Evidence¶

Adurangba Victor Oje 2026¶

Adurangba Victor Oje, Nathaniel J. Hunsu. (2026). Desktop virtual reality with scaffolded interaction and reflective explanation: effects on cognitive, motivational, and learning outcomes in engineering education. Education Tech Research Dev. https://doi.org/10.1007/s11423-026-10722-y

q3 · i3 · causal · r2

Bayesian estimation compared extraneous cognitive load between conditions. The VR + self-explanation group reported lower extraneous load ("a large effect size (d = −0.86)"), indicating fewer design-related distractions.

"For extraneous load, the posterior mean difference was β = −1.11, with a 95% credible interval of [− 1.97, −0.24] and a large effect size (d = −0.86)"

q3 · i3 · causal · r2

Bayesian estimation compared intrinsic cognitive load between conditions. The VR + self-explanation group reported lower perceived task complexity ("a very large effect size (d = −1.56)").

"For intrinsic load, the posterior mean difference was β = −1.37 (95% CI [− 1.97, −0.77]), corresponding to a very large effect size (d = −1.56)"

q3 · i? · causal · r1

Bayesian estimation compared germane cognitive load between conditions. No meaningful difference was found ("β = −0.25"), indicating the combined activity did not substantially increase learners' effort toward learning.

"In contrast, germane load did not differ meaningfully between conditions. The posterior mean difference was β = −0.25 (95% CI [− 0.72, 0.23]), with a small effect size (d = −0.34)"
