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 i? A Kruskal–Wallis test found no significant differences in conceptual knowledge gains between the EDT, CS, and CM conditions. → Siswa van Riesen 2018

Siswa van Riesen, Hannie Gijlers, Anjo Anjewierden, Ton de Jong. (2018). Supporting learners' experiment design. Education Tech Research Dev (2018) 66:475–491. https://doi.org/10.1007/s11423-017-9568-4

q3 · i? · causal · r2

Between-condition comparison in the randomized experiment (n = 86 analyzed): the Kruskal–Wallis test on knowledge gains found "No significant differences were found between the conditions" (H(2) = 2.96, p = .228). Equivalence was not tested.

"To determine whether learners who worked with the EDT gained more conceptual knowledge than learners in the control conditions, an independent samples Kruskal–Wallis test was performed. No significant differences were found between the conditions, H(2) = 2.96, p = .228."
