Research on constructivism's teaching methodology and efficacy in the classroom has been conducted in a wide range of domains, but it has mostly concentrated on two areas - the learning of scientific and engineering majors and the acquisition of English as a second language. There are limited research studies on the influence of constructivism on international Chinese education. In the context of China's pursuit of international cultural and educational cooperation, international Chinese education has gradually entered the international public's vision. Constructivism's research on language teaching mainly focuses on English and general second foreign language learning and rarely focuses on the perspective of Chinese as a second language classroom. In this context, the purpose of this study is to explore how constructivism affects the teaching and learning of Chinese in both China and international Chinese teaching environments, and some suggestions for improvement based on constructivism are put forward for the Chinese international classroom. The constructivism teaching method is expected to be beneficial to Chinese learning, improve students' self-learning awareness and learning motivation, and have a positive impact on Chinese learning outcomes. This study will make a minor contribution to the research of constructivism in Chinese teaching and learning.
