Abstract: The teaching of the Fundamentals of Mechanical Design course faces prominent problems such as insufficient class hours, scattered knowledge points, single teaching mode, and low learning initiative of students. Taking moral education as the core educational goal and relying on information-based teaching platforms, this paper constructs an online-offline blended teaching mode characterized by "one point, two lines and three faces". By optimizing curriculum resources, expanding teacher-student interaction channels, improving the diversified process evaluation system, and further integrating discipline competitions and curriculum ideology and politics into teaching, the reform effectively stimulates students' learning motivation and improves the overall teaching quality of the course.
