ABSTRACT

Objective:To study the application of establishing WeChat group combined with PBL teaching mode in the practice of pediatric orthopaedics.Methods:The study was conducted among 36 postgraduates of "5+3" pediatrics and 22 postgraduates of orthopedic surgery of Batch 2012 who had practice in Department of Orthopaedics, Children's Hospital of Chongqing Medical University from September 2018 to August 2019, and they were randomized into control group and experimental group, with 29 students in each group. The control group was taught by traditional PBL mode, while the experimental group was taught by WeChat group combined with PBL mode. At the time of leaving the department, the two groups were assessed by theoretical knowledge, practical operation and questionnaire satisfaction, thus evaluating the teaching effects. The SPSS 23.0 was used to conduct t test and chi-square test. Results:The average scores of theoretical knowledge test (91.28±2.89) and practical operation test (87.44±2.94) in the experimental group were significantly higher than those in the control group (87.39±3.53) and (79.06±3.84), with statistically significant differences ( P<0.05). In the survey of teaching satisfaction, the experimental group[96.55%(27/29)] was significantly higher than the control group[61.90%(21/29)], with statistically significant differences ( P<0.05). Conclusion:The establishment of WeChat group and the combination of PBL teaching model can significantly improve the teaching effect and students' satisfaction in the practice of pediatric orthopaedics, which is worthy of further promotion and application.
