This teaching reform takes the course of “automotive parts mapping” as the core, closely integrates computer technology, and brings a qualitative leap in teaching quality and effect with the help of Creo software, an advanced tool. In this innovative exploration, Creo software has not only become our teaching assistant, but also a powerful platform for students to master mapping skills and deepen their understanding. Creo software infuses the classroom with its excellent 2D drawing, 3D modeling, assembly design and simulation capabilities. Students delve into every detail of mapping through an intuitive digital interface. The optimization of classroom organization has broken the shackles of traditional teaching, built a computer-based evaluation system, combined with data analysis technology, we can more accurately grasp the learning situation of students, and provide teachers with scientific evaluation basis and improvement direction. After the implementation of the reform, teaching quality and teaching effect have been significantly improved, students’ learning interest and initiative have been significantly enhanced, and practical ability and innovation ability have also been significantly improved. All these benefit from the combination of teaching reform and computer technology.
