Subclaims¶

q3 i3 Eighth-grade students receiving POESPBEE scored significantly higher on the ASTE than the control group at post-test and follow-up, with large effect sizes (η2=0.22 and η2=0.31). → Calis 2020

q3 · i3 · causal · r2

Independent samples t-test comparing the experimental (n=34) and control (n=28) groups' ASTE scores after a ten-week quasi-experimental application. The article reports η2=0.22 at post-test and η2=0.31 at follow-up, both above 0.14, indicating a large effect size.

"there was a significant difference between the groups’ post-test scores (t (60)= -4.05; p<.05) and follow-up test scores (t (60)= -5.25; p<.05) in favor of the experimental group."
