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 i3 Children receiving GEMS education scored significantly higher on the overall PSSSE at post-test than control children (t = 3.5, p = .002, Cohen's d = 1.41). → Unal 2018

q2 · i3 · causal · r1

Semi-experimental pre-test/post-test control group study of 25 six-year-olds (11 experimental, 14 control) in Malatya kindergartens; post-test total PSSSE compared by independent samples t test, t = 3.5, p = .002, effect size "1.41" (Cohen's d). The experimental mean was 2.72 vs control 2.50.

"When Table 5 was examined, the change observed in the problem solving scores of the children receiving education within the scope of GEMS Education before and after the application was found to be higher compared to the control group"
