Overview
Updated 2 hours agoMore than 200 million children each year lose school time to disease, conflict and climate shocks. A five-country study in Nature shows a weekly phone call from a tutor kept primary students learning through COVID closures. Cost: about $11 per child.
Students who got calls plus text prompts learned about three times more than in typical education programs, per the randomized trials. The results give governments a proven, scalable tool for keeping education going when classrooms close.
Why it matters
When disease, conflict or climate closes schools, governments now have a proven way to keep 200 million children learning at about $11 each.

Historical Context
2 moments from history that rhyme with this story — and how they unfolded.
Teaching at the Right Level movement (2000s-present)
India's Pratham developed a model that groups children by learning level rather than grade, then teaches targeted material. Randomized trials across India and Africa showed large gains and governments adopted the approach.
TaRL became one of the most widely replicated education interventions in low-income countries.
Demonstrated that level-targeted instruction works where grade-based curricula fail.
Phone tutoring applies the TaRL mechanism - assessing each child and teaching at their level - through a single remote tutor, extending a proven pedagogy to emergencies.
Ebola school closures and radio education (2014)
When Ebola shut schools across Sierra Leone, Liberia and Guinea, education ministries turned to radio broadcasts to keep children learning. Programs aired structured lessons for months with limited interactivity and little evidence of impact.
Radio kept some learning continuity but had no rigorous evaluation; many children returned to school far behind.
Set a precedent for mass-media emergency education but left governments without proven models.
The phone-tutoring study addresses the same emergency-education problem with a two-way channel, and it is the first multi-country trial to show large, measurable gains.
