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? The effect of instructional method on conceptual understanding depends on students' prior knowledge level: a statistically significant interaction was found, F(3, 97) = 2.762, with η² = 0.079. → Leppink 2012

Evidence

Leppink 2012

Leppink, J., Broers, N. J., Imbos, T., van der Vleuten, C. P. M., & Berger, M. P. F. (2012). Self-explanation in the domain of statistics: an expertise reversal effect. Higher Education, 63, 771-785. https://doi.org/10.1007/s10734-011-9476-1

q3 · i? · causal · r2

Two-way ANOVA (instructional method × prior knowledge group) on conceptual understanding scores (scale 0-10) in the randomized experiment with first-year bachelor students. The article prints the interaction statistic and g2 = 0.079 (η², in the 0.04-0.13 band) but the authors treat main effects as uninterpretable given the interaction pattern.

"Although the hypothesis of differential instructional method effects for the different prior knowledge groups was not confirmed for propositional knowledge, it was confirmed for conceptual understanding. We found a significant interaction effect, F(3, 97) = 2.762, p\ .05 ( g2 = 0.079)."
