The return of ideological and political education to the life world is a necessary process for breaking through the boundaries of scientific world and building an institutional one. During the process of ideological and political education, real-life world is the original state of ideological and political education, while the scientific world is the realistic state of ideological and political education, and the institutional world is the future of ideo? logical and political education. At present, the ideological and political education in the scientific world occupies a major position and erodes the development space of the life world. There are some problems, such as ignoring the subjectivity of teaching objects, neglecting the emotion of teaching content, relying on the technicality of teaching carriers, as well as pursuing the digitization of teaching evaluation. In the future, we need to give play to the subjectivity of teaching objects, add the emotion of teaching content, integrate the humanity of teaching process, enrich the process of teaching evaluation, and complete the return of ideological and political education to the life world.
