Abstract. Improving the hands-on ability of students is always an important issue of engineering curriculum. This study introduces an experimental teaching system to improve the teaching quality of mechanical design course for foreign students and develop international competitiveness with strong hands-on ability. The system combines the teaching objective of mechanical design course and learning characteristic of foreign students. The heuristic teaching and the interactive teaching methodology are employed. Besides, a stepped teaching and assessment system is also developed. The experimental course includes three stages, which are the fundamental stage, the improving stage, and the innovating stage. In these stages, students are required to design and analyze different mechanical systems with theoretical knowledge, mechanical components, and Fischertechnik Model. Thus, the performance of foreign students can be evaluated from different aspects.
