Engineering mechanics course is an important and basic course of engineering specialty， and the content of the course is theoretical. In view of the current teaching situation including the lack of students'' learning ability and innovative training， the ideological and political education of the course should be effectively introduced in the teaching， and the teaching objectives of the course can be realized in the aspects of theory， method and application.

Through their application and the continuous improvement in teaching， students'' performance and satisfaction with the course have been significantly improved.
