A Blended Online-Offline Model for Cultivating High-Order Engineering Ability in "Automotive Parts Design and Modeling"

Aiming to address the issues of single teaching methods, the lack of students' subjectivity, and insufficient personalized guidance in automotive parts design and modeling, this paper constructs a mixed teaching system: “three-dimensional module drive + dual-track integration implementation + whole-process quantitative evaluation.” By dividing three modules: theoretical study, literature reading and practical application, the closed-loop teaching of "preview on the front line of class-deepening off the middle line of class-project expansion after class" is realized by relying on the online platform, and a multi-dimensional evaluation mechanism is established. Practical data show that after the reform, the average score of students' courses has increased by 8.87 points, the passing rate has increased by 19.06%, and their interest in learning and autonomous learning ability have been significantly enhanced. This paper provides an operable implementation path a practical basis for the mixed teaching reform of engineering practical courses.
