Teaching Exploration of Multi-Dimensional Mixed Specialized Courses to Strengthen Practical Ability--Take the Course "Automobile Performance and Test" as an Example

In view of the prominent issues in current engineering course teaching, such as the serious disconnection between theoretical teaching and practical application, and the insufficient cultivation of students' innovative ability, this paper puts forward a multi-dimensional mixed teaching mode that focuses on strengthening practical links. Taking the course "Automobile Performance and Test" as a specific practice carrier, this mode breaks the limitations of traditional teaching by establishing an expert teaching team with in-depth school-enterprise cooperation. It constructs a four-dimensional integrated teaching system covering "online knowledge construction-offline topic deepening-project practice empowerment-enterprise resource linkage", which makes up for the lack of attention to multi-level ability training in traditional mixed teaching. Through two years of teaching practice verification, this mode has significantly improved students' professional quality, practical operation skills and innovative problem-solving ability. It not only provides an effective way for students to connect theoretical knowledge with engineering practice, but also offers a referable teaching paradigm for higher engineering education to adapt to the national strategic demand for compound technical talents, and has important promotional value for similar professional course teaching reforms.
