q2 · i3 · causal · r2

Pretest-posttest quasi-experiment with one intact third-grade senior high school class randomly divided into treatment (N = 13) and control (N = 14) groups; the treatment received four 45-minute lessons using online activities and Yoowalk. The article reports "12.51 or 44.67%, t(25) = -4.622, p < .001, η2 = 0.460".

"a huge and statistically significant difference betwe en the treatment and the control group on the immediate posttest (IPostT) was observed, which amounted to 12.51 or 44.67%, t(25) = -4.622, p < .001, η2 = 0.460"
