Abstract: This paper takes the experiment of “preparation of manganese carbonate” as an example, and applies the teaching mode of problem-based leaning (“PBL”) in the inorganic chemistry laboratory course. Through the design of a series of problems, students are guided to engage in independent learning, cooperative communication, problem analysis and experimental verification, thereby achieving an organic integration of knowledge transfer and value guidance. The application of “PBL” teaching mode in inorganic chemistry experimental education not only provides valuable exploration and attempt for the reform and innovation of the teaching, but also provides an excellent platform for the integration of course ideology and politics.

Key words: “PBL” teaching mode, Course ideology and politics, Inorganic chemistry experiment, Preparation of manganese carbonate
