Abstract：

In the context of increasing emphasis on experimental teaching in the new curriculum standards, this study addresses prevalent issues in current chemistry experiment instruction—such as low student participation, insufficient resources, and excessive teacher direction. Using the “Preparation of Oxygen” experiment as a case study, we conducted student-centered research on junior high school chemistry experiment teaching. Through literature analysis, comparative teaching practice, and questionnaire surveys, we examined the differences between traditional teaching methods and student-centered instructional models. The findings indicate that a project-based learning (PBL) approach centered on student agency significantly enhances students’ exploratory skills, hands-on practical abilities, and scientific literacy.
