Subclaims¶

q3 i1 Across 83 randomised comparisons, swapping other teaching for video significantly improved learning with a small pooled effect (g = 0.28), with about half of true effects helpful and 19% potentially unhelpful. → Noetel 2021

Evidence¶

Noetel 2021¶

Noetel, M., Griffith, S., Delaney, O., Sanders, T., Parker, P., del Pozo Cruz, B., & Lonsdale, C. (2021). Video Improves Learning in Higher Education: A Systematic Review. Review of Educational Research, 91(2), 204–236. https://doi.org/10.3102/0034654321990713

q3 · i1 · quant-synthesis · r3

Multilevel random-effects meta-analysis of 83 randomised comparisons (pooled n = 166 effect sizes) swapping video for existing teaching. The review reports "a significant positive effect on student learning (g = 0.28, 95% CI [0.14, 0.42])" with substantial unexplained heterogeneity (I²₂ = 0.32, I²₃ = 0.55).

"Overall, replacing other teaching with video had a significant positive effect on student learning (g = 0.28, 95% CI [0.14, 0.42], n = 166, k = 83)."

Studies bearing on this claim¶

Does learning from video beat the teaching it replaces or adds to, and for which goals? This table gathers the studies behind this claim and the 6 narrower claims that bear on it: 2 distinct studies (1 quant-synthesis, 1 causal), q2–q3, 1 of 2 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.

Discussion¶

Related Claims¶

• Evidence of publication bias exists, but the pooled video effects are robust to it — related
• Adding supplementary video to existing teaching produces strong learning benefits (g = 0.88) — related
• Video replacing static media (e.g., text) benefits learning more than video replacing a teacher — a narrower finding that bears on this claim
• Video benefits learning only when its interactivity matches or exceeds the comparison condition — related
• Video is more effective for teaching skills than for transmitting knowledge — a narrower finding that bears on this claim
• Dosage relationship: more assigned Edpuzzle videos associated with larger gains — related
• No dose-response effect: video benefits do not systematically increase with intervention length — related
