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.
q2 i? In a series of studies by Mayer and colleagues, narrated PowerPoints with synced auditory and visual information were more meaningful for immediate and future learning outcomes than auditory-only or visual-only information, with the worst outcomes when out of sync. → John Hattie 2025

q2 · i? · review · r2
The review reports, citing Mayer and colleagues (2019), a series of studies on multimedia learning: synced audio-visual narration beat single-channel presentation, and "the worst outcomes occurred when the auditory and visual information were out of sync". No effect sizes are printed.
"For example, in a series of studies, Mayer and colleagues (2019) found that narrated PowerPoints in which auditory and visual information were synced were more meaningful for immediate and future learning outcomes than when just auditory or visual information was given."
Discussion¶
Related Claims¶
- Matching modality by conveying complementary information through auditory and visual channels increases retention, transfer, and engagement — related
- Presenting words as spoken narration rather than on-screen text alongside graphics improves learning — related
- Voice-based multimedia settings (animation+voice and picture+voice) produce better learning performance than picture+text — 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
- Redundant on-screen text impairs learning when it competes with a visualization, though written text duplicating narration alone can help — related
- Concrete visual presentation can convey only concrete, simple meanings; abstract and general meanings are conveyed by language — related
