Abstract: Based on years of teaching experience, the teaching mode is gradually improved to form a practical teaching mode that promotes learning and teaching by competition. With the life cycle from product research and development to operation as the carrier and the competition project practice as the driving force, the training of excellent electromechanical engineers is embedded in each teaching practice session. This teaching model fully arouses students’ enthusiasm and initiative, and improves students’ practical ability, innovative thinking and team spirit. The practice shows that the practice teaching reform promotes students to achieve excellent results in innovation and competition, and also urges teachers to create a comprehensive practice session of mechatronics.
