Based on the perspective of post-05 college students, this paper firstly analyzes the current situation of ideological and political education teaching in the course of “Fundamentals of Engineering Drawing” and the main problems that exist. Subsequently, it puts forward suggestions for improvement in three aspects: to enhance the sense of identity of post-05 college students in course-based ideological and political education, to improve teachers’ perception of this generation of college students, and to improve the interaction between teachers and students in order to promote the effective communication of course-based ideological and political education. Finally, the article clarifies the teaching objectives of the course-based ideological and political education of “Fundamentals of Engineering Drawing” and designs a corresponding teaching program, which is of certain reference significance to the reform and practice of course-based ideological and political education teaching in higher education.展开更多
