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.

q3 i1 Among low prior knowledge learners, learning gains were significantly higher in the EDT condition than in the CS condition (r = .16). → Siswa van Riesen 2018

q3 · i1 · causal · r2

Subgroup analysis of 63 learners classified as low prior knowledge (maximum two of nine correct on the Archimedes' principle pre-test part). Mann–Whitney follow-ups showed "significantly higher learning gains for low prior knowledge learners in the EDT condition compared to low prior knowledge learners in the CS condition" (r = .16).

"An independent samples Kruskal–Wallis test showed a significant difference between the conditions, H(2) = 6.54, p = .038. Follow-up Mann–Whitney analyses showed significantly higher learning gains for low prior knowledge learners in the EDT condition compared to low prior knowledge learners in the CS condition, U = 115.50, z = 2.438, p = .015, r = .16."
