For the practical teaching of mechanical design courses,the integration of course-based ideological education,improving teaching efficiency,and enhancing learning effectiveness are key issues.By comprehensively utilizing interactive tools such as the split classroom and online spreadsheet design,this teaching approach focuses on engineering ethics and safety reliability issues to introduce teaching.Students are guided to conduct retrieval learning and design training centered around strength and durability evaluation design,cultivating their engineering ethics awareness and problem-solving abilities.The integration of teacher guidance and student training,as well as skill cultivation and ideological shaping,summarize and reflect on the design process to obtain feedback for classroom teaching.This approach provides guidance for students'future learning and teachers'teaching improvements.
