Abstract: This paper analyzes the necessity of on-line and off-line mixed teaching of Automotive Engineering Materials. The implementation channels of on-line and off-line hybrid in the course teaching reform is expounded from the aspects of course knowledge system, teaching contents, teaching resources, teaching methods, examination methods and continuous improvement, etc., combining with the course characteristics and the guidance and requirements of the first-class course. Through the mixed teaching of leading before class-learning in class-reviewing after class-reflecting and improving, it promotes the organic combination of online and offline teaching, and promotes the application and sharing of high-quality educational resources, it mobilizes the enthusiasm of students to study greatly. Teaching practice shows that the establishment of student-centered online-offline hybrid teaching model, improve the learning efficiency of students, and has achieved good teaching results.
