Building upon foundational experiments in redox titration and spectrophotometry, this study outlines the design and execution of an innovative, comprehensive experiment framework for determining permanganate index (COD_Mn) in drinking water. Central to this approach is a student-focused methodology that enhances practical and inventive skills through comparative analysis of two distinct techniques. This process not only bridges gap between theoretical knowledge and experimental practice, but also integrates teaching with research to underscore the distinctions between conventional and novel methods, verified and innovative experiments, and between simulated and actual samples, showing the high order, innovation and challenge of experimental course. By emphasizing the dual nature and degree of experimental coursework and incorporating ideological and political elements, the experiment fulfills the fundamental mission of moral education. Additionally, the establishment of a procedural evaluation system enables a thorough and systematic assessment of the experimental activities, significantly contributing to the pedagogical process. This innovative experiment offers valuable insights in the reform of experimental teaching within the field of analytical chemistry.
