Cheaper (and more effective) by the dozen: Evidence from 12 randomised A/B tests optimising tutoring for scale - What Works Hub for Global Education This paper presents iterative randomised A/B tests of a mobile phone numeracy tutoring programme to optimise efficiency and scalability.

Tutoring school children is effective, but hard to scale. Researchers @noamangrist.bsky.social, @ccullen.bsky.social, & @janicalapati.bsky.social used a novel A/B testing approach to enhance cost-effectiveness and scalability of a program in Botswana. πŸ”— Read the new paper: https://bit.ly/3WYniJn

I'd love to help make BlueSky one of the places where young scholars introduce themselves and their work to the world.

If you're a PhD student whose work at least partially focuses on economics of education or education policy, reply to this thread and I'll highlight your work.

Encouraging evidence for faster, rigorous learning in the social sector.

Grateful for @kbeegle.bsky.social 's thoughtful deep dive on our new paper & a related studyβ€”we find that a couples training program in Rwanda, meant to reduce IPV, unexpectedly increased it, raising important questions on backlash & spillovers.
