Evidence¶

Yao Gege 2025¶

Yao Gege, Zhang Junlong, Soh Kim Geok, Bai Xiaorong, Xiao Wensheng, Anuar Mohd Ashraff Mohd, Bao Lixia. (2025). Effective implementation of the Sport Education Model in physical education: A meta-analysis of participant and intervention characteristics. PLoS One. https://doi.org/10.1371/journal.pone.0331228

q3 · i3 · quant-synthesis · r2

Subgroup meta-analysis by intervention frequency. Two lessons per week showed "Effect size = 1.820" (95% CI 0.486–3.154, P = 0.008), the largest frequency effect.

"SEM with an intervention frequency of 2 lessons/week showed a significant large positive effect (Effect size = 1.820; P = 0.008)"

q3 · i1 · quant-synthesis · r2

Subgroup analysis for ≤1 lesson/week found a significant small effect (ES = 0.484, 95% CI 0.021–0.847, P = 0.009).

"SEM with an intervention frequency of ≤1 lesson/week demonstrated a significant small positive effect on students' physical education learning (Effect size = 0.484; P = 0.009)"

q3 · i? · quant-synthesis · r2

Subgroup analysis for >2 lessons/week found no statistically significant effect (P = 0.979, ES = 0.003); equivalence was not tested.

"SEM did not achieve statistical significance for students with >2 lessons/week intervention (P = 0.979)"
