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 i3 Providing students with videos in addition to existing content produced a strong, significant pooled effect (g = 0.88), with 88% of true effects expected to be helpful. → Noetel 2021

q3 · i3 · quant-synthesis · r3
Meta-analysis of 34 randomised comparisons (n = 64 effect sizes) where one condition received existing content plus videos. The review reports "a strong, significant effect of providing students with supplemental videos (g = 0.88, 95% CI [0.62, 1.13])" with high heterogeneity (I²₂ = 0.55, I²₃ = 0.37).
"There was a strong, significant effect of providing students with supplemental videos (g = 0.88, 95% CI [0.62, 1.13], n = 64, k = 34)."
Discussion¶
Related Claims¶
- Replacing existing teaching with video produces small improvements in student learning in higher education (g = 0.28) — related
- Evidence of publication bias exists, but the pooled video effects are robust to it — related
- Video replacing static media (e.g., text) benefits learning more than video replacing a teacher — related
