Subclaims¶

q2 i3 After treatment, the experimental group's preposition accuracy scores increased significantly while the control group's did not, with a large effect size (d = 4.28). → Ahmed Ali Saleh Al Ajmi 2015

q2 · i3 · causal · r1

Quasi-experiment with 25 experimental and 25 control students in intact classes; independent samples t-test on immediate post-test scores. The experimental group reached M = 7.40 (SD = 2.22) versus control M = 1.08 (SD = 1.12), "the effect size was large ( d= 4.28)".

"For the immediate post-test, however, a significant difference arose as the experimental group’s scores increased from the pre-test scores (M =7.40, SD =2.22), while the control group’s scores showed no significant increase (M =1.08, SD =1.12) , (t(35.41) =12.73, p =.00 , two-tailed), and the effect size was large ( d= 4.28)."
