Information technology brings great impact to higher education teaching. It is of great significance to cultivate high quality engineering talents with both morality and ability, explore the ideological and political teaching mode of courses supported by information technology, and realize the cooperative education of professional courses and ideological and political courses. The concept and practical significance of curriculum-based ideological and political teaching are clarified. After four years of teaching practice of curriculum-based ideological and political teaching, it is concluded that there are problems in the teaching practice of engineering mechanics curriculum-based ideological and political teaching, such as the students’ relatively low sense of participation, the teaching means of ideological and political courses are relatively traditional, and the teaching links of curriculum-based ideological and political teaching are relatively single. In view of the above problems, the ability goal, knowledge goal and education goal of each module of the teaching content of engineering mechanics course are defined. And the use of multimedia and micro-course production is put forward to improve students’ sense of participation, bridge model loading competition and finite element software simulation analysis are used to innovate the form of ideological and political courses, the introduction of learning mobile application and the integration of new media platform are put forward to enrich the ideological and political course implementation means. Finally, taking the course of rational design of beam as an example, the implementation process of ideological and political teaching links of engineering mechanics course supported by information technology is explained in detail through teaching design.
