Take Zhengzhou University of Light Industry for example, aiming at the problems existing in the traditional electronic training teaching mode, this paper proposes the teaching concept of "project driven+subject competition", and explores the open experimental mode after class to increase students' interest in learning, improves their autonomous learning and comprehensive analysis abilities, and cultivates students' unity and cooperation, hands-on ability, and innovation awareness. Based on our advantageous discipline competition experience, the teaching units of electricians and electronics are closely connected, thereby mobilizing students' enthusiasm to participate in discipline competitions. Teachers' teaching skills, teaching level, and comprehensive ability are improved in the teaching reform.
