Abstract: The contradiction between the ideological and cultural needs of students' growth and development and the "insufficient supply" of ideological and political theory teaching in colleges and universities is the main contradiction that restricts the effectiveness of ideological and political theory teaching in colleges and universities. The effective supply of ideological and political theory teaching in colleges and universities is conducive to enhance the sense of achievement of college students, improve the effectiveness of ideological and political theory teaching, and promote the connotative development of ideological and political theory courses in colleges and universities. In order to improve the classroom teaching effect of ideological and political theory courses in colleges and universities in the new era, we should pay attention to the needs of students, adhere to the principles of demand identification and precise teaching, adhere to the principles of problem orientation, new due to situation, and adhere to the principles of technological empowerment and discourse innovation. From emotional resonance to value consensus, implement temperature teaching of ideological and political courses, from disjointed aphasia to meaning sharing, implement narrative teaching of ideological and political courses, from one-way transmission to three-dimensional interaction, implement dialogue teaching of ideological and political courses, promote the reform and development of ideological and political theory teaching, and improve the ideological and political education system.
