Abstract: In response to the problem of the "four disconnects" in the ideological and political construction, namely the detachment of teachers, curriculum, profession, and students, this paper proposes solutions focusing on enhancing teachers' sense of primary responsibility, integrating scientific history into the curriculum, aligning engineering ethics cases with professional content, and encouraging students to actively engage in clarification to elevate empathy levels. These solutions, which embody the “four closeness” to teachers, curriculum, profession, and students, are exemplified through the exploration of the case of “University Chemistry”, a demonstration course in ideological and political education in Chongqing Municipality.

Key words: Ideological and political education, Chemistry, History of science, Engineering ethics
