Book excerpt: Studies on Learning and Teaching Chinese as a Second Language represents the current advances in the field. It showcases theoretically motivated empirical studies and diverse methods used for a better understanding of how Chinese language is acquired as a second or foreign language. This contributes to L2 acquisition research in general and L2 Chinese specifically. Furthermore, this research is useful for teachers seeking to understand their students’ learning processes and adjust their pedagogical approach for more effective instruction. The book bridges the gap between research and instruction by providing pedagogical implications rooted in empirical findings.
