Abstract: As a fundamental course in university-level chemistry, Inorganic Chemistry encompasses numerous discrete knowledge points, which can often make it difficult for students to develop a cohesive understanding of the subject. To foster deeper connections between chapters, this study uses “ammonia synthesis” and its related reactions as a thematic thread, designing a series of interconnected teaching cases. Comprehensive examples are carefully crafted to integrate key concepts such as chemical reaction principles, equilibria in aqueous solutions, and atomic and molecular structures across three levels: gas-phase reactions, solution behavior, and microscopic structures. Mind maps are also employed to aid in connecting these key concepts, enhancing students’ cognitive processing. By blending course content with ideological education, this approach trains students’ thinking skills and fosters knowledge internalization while guiding them towards value-based learning. Teaching practice has shown that this multi-point connection approach improves students’ understanding of the relationships between key concepts, facilitates review and memorization, enhances knowledge transfer, and promotes deep learning.

Key words: Inorganic chemistry, Multi-point connection, Blended teaching, Ammonia synthesis, Mind map
