Recently, the Ministry of education and other 10 departments issued the "work plan for comprehensively promoting the construction of" big ideological and Political Courses ", proposing to fully mobilize the forces and resources of the whole society, build" big classrooms ", build" big platforms ", build" master funds ", solve the current difficulties in the construction of Ideological and political courses, and make ideological and political courses live, practical and strong. The construction of Ideological and political "big classes" is not a large number of large-scale classes, but rather places the classes in a grand era, vivid practice and vivid reality, and solves the problem of "under what era background, with what value orientation, by whom, with what content, what methods, and what goals". Only by comprehensively promoting the construction of "big ideological and Political Courses" and better integrating the "small ideological and political classes" on campus with the "big social classes" outside the school can we give play to the educational advantages of multi class coordination and promote the reform and innovation of the teaching system of Ideological and Political Courses.
