Abstract: Preparatory education is a critical bridge for overseas students transitioning from secondary education to higher education in China. Chemistry, as a core scientific discipline, serves as a gateway to degrees in science, technology, and engineering. The challenge in preparatory chemistry teaching lies in overcoming language barriers and addressing the diverse educational backgrounds of students. The goal is to stimulate interest in learning chemistry in Chinese and equip students with the foundational skills required for pursuing chemistry-related majors in Chinese universities. Drawing on recent teaching practices, we have developed an integrated “Teaching-Evaluation” system, incorporating elements of Chinese culture into the curriculum. Additionally, this paper summarizes the practical experience of implementing diversified teaching methods in various learning scenarios, with a detailed discussion on “what to teach” and “how to teach”.

Key words: Preparatory chemistry, Overseas students in China, Teaching system, Chinese culture, Diversified teaching methods
