Abstract: Cognitive diagnosis could diagnose whether students master or not for each attribute, and organize individual teaching according to diagnosed results to improve the quality of teaching. Combining item response theory and similarity measure, a cognitive diagnosis method based on estimated class centers and generalized distance has been proposed to improve diagnostic accuracy. Simulation studies show that in most cases, the accuracy of this method is higher. The improvement of diagnostic accuracy can promote the development of individual teaching and has important practical significance for the improvement of teaching quality.
