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? Segmenting multimedia instruction reduces learners' overall cognitive load compared with 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 of 56 investigations reports that "Segmentation also reduces the overall cognitive load"; no effect size value or test statistic for this outcome is printed in the available text.

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

Discussion¶

Learner Variables¶

Working Memory — outcome: instruction changes it

Segmenting multimedia instruction into learner-paced segments improves retention and transfer performance with small-to-medium effects — related
The segmenting, cognitive-load, and learning-time effects are confirmed for system-paced segmentation — related
Cognitive Load Management — possibly the same claim (merge candidate)
Letting learners pace instruction helped on complex material in one experiment, while learner control in general showed almost no effect across 18 studies — related
Segmentation Benefits Shrink With Expertise — related
Multimedia design interventions yield small average improvements in cognitive load management (g = 0.22), with personalisation and modality showing the largest effects — related
Signaling (cueing) increases learning and reduces cognitive load in multimedia — related
