Application of Engineering Case Teaching Method in Mechanical Design Course Design and Teaching Reform Effect

Based on the actual situation of mechanical design course teaching, this paper discusses the application of engineering case teaching method in course design and its teaching reform effect. By introducing actual enterprise project cases, optimizing the organization and implementation of the teaching process, and integrating the elements of ideological and political education in the course, the students' learning interest, engineering practice ability and innovative thinking ability have been significantly improved. The data show that the students' classroom participation rate has increased from 65% to 85%, the satisfaction with the course has increased from 78% to 92%, and the number of winners in various vocational skills competitions has increased by more than 50%. At the same time, the teachers' teaching efficiency and teaching content optimization ability have also been significantly improved. Although there are still some problems in case resources, teaching evaluation system and student participation, the teaching effect can be further optimized by establishing a case library, improving the evaluation mechanism and introducing incentive measures. In the future, the school will continue to improve the case teaching method, explore more innovative teaching models, and provide support for the cultivation of high-quality application-oriented engineering and technical talents.
