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? Segmented multimedia instruction increases learning time relative to continuous presentation. → Rey 2019

Evidence¶

Rey 2019¶

Rey, G.D., Beege, M., Nebel, S., Wirzberger, M., Schmitt, T.H., & Schneider, S. (2019). A Meta-analysis of the Segmenting Effect. Educational Psychology Review, 31, 389–419. https://doi.org/10.1007/s10648-018-9456-4

q3 · i? · quant-synthesis · r?

The meta-analysis reports that segmentation "increases learning time"; no magnitude or test statistic for this outcome is printed in the available text.

"Segmentation also reduces the overall cognitive load and increases learning time."

Studies bearing on this claim¶

What does segmenting cost, and where does it add little? This table gathers the studies behind this claim and the 3 narrower claims that bear on it: 4 distinct studies (2 quant-synthesis, 1 causal, 1 associational), q2–q3, 1 of 4 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Study	Design	Effect as recorded	Bears on this claim through
Rey 2019	q3 · quant-synthesis · r?	i?	this claim
Veronica Pimenova 2026	q3 · causal · r2	i?	Easy tasks showed a floor effect across all participants and were excluded from hypothesis (qualifies)
Adesope 2012	q3 · quant-synthesis · r3	i2	Nonsegmented spoken–written presentations show a larger advantage over spoken-only present (qualifies)
Kazuki Kawamura 2025	q2 · associational · r?	i?	MOOC video engagement declines with video length, with median engagement under half the du (qualifies)

Discussion¶

Segmenting multimedia instruction into learner-paced segments improves retention and transfer performance with small-to-medium effects — the general claim this finding bears on, with the studies behind it
Cognitive Load Management — a broader claim this one bears on
The segmenting, cognitive-load, and learning-time effects are confirmed for system-paced segmentation — a narrower finding that bears on this claim
Learner control substantially increases time-on-task in animated multimedia instruction — related
