In the era of new media, various ideologies, ideas and value orientations collide with each other, which has caused a strong impact on college students' thoughts and values. The traditional ideological and political theory course teaching in colleges and universities has no longer met the current teaching requirements and is facing severe challenges. At the same time, with the continuous development of new media technology, ideological and political theory course teaching in colleges and universities has also ushered in a good opportunity for reform and innovation. Under the background of new media, ideological and political theory course teaching in colleges and universities should keep pace with the times, keep correct and innovative, change ideas, constantly improve media literacy, innovate teaching methods, enrich teaching content, build interactive platforms, and strengthen education supervision, so as to always maintain its advanced nature, enhance its sense of the times and appeal, and give full play to its effectiveness.
