Abstract: Through literature analysis, this paper sorted out the existing research results from the aspects of the generation background, connotation and significance, content requirements, realistic difficulties and practical paths of the integrated construction of ideological and political courses in universities, middle schools and primary schools, in order to provide reference for further deepening the theoretical and practical research on the integrated construction of ideological and political courses in universities, middle schools and primary schools. Existing research is of great significance to promoting the connotation-based development of ideological and political courses, implementing the fundamental task of strengthening moral education and cultivating people, and implementing the education policy of the Party and the country. At present, most of the research is concentrated on the macro level, with shortcomings such as shallow scientific research, less micro-research on integrated practice, and insufficient research on holistic and systematic thinking. In the future, it is necessary to further explore in the aspects of deepening basic theories, basing on teaching practice, expanding research dimensions, strengthening community construction, etc.
