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? After 16 course hours, the experimental (PBL) group scored significantly higher than the control (traditional) group on the mixtures achievement posttest. → Üce and Ates 2016

q2 · i? · causal · r1

Pretest-posttest control group experiment with 24 students per group at an Anatolian High School; independent-samples t-test on posttest means (control 17,920 vs experimental 22,040) showed "a significant difference in favor of the experimental group" (p<0.05). No effect size is printed.

"In consequence of the statistical analysis of posttest realized after the application, a significant difference in favor of the experimental group was found in the achievement test on mixtures topic. (p<0.05, Table:2)."
