Subclaims¶

q3 i? Pooled effect sizes for all five DREEM subscales (perceptions of learning, teachers, academic self-perceptions, atmosphere, social self-perceptions) favored PBL over LBL with statistical significance. → Qin Yongjie 2016

Evidence¶

Qin Yongjie 2016¶

Qin Yongjie, Wang Yungui, Floden Robert E. (2016). The Effect of Problem-Based Learning on Improvement of the Medical Educational Environment: A Systematic Review and Meta-Analysis. Medical Principles and Practice. https://doi.org/10.1159/000449036

q3 · i? · quant-synthesis · r1

Meta-analysis of subscale scores reported in all six included studies (335/338 per subscale). The quote lists three of five subscales; the article also reports atmosphere (WMD 1.76) and social self-perceptions (WMD 1.19), all favoring PBL. The authors note prior individual studies were inconsistent on four subscales, whereas "our meta-analysis found that the PBL method was superior to the LBL method in all subscales of DREEM".

"The pooled effect sizes for students' perceptions of learning (WMD 2.84, 95% CI 2.23–3.45, p < 0.0001), students' perceptions of teachers (WMD 1.77, 95% CI 0.92–2.61, p < 0.0001), students' academic self-perceptions (WMD 1.06, 95% CI 0.61–1.50, p < 0.00001)"
