Abstract: Purpose/Significance In response to the integration issue between the social “big classroom” and the ideological and political “small classroom”, this paper is to clarify the essential connotation and teaching logic of “great ideological and political courses”, and propose practical path for “great ideological and political course”. Design/Methodology Based on the theoretical framework, historical perspective, era background, and life wisdom, this article clarifies that “great ideological and political course” is a teaching concept and method that effectively connects, interacts, and integrates ideological and political courses with social life. Based on the theme logic, relationship logic, supply and demand logic, and mechanism innovation, this paper clarifies that the “big ideological and political course” adheres to the unity of the small ideological and political class and the social class, the coordination of teacher leadership and student subjectivity, the connection of knowledge supply and learning demand, and the combination of new curriculum content and teaching methods. Conclusions/Findings The “greatness” of the “great ideological and political course” lies in the vastness of the educational and teaching battlefield, the breadth of vision, the grandeur of the pattern, and the forefront of the methods. It is necessary to construct a “three comprehensive education” education pattern, establish a “multi in one” teaching system, optimize “rich and colorful” teaching content, innovate “collaborative and efficient” education methods, and create a “harmonious and good” education atmosphere.
