Meta-analysis of the Comparison between the Application Effect of PBL Teaching Method and LBL Teaching Method in the Teaching Process of Urology
Objectives To explore the comparison of the application effect of PBL teaching mode and LBL teaching mode in the teaching process of urology,and provide a basis for the selection of teaching methods in the clinical teaching process of urology.Methods The databases of Wanfang,VIP and CNKI were systematically retrieved from January 1st,2010 to May 31st,2022 for comparative articles on PBL teaching method and LBL teaching method in urology teaching.The extracted indicators mainly include grades,classroom atmosphere,learning interest,and the improvement of students'abilities in various aspects,etc.,and the statistical software Review Manager(version 5.3)was used to analyze and evaluate the data.The results of the meta-analysis were presented in a forest plot.A random-effects model was used for comparisons with large heterogeneity,and a fixed-effects model was used for comparisons with small heterogeneity.P＜0.05 was considered statistically significant.Results Twelve studies involving 1221 urology clinical teaching students were included.Meta analysis showed that compared with LBL teaching mode,PBL teaching mode can significantly improve students'satisfaction with teachers(OR 4.94;95%CI 1.77,13.79;P=0.002),and improve learning interest(OR 2.96;95%CI 2.04,4.30;P＜0.00001),improved comprehension(OR 4.07;95%CI 2.16,7.66;P＜0.0001),more active classroom atmosphere(OR 4.54;95%CI 3.11,6.65;P＜0.00001),improved teamwork ability(OR 9.70;95%CI 2.38,39.61;P=0.002),improved clinical analysis ability(OR 3.97;95%CI 2.75,5.72;P＜0.00001),improved learning initiative(OR 9.61;95%CI 1.15,80.57;P=0.04),improved self-learning ability(OR 8.74;95%CI 1.66,45.95;P=0.01),improved literature review ability(OR 14.74;95%CI 1.69,128.52;P=0.01),and expression ability(OR 3.92;95%CI 1.76,8.72;P=0.0008),etc.Conclusions Compared with the CBL teaching method,the PBL teaching method had significant advantages in improving student satisfaction,learning interest,understanding,analysis and expression ability,learning initiative and self-study ability,literature review and self-study ability in the teaching process of urology surgery,which was worth further promotion and application in the teaching process.
