Student performance in Sub-Saharan Africa is tragically low. We study the importance of teacher subject knowledge for student performance in this region using unique international assessment data for sixth-grade students and their teachers. To circumvent potential bias due to unobserved student...

We present experimental evidence on the impact of a technology-aided after-school instruction program on learning outcomes in middle school grades in urban India, using a lottery that provided students with a voucher to cover program costs. A key feature of the program was its ability to...

This study is the first to explore long-run trends of numeracy for the 1820-1949 period in 165 countries, and its contribution to growth. Estimates of the long-run numeracy development of most countries in Asia, the Middle East, Africa, America, and Europe are presented, using age-heaping...

EdTech which includes online education, computer assisted learning (CAL), and remote instruction was expanding rapidly even before the current full-scale substitution for in-person learning at all levels of education around the world because of the coronavirus pandemic. Studies of CAL...

We study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Africa. We use data from an international large-scale assessment in 14 countries that include individual-level information on student achievement and...

Reducing the gender gap in education is a primary goal for many countries. Some major challenges for many girls include the distance to school, their safety when commuting to school, lack of agency, and deep-rooted cultural norms. In Zambia, we studied the impact of providing a bicycle to a...

We investigate how the intensity of Ramadan affects educational outcomes by exploiting spatio-temporal variation in annual fasting hours. Longer fasting hours are related to increases in student performance in a panel of TIMMS test scores (1995–2019) across Muslim countries but not other...

We use a panel survey of ∼19,000 primary-school-aged children in rural Tamil Nadu to study 'learning loss' after COVID-19-induced school closures, and the pace of recovery after schools reopened. Students tested in December 2021 (18 months after school closures) displayed learning deficits of...

Students in low-income contexts often lack guidance in their career decisions which can lead to a misallocation of educational investments. We report on a randomized field experiment conducted with 1715 students in rural Cambodia and show that a half-day workshop designed to support adolescents...

Recent studies of US elite exam schools have yielded the startling conclusion that such schools improve neither educational achievement nor longer-term educational outcomes. Is the same true for exam schools elsewhere? The system in Turkey is ideal for investigating this question. There,...
