Abstract: Ideological and political theory courses are key courses for moral education and talent cultivation. However, the current situation is that "silence syndrome" exists in both the ideological and political education classroom and teaching effect, leading to problems such as the lack of bilateral communication between the subject and object of ideological and political education, the "one-man show" unidirectional teaching mode, the lack of recognition in the teacher-student relationship, the lack of problem awareness in thinking habits, and the lack of practical significance in teaching effect. Based on the grand ideological and political theory courses, to break the awkwardness of "silence syndrome" in ideological and political theory courses, it is necessary to implement an open teaching model of "one point and four lines", and make full use of situational teaching.
