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 i? Post-test Science and Nature Problems subscale scores did not differ significantly between the experimental and control groups (Mann Whitney-U U = 70.00, p = .698). → Unal 2018

Evidence

Unal, M., & Saglam, M. (2018). Examination of the effect of the GEMS program on problem solving and science process skills of 6 years old children. European Journal of Educational Research, 7(3), 567-581. https://doi.org/10.12973/eu-jer.7.3.567

q2 · i? · causal · r1

Mann Whitney-U test on post-test SNP subscale scores in the 25-child pre-test/post-test control group study; Table 4 prints U = 70.00, p = .698, with experimental mean 1.81 and control mean 1.88. Equivalence was not tested.

"When Table 4 was examined, it was determined that there was no significant difference in the Mann Whitney -U test results about the post -test mean scores of the children in the control and experimental groups for the subscales of the Problem Solving Scale in Science Education."
