q3 i? The studying rate advantage of videos over illustrated texts was 37%, 20%, and 3% at the 25th, 50th, and 75th percentiles, indicating the greatest benefit for slower readers. → Mikko Haavisto 2026

Mikko Haavisto, Tomi Jaakkola. (2026). Fifth graders study videos faster than illustrated texts: Studying rate, review strategies, and learning implications. Instructional Science. https://doi.org/10.1007/s11251-026-09817-z

q3 · i? · causal · r2

Percentile comparison of studying rates from the within-subjects screen-recording study, reported in the Discussion. The article attributes the fast video studying rate to children's infrequent use of navigation options, with an average of only 1.5 backward-button clicks during the initial pass.

"the studying rate in the videos was 37%, 20%, and 3% faster for 25th, 50th, and 75th percentiles compared to the illustrated texts, respectively. This shows that the videos were especially beneficial for the slower readers."
