AIM:To investigate the effect of case-based learning ( CBL) teaching combination with paper review method in the teaching of ophthalmology residents. ·METHODS:The study was conducted from 2015 to 2016. The residents in Department of Ophthalmology, Shanghai Jiao Tong University Affiliated Sixth People's Hospital were included in the research. During the year of 2015, the traditional lecture-based learning ( LBL) method was applied (as a control group). During the year of 2016, the CBL teaching combination with paper review teaching method was applied (as an experimental group). At the end of the course, exams and questionnaires were conducted to evaluate the teaching effect of two different methods. The exams consisted of theoretical and operational assessment. The teaching satisfactions, learning interests, scientific research interests and clinical abilities were included in the questionnaires. The data was analyzed by SPSS 16. 0. ·RESULTS:The results of final exams indicated that the scores of the experimental group (88. 2±6. 5) were higher than the control group ( 75. 6 ± 6. 0 ). The difference showed statistically significant (t=6. 68, P<0. 05). The results of questionnaires indicated that students showed much more satisfied with CBL teaching combination with paper review teaching method ( 91%) than traditional teaching method (50%, x2 =8. 84, P<0. 05). Students in the experimental group improved learning interest ( x2 =6. 29, P<0. 05), increased research interest (x2=4. 54, P<0.05) and approved clinical ability (x2 =4. 25, P<0. 05). The comparison of two groups showed the statistically difference (P<0. 05). ·CONCLUSION: CBL teaching combination with paper review teaching method is beneficial to improve the teaching effect, and it is also beneficial to train residents'clinical skills and research abilities.
