Abstract: “Great ideological and political course” is the key course of the new education concept to carry out the fundamental task of fostering virtue through education in the new era. With the integrated development of all-media technology and ideological and political education, the course highlights the new features of the era of “whole process, holography, all-involvement and full effect” in terms of educational content, carrier, subject and environment. This poses a realistic challenge to the education and teaching of traditional ideological and political theory courses, but clarifies the direction for the development and optimization of the current ideological and political theory courses. To make good use of “great ideological and political course” under the all-media context, we should understand the background of deep integration of the media, and define the “whole process, holography, all-involvement and full effect” characteristics of the construction of “great ideological and political course”. We also need to promote the deep integration of all-media technology and the education and teaching of ideological and political theory courses by building value consensus, accelerating media convergence, improving media literacy and expanding communication pattern so that the “great ideological and political course” can be everywhere and at every time, and can give full play to the key role of ideological and political theory courses in fostering virtue through education, forging inner strength and inspiring people.
