Subclaims¶

q3 i? Pooled analysis of six studies found no significant difference between PBL and conventional learning methods in critical thinking/knowledge assessment (p = 0.29), with very high heterogeneity (I2 = 93%). → Manuaba Ida Bagus Amertha Putra 2022

q3 · i? · quant-synthesis · r2

Meta-analysis of six articles evaluating critical thinking/knowledge in PBL versus conventional groups, using a random-effect model because heterogeneity p < 0.10; the authors report "no significant difference between PBL and conventional learning methods (p = 0.29)" and I2 = 93%, indicating good heterogeneity.

"We found that for developing critical thinking, PBL was a better program. Unfortunately, there is no significant difference between PBL and conventional learning methods (p = 0.29) (Fig 2)."

Related Claims¶

• PBL shows no statistically significant advantage for self-directed learning in first-year students (p = 0.34), with the pooled fixed-effect estimate inclined toward the conventional method — related
• In first-year medical students, PBL showed no significant difference from non-PBL teaching in critical thinking, problem-solving, or self-directed learning — possibly the same claim (merge candidate)
• PBL is not statistically superior to conventional teaching for problem-solving in first-year students (p = 0.47), with the pooled effect tending toward conventional teaching — related
• PBL shows significant advantages in critical thinking compared with traditional education or team-based learning in nursing and clinical student populations — related
• Subgroup analyses by intervention duration and region reduce heterogeneity only for interventions longer than six months and Western countries, without significant PBL differences in any subgroup — related
• PBL and conventional instruction produce similar learning outcomes in postgraduate medical education (pooled mean difference 0.13%, 95% CI -6.74 to 7.00) — related
