Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i2 Post-test achievement of the cooperative learning with models group (CLMG) was significantly higher than both the STAD-only group and the control group after ANCOVA adjustment. → Ataman Karaçöp 2016

q2 · i2 · causal · r2

Quasi-experimental pretest-posttest non-equivalent comparison-group study with 70 first-year science teacher education students in three groups (CLMG N=24, CLG N=24, CG N=22). ANCOVA with pre-EcAT as covariate showed a significant group difference, "F (2,66) =7.459", with effect size f = 0.47 interpreted as high.

"Analysis results in Table 3 showed that there was a statistically significant difference between mean post ECAT scores of the study groups (F (2,66) =7.459; p < .05). In addition, the calculated effect size value (f = 0.47) was interpreted as the effect of the experimental application was high (f > 0.4)."
