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 Post-test Material Usage Problems subscale scores differed significantly between groups (t = -4.4, p = .000, Cohen's d = 1.77), favoring the experimental group. → Unal 2018

q2 · i3 · causal · r1
Independent samples t test on post-test Material Usage Problems subscale of the PSSSE in the same 25-child pre-test/post-test control group study; the table prints t = -4.4, p = .000, Cohen's d = 1.77, with experimental mean 2.51 vs control 2.14.

Discussion¶
Related Claims¶
- GEMS education produced higher post-test overall problem solving scores in science education than the control program (d = 1.41) — a broader claim this one bears on
- Within the GEMS group, problem solving scores improved significantly from pre-test to post-test on both subscales and the total — related
- No significant post-test difference between groups on the Science and Nature Problems subscale — related
