Teaching Reform and Exploration of Mechanical Drawing Course Based on OBE-CDIO Concept

As a core basic course in mechanical engineering education, “Mechanical Mapping” plays an important role in cultivating students’ engineering practice and innovation abilities. However, the traditional teaching model has problems such as focusing on theory over practice and insufficient student participation, which is difficult to meet the requirements of modern engineering education for comprehensive ability cultivation. In order to improve the quality of course teaching, this paper conducts research on curriculum teaching reform based on the concept of integrating OBE (Achievement-oriented Education) and CDIO (Conception-Design-Implementation-Operation). By reconstructing the teaching objectives that are oriented towards ability, designing modular and project-driven teaching content, introducing information technology such as virtual simulation and three-dimensional modeling, and implementing diverse dynamic evaluation methods, the curriculum teaching system is systematically optimized. Practice shows that the reform has significantly improved students’ engineering graphic expression skills, spatial thinking skills and teamwork skills, and their academic performance and course satisfaction have been significantly improved. The research has verified the effectiveness and applicability of the OBE-CDIO model in mechanical drawing courses, providing reference for similar curriculum reforms.
