Abstract: This study implements teaching reforms for the “Chemical Composition Analysis of Materials” course in alignment with the talent cultivation objectives of first-class discipline construction. We developed an integrated pedagogical framework combining online-offline learning with theoretical-practical instruction, incorporating sophisticated instrumentation into experimental teaching. The established “classroom learning - online self-study-group design - experimental implementation” teaching system is supported by a multidimensional evaluation approach. This reform emphasizes student-centered learning while integrating ideological and political elements, effectively enhancing students' professional competencies, scientific thinking, and innovation capabilities through design-oriented experiments.
