Weekly phone tutoring sessions boost learning during school closures, five-country trial finds
A study led by Oxford researcher Noam Angrist tested a low-cost intervention combining text-message nudges and a weekly 20-minute phone call from a teacher to support children's learning when schools shut down. The randomized trials, involving more than 16,000 households across India, Kenya, Nepal, the Philippines and Uganda during COVID-19 closures, followed an earlier pilot in Botswana and were published in Nature.
