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.

q3 i? Tenth-grade students taught quadratic functions with GeoGebra software and guided discovery worksheets achieved significantly higher achievement scores than control students taught with textbook and paper-pencil methods. → Övez 2018

q3 · i? · causal · r2

Pretest-posttest control group experiment with 62 tenth-grade students randomly assigned to groups (31 each). Independent samples t-test on achievement scores: test group gain 2.65 (pretest 0.41 to posttest 3.06) versus control gain 1.1 (0.38 to 1.48), "a significant difference between achievement score averages".

"According to “t” test results, it was observed that there was a significant difference between achievement score averages [t = -5.61; p=.001<.05]. This finding indicates that for students’ achievement level computer –aided education applied in test group was more effective than the technique of text book, paper, and pencil used in the control group."
