q3 i? Viewers had a higher probability of answering test questions correctly than non-viewers. → Tani 2022

Evidence¶

Tani 2022¶

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

Quasi-experimental analysis of 568 first-year economics students (22,720 question-level observations) using generalised linear mixed models. Model 1 estimated a marginal effect of watching the presentation of "0.0206" (p = .007), described as "a 2% increase in the probability of answering correctly".

"watching the presentation emerges as having a strong positive effect on the probability of answering the questions correctly in the mid-term test. The point estimate is not small (a 2% increase in the probability of answering correctly, keeping all other variables fixed)"

Discussion¶

Related Claims¶

• Multimedia presentation effects are strongest for procedural knowledge (technical and contextual) — related
• Watching a pertinent multimedia presentation has a positive effect on evaluative knowledge — related
• Viewers-only analysis shows positive effects on declarative and contextual knowledge — a narrower finding that bears on this claim
• No overall multimedia effect on problem-solving performance in vector calculus: graphs did not significantly improve correctness — reports the opposite
