requirements, the article constructs a comprehensive reform framework from three dimensions: content, methodology, and support mechanisms. In terms of content, a modular teaching system is restructured by integrating fine traditional Chinese culture, the latest achievements in the Sinicization of Marxism, and practical case studies. Methodologically, a three-dimensional teaching model of“theory-case-practice”is innovated to strengthen theoretical explanation, case analysis, and practical exploration. Regarding support mechanisms, a trinity system of“teaching staff-evaluation-resources”is established, safeguarding the reform through faculty training, diversified evaluation approaches, and resource development.

Key words: Basic principles of marxism, “The second combination”, Teaching reform, Teaching mode, Guarantee mechanism, Moral education and talent cultivation
