Coordination titration, an analytical method based on coordination reactions, holds broad applications and significant importance in analytical chemistry. This paper addresses key teaching challenges such as the quantitative calculation of side reactions and the practical application of titration methods through a redesigned course structure. The instructional content has been systematically restructured and delivered using graphic teaching method to enhance visualization and explanation. Furthermore, problem-based learning (PBL) was integrated to implement “+Problem” teaching activities. Teaching practice in a “Top-Talent Class” demonstrated that this approach yields positive educational outcomes.
