Subclaims¶

q3 i1 Multimedia design interventions led to small improvements in management of cognitive load overall (g = 0.22). → Noetel 2022 q2 i2 Personalisation and the modality effect showed large effects on cognitive load (both g = 0.62) in smaller sets of studies. → Noetel 2022 (2)

Evidence¶

Noetel 2022¶

Noetel, M., Griffith, S., Delaney, O., Harris, N. R., Sanders, T., Parker, P., del Pozo Cruz, B., & Lonsdale, C. (2022). Multimedia design for learning: An overview of reviews with meta-meta-analysis. Review of Educational Research. https://doi.org/10.3102/00346543211052329

q3 · i1 · quant-synthesis · r3

Meta-meta-analytic pooling of 68 effect sizes on cognitive load outcomes across included reviews; the pooled effect was small (g = 0.22, CI [0.04, 0.40]) and moderated by design principle (R2 = 1.00, p = 0.01).

"Overall, multimedia design interventions led to small improvements in management of cognitive load (g = 0.22, 95% CI [ 0.04, 0.40], k = 68). As with effects on learning, effects on cognitive load were moderated by the multimedia design principle"

q2 · i2 · quant-synthesis · r3

The article reports that "a small number of primary studies found large effects" for personalisation (k = 4) and modality (k = 2) on cognitive load, both g = 0.62, while larger reviews found only small effects for segmentation, signaling, and pedagogical agents.

"a small number of primary studies found large effects personalisation (g = 0.62, 95% CI [ 0.13, 1.11], k = 4; Ginns et al., 2013) and the modality effect (g = 0.62, 95% CI [ 0.27, 0.96], k = 2; Ginns, 2005)"

Related Claims¶

• Cognitive Overload Degrades Learning — the general claim this finding bears on, with the studies behind it
• Presenting words as spoken narration rather than on-screen text alongside graphics improves learning — related
• Verbal redundancy (spoken–written presentation) yields a small overall learning benefit with large between-study heterogeneity — related
• Segmentation reduces overall cognitive load during multimedia learning — related
• On-screen text that duplicates the narration of a diagram can hurt learning, but spoken–written redundancy is not harmful on average and helps over spoken-only presentation in some conditions — related
• Multimedia design principles improve learning by g = 0.38 on average across the 11 largest reviews, an effect the authors call moderate, with large differences between principles — a broader claim this one bears on
• Cognitive Load Management — related
• Segmenting multimedia instruction into learner-paced segments improves retention and transfer performance with small-to-medium effects — related
• Voice-based multimedia settings (animation+voice and picture+voice) produce better learning performance than picture+text — related
• Design principle effects are larger in system-paced and in complex media, and learner prior knowledge was not a significant moderator (p = 0.14) — related
• Meta-analytic effect sizes for cognitive-motivational techniques are substantial: multimedia d = 1.01 overall, elaborative feedback d = 0.71 recall, intrinsic integration d = 0.62 — related
• Multimedia feedback yields higher overall accuracy during practice with feedback, but without iterative improvement over scenarios — related
