q2 · i1 · design · r3

Independent-samples t test comparing GEQ post-play ratings of students playing NNG 1 (N = 642, grades 4–6) and NNG 2 (N = 526) in the 2014 large-scale study. The article reports "effect sizes ranged from close to medium (d = 0.36) to close to large (d = 0.7)", with Competence non-significant (p = 0.509).

"Results from an independent t test showed that there were significant differences between game experiences in all dimensions, except Competence with effect sizes ranged from close to medium (d = 0.36) to close to large (d = 0.7)."

• Students' perceived usability of the game declined significantly across lessons while focused attention, aesthetics, and satisfaction remained stable — related
