Objective:To investigate the application effect of flipped classroom combined with micro-lectures in the teaching of pediatric infectious diseases.Methods:A total of 199 five-year students in the class of 2019 from Department of Pediatrics of Chongqing Medical University were divided into 14 groups. Each group selected a micro-lecture theme targeting the key and difficult points of the course and produced an original micro-lecture video through flipped classroom, which was then uploaded to Chaoxing platform for evaluation by teachers and students. At the end of the course, a questionnaire survey was performed to investigate the teaching effect, and final examination score and department examination score during internship were compared between the students in the class of 2019 and those in the class of 2018. SPSS 22.0 was used to perform the t-test, the Wilcoxon rank-sum test, the chi-square test, and the Fisher's exact test. Results:A total of 14 flipped micro-lecture works were completed by the students. The questionnaire survey showed that 98.47% (193/196) of the students thought that this model was helpful to master the key and difficult points; 93.88% (184/196) of the students thought that the flipped micro-lecture works had better originality and quality than reading reports and literature reviews in the past; 94.90% (186/196) of the students were more willing to accept the mode of flipped classroom combined with micro-lectures. Compared with the students in the class of 2018, the students in the class of 2019 had significantly higher final examination score (79.32±7.53 vs. 76.06±12.01, P<0.001), theoretical score of department examination (88.68±4.87 vs. 87.15±4.09, P<0.001), and operation score of department examination (84.93±7.56 vs. 82.08±9.10, P<0.001). Conclusion:Flipped classroom combined with micro-lectures can effectively solve the key and difficult points in the teaching of pediatric infectious diseases, and it can also stimulate the interest in independent learning and help to improve learning performance among students. Therefore, it holds promise for clinical application.

Objective:To explore the effects of participatory interactive teaching in the clinical internship course of pediatric infectious diseases.Methods:217 undergraduate students of grade 2018 majoring in pediatrics were selected as the experimental group, and 208 undergraduate students of grade 2017 majoring in pediatrics were selected as the control group. The experimental group used the teaching method of BOPPPS combined with case-based learning and team-based learning, while the control group adopted the traditional teaching method. Evaluate the learning effectiveness by comparing the formative evaluation and theoretical exam scores of the two groups , and a questionnaire survey was conducted for the students in the experimental group to investigate teaching feedback. SPSS 19.0 was used to perform the t test for data analysis. Results:The experimental group had significantly better scores than the control group in final theoretical examination [(75.04±9.12) vs. (71.03±9.51), P<0.05] and formative evaluation [(81.03±6.13) vs. (70.02±10.32), P<0.05]. According to the results of the questionnaire survey on teaching satisfaction, the students were satisfied with the interactive participatory teaching method in the four aspects of improving learning interest, improving learning ability, classroom satisfaction level, and course acceptance level. Conclusions:The pragmatic teaching reform in the internship of pediatric infectious diseases is highly accepted by students and beneficial to improving students' clinical thinking ability and comprehensive quality, which is worth further application and promotion.
