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 i2 Treatment students significantly outperformed control students on two novel post-test essay tasks (electronic ankle bracelet, life choices), with ηp2 = 0.08 and 0.07 — smaller than the taught-task effect. → Kristoffer Larsson · Klas Andersson 2025

q3 · i2 · causal · r2

One-way independent ANOVAs on two post-test-only essay tasks not used in either intervention group, testing transfer to novel content. Effects were significant with ηp2 = 0.08 and 0.07; the article notes "even though the effects were smaller" than on the taught voting-age task.

"The results show significant effects of the variation theory teaching intervention on students' ability to alternate between points of view on these tasks also, F (1, 90) = 7.38, MSE = 0.55, p < 0.05, ηp2 = 0.08; F (1, 90) = 7.28, MSE = 0.55, p < 0.001, ηp2 = 0.07."
