MWITA-YF-2026-017 · Evidence A · P1
A cluster-randomized trial in 291 Kenyan public pre-primary schools found a curriculum-integrated smartphone learning program produced effects of 0.534 SD overall, 0.450 SD in numeracy and 0.449 SD in literacy after 13 months.
What this does not establish
The effect belongs to the integrated curriculum-and-teacher program, not learning apps generally or unsupervised smartphone use.
Counterevidence & uncertainty
Effects attenuated after midline and implementation context matters.
What would change the reading
Update with longer follow-up, cost, subgroup and scale evidence.
Primary routes
