RESUMEN
Objective:To investigate the application effect of problem-based learning (PBL) in the teaching of professional postgraduate students in hepatobiliary surgery.Methods:A total of 60 professional postgraduate students in the same grade who were accepted by Department of Hepatobiliary Surgery, The First Affiliated Hospital of Chongqing Medical University, were selected as research subjects. The students were randomly divided into PBL teaching group and lecture-based learning (LBL) teaching group, and the training effect was compared between the two groups. SPSS 25.0 software was used for t test and chi-square test. Results:Compared with the LBL group, the PBL group had significantly higher scores of written examination [(90.3±4.5) vs. (85.2±7.1), P<0.05] and skill examination [(92.3±4.9) vs. (86.3±7.9), P<0.05] and significantly better comprehensive abilities such as scientific research ability, clinical ability, organizing ability, literature review, collaboration and cooperation, and language expression [(85.0±7.5) vs. (73.0±9.1), P<0.05], as well as a significantly higher overall evaluation score [(90.2±3.2) vs. (83.3±3.9), P<0.05]. The PBL group also had a higher degree of satisfaction than the LBL group (83.3% vs. 56.7%). Conclusion:Application of PBL in the teaching of professional postgraduate students can improve the quality of teaching.
