Abstract: This article uses the course of Maintenance and Fault Diagnosis of New Energy Vehicles as a carrier to construct a "three stage seven step five integration" teaching reform system to explore innovative paths for vocational education teaching. Through the three-level curriculum design of "basic projects–advanced projects–advanced projects" and "labor spirit–model worker spirit–craftsman spirit", the synchronous improvement of professional skills and ideological and political literacy is achieved. Innovatively adopting a seven step teaching process of "classroom morning meeting–task introduction–knowledge explanation–plan formulation–bench simulation– actual vehicle maintenance–summary and evaluation", forming an integrated teaching mode of "theory, reality and virtuality". Practice has shown that the "job course competition certificate education" five integration education mechanism deeply integrates enterprise job standards ("1+X" certificate), skill competition elements, and ideological and political education goals into the curriculum system, reconstructing the teaching content of "typical work tasks fragmented–teaching resource modularization–curriculum project systematization", effectively improving students' job adaptability, competition level, and professional ethics. After the implementation of the reform, the achievement rate of curriculum teaching has increased to 98.7%, the pass rate of student skill certificates reaches 100%, the award rate of skill competitions has increased by 28%, and the satisfaction rate of ideological and political education in the curriculum has reached 99.2%, forming a new model of curriculum reform that can be promoted as "combining morality and technology, integrating knowledge and practice".
