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 VF-high students significantly outperformed VF-low (d = 0.644) and DI (d = 0.648) students on the conceptual knowledge posttest. → Thomas C. Braas 2025

q3 · i2 · causal · r2

Randomized experiment with 152 secondary students in four conditions (PF, VF-high, VF-low, DI); ANCOVA on conceptual knowledge showed a significant condition effect, F(3, 140) = 3.078, p =.030, η2p = 0.062, with "students in the VF-high condition significantly outperformed" VF-low and DI in Bonferroni-corrected post-hoc tests.

"students in the VF-high condition significantly outperformed their counterparts in the VF-low conditions ( p =.014, 95% CI [0.11, 1.18], Cohen’s d = 0.644) and DI (p =.010, 95% CI [0.19, 1.26], Cohen’s d = 0.648) on conceptual knowledge acquisition."
