Impact of "Comparative Case Learning" on Medical Students' Analytical Ability in Clinical Case

［Abstract］Objective Pathophysiology has high comprehensiveness and practical characteristics. Developing analytical capacity is a major teaching aim of Pathophysiology. This study was aimed to build up the basic knowledge of pathophysiology and develop a critical approach through "comparative case learning" in medical students. Methods A pair of related cases were chosen in this study. "Comparative case learning" was performed in our lecture. Case analysis was tested before and after "comparative case learning"， and a self-evaluation was accessed after "comparative case learning". The scores of case-analyzing test and self-evaluation assessment were statistically analyzed. Results Using“comparative case learning”in pathophysiology could improve medical students' case-analyzing score，especially in clinical syndrome analyzing examination questions（difficult examination questions）. There was a significant correlation between high score of clinical syndrome analyzing examination and students' self-evaluation. Conclusion　Comparative case learning" could improve the analytical，data searching and comprehensive abilities，thereby enhancing a case-analyzing ability in medical students.
