How to organize education online when students cannot go to school? To help answer this question, EPIE researchers Igor Asanov, Anastasiya-Mariya Asanov, Francisco Flores and Guido Buenstorf, joint with our colleagues Tom Åstebro and Mathis Schulte (HEC Paris), Bruno Crépon (ENSAE), David McKenzie (World Bank) and Mona Mensmann (University of Cologne), tested various light-touch interventions to improve students' educational process and knowledge outcomes. Results of this study, which was part of the INCHER project Showing Life Opportunities, have now been published in the Proceedings of the National Academy of Sciences (PNAS).
