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? Even with the strictest control for self-selection, positive causal effects appeared for declarative and contextual knowledge. → Tani 2022
Evidence¶

Tani, M., Manuguerra, M., & Khan, S. (2022). Can videos affect learning outcomes? Evidence from an actual learning environment. Education Tech Research Dev. https://doi.org/10.1007/s11423-022-10147-3
q3 · i? · causal · r1
Viewers-only analysis (Table 4) comparing students who watched presentation A with those who watched presentation B, reducing observations to about 25% of the original sample. Contrasts were "+ 18.1 points" (p = .091) and "+ 34.3 points" (p = .077).
"The contrast analysis (Model 3) indicates substantive differences for declarative knowledge (+ 18.1 points out of 100 and p-value of 0.091) and contextual knowledge (+ 34.3 points and p-value of 0.077)"
