Objective　To evaluate the application of flipped classroom based on rain classroom in standardized residency training of orthopedics. Methods　Sixty-two orthopedics residents were randomly divided into flipped classroom teaching group and traditional teaching group

with 31 residents in each group. The flipped classroom teaching group the flipped classroom teaching mode based on rain classroom

including three aspects: learning in advance before rain classroom

personalized discussing cases in class and teaching after class. The theoretical knowledge

clinical skills and evaluation of teaching activities were compared between the two groups. SPSS 19.0 was used for rank sum test and chi-square test. Results　All the residents completed the evaluation of theoretical knowledge

clinical skills and effect. The results showed that the scores of theoretical knowledge and clinical skills in the flipped classroom teaching group were (88.7±10.3) points and (26.8±2.2) points

which were significantly higher than those of the traditional teaching group (79.2±18.6) points and (20.4±2.9) points

with statistical significance (P<0.05). The evaluation of teaching activities

including participation

satisfaction

enthusiasm and learning effect

was significantly better than that of the traditional teaching group (P<0.05). Conclusion　In the orthopedics standardized residency training and teaching activities

the application of flipped classroom teaching mode based on rain classroom is conducive to improving students' learning performance

cultivate their autonomous learning ability

and improve their learning satisfaction and enthusiasm.
