q3 i3 Across 11 studies (1575 participants), pooled GRAT scores statistically exceeded IRAT scores with SMD = 2.05 (95% CI 1.64–2.46) under a random-effects model. → Ngoc Phan Nguyen 2020

q3 · i3 · quant-synthesis · r2

Meta-analysis pooling GRAT–IRAT differences from 11 studies of healthcare-professions students (1575 participants) in a random-effects model, reporting "SMD = 2.05" with very high heterogeneity (I2 = 95%).

"the GRAT scores were statistically greater than IRAT scores when TBL was applied in a random-effects model (standardized mean difference (SMD) = 2.05, 95% confidence interval (CI) = 1.64 ~ 2.46, pheterogeneity < 0.001 I2 = 95%)"

Discussion¶

Related Claims¶

• Nursing-only TBL subgroups show a larger GRAT–IRAT difference (SMD = 2.368) than other health-professions subgroups, though the subgroup test is not significant — a narrower finding that bears on this claim
• TBL improves team readiness assurance test scores compared to individual tests — possibly the same claim (merge candidate)
• In both TBL formats, tRAT and iSAT scores significantly improve over preceding iRAT scores — related
• Students' IRAT scores were consistently poorer than their TRAT scores, suggesting team collaboration benefits team test performance — possibly the same claim (merge candidate)
