Abstract: In response to the problems of lack of top-level design, fragmented and repetitive ideological and political elements in the ideological and political construction of mechanics major courses, a systematic construction of ideological and political education in mechanics major courses has been carried out. By integrating the construction of courses and ideological and political content, highlighting the unique characteristics of each course, and continuously promoting the reform of ideological and political education through the construction of teaching teams, important measures have been taken to enhance the effectiveness of education and provide an exploratory path for the organic combination of mechanical discipline education and ideological and political education.
