Subclaims¶

q2 i? Subgroup analysis found low heterogeneity for interventions longer than six months and Western-country comparisons (I2 = 0%), but high heterogeneity for shorter interventions (I2 = 96%) and Asian countries (I2 = 95%), with no statistical difference between PBL and conventional methods in any subgroup. → Manuaba Ida Bagus Amertha Putra 2022

q2 · i? · quant-synthesis · r1

Subgroup analysis of critical thinking/knowledge studies regrouped by intervention duration (≤ 6 months vs > 6 months) and countries (Asia vs. western), assessed with random- and fixed-effect models. Heterogeneity fell to I2 = 0% only for >6 months and Western subgroups; no subgroup showed a significant PBL difference.

"The studies with the duration intervention at more than six months and learning method comparison in western countries subgroup were found to have low heterogeneity ((I2 = 0% (might not be important)). However, high heterogeneity scores were found in the studies with duration intervention less than six months (I2 = 96%) and learning method comparison in Asian countries subgroup (I2 = 95%)."

Related Claims¶

• PBL shows no statistically significant advantage over conventional learning for critical thinking/knowledge in first-year medical students (p = 0.29) — related
• Meta-regression finds discipline, country, year, and learner identity do not significantly explain heterogeneity in TBL-versus-PBL effects — related
• Publication type, course type, educational level, and experimental duration did not significantly moderate the effect of context-based learning on academic achievement — related
• TBL effects on theoretical knowledge and practical skills are larger in interventions lasting more than 4 weeks — related
• Intervention duration significantly moderates Gen-AI's effect on HOT, with the strongest effects at 8–16 weeks (ES = 0.759) and weaker effects for shorter (0.494) and longer (0.372) interventions — related
• Subgroup results: CBL ranks best for clinical curricula and across educational backgrounds, while PBL ranks best for basic courses, developing countries, and operational skills — related
