MWITA-AV-2026-026 · Evidence A · P1
A 2025 randomized assignment study of urban Mumbai participants found no statistically significant test-score difference between augmented podcasts and video lectures for low- and medium-level learning items, but a significant difference for high-level learning items.
What this does not establish
The result does not establish equivalence for all topics, populations, accessibility needs or high-level learning.
Counterevidence & uncertainty
Purposive urban sampling limits generalizability; the abstract does not supply effect sizes or the direction of the high-level difference.
What would change the reading
Update with preregistered multisite replications, effect sizes and rural/disabled learner cohorts.
