Subclaims¶

q3 i? In the diagnostic imaging subgroup, the difference in skill scores between PBL-based and LBL groups was not statistically significant (WMD = 1.30, 95% CI crossing zero). → Li Tingting 2022

Evidence¶

Li Tingting 2022¶

Li Tingting, Wang Weidong, Li Zhijie, Wang Hongmiao, Liu Xiaodan. (2022). Problem-based or lecture-based learning, old topic in the new field: a meta-analysis on the effects of PBL teaching method in Chinese standardized residency training.

q3 · i? · quant-synthesis · r3

Subgroup analysis of skill scores by department (Table 2): the diagnostic imaging subgroup (2 studies, 48 intervention and 48 control residents) had WMD = 1.30, 95% CI: -0.11–2.71, the only subgroup not reaching significance; "Only diagnostic imaging did not display a statistical significance in SS".

"Only diagnostic imaging did not display a statistical significance in SS, while the data from the other subgroups differed significantly compared to the LBL group"

• PBL-based teaching yields higher knowledge scores than LBL in Chinese standardized residency training — related
• PBL-based teaching yields higher skill scores than LBL in Chinese standardized residency training — related
• PBL shows no benefits for hands-on, communication, or self-directed learning skills and no advantage in operational skills for diagnostic imaging — possibly the same claim (merge candidate)
• PBL significantly improves clinical skill scores compared with lecture-based learning in medical education — a broader claim this one bears on
