How Big Are Effect Sizes in International Education Studies?

• In Event: Forty Years of Education Production Functions in Comparative Education: Reflections and Advances

Proposal

The first presentation will consider the effect sizes of 234 educational interventions in 51 low- and middle-income countries. The analysis identifies a median effect size of 0.10 standard deviations on learning and 0.07 standard deviations on access among randomized controlled trials. The presentation will conclude with policy implications, including how to situate new findings within current knowledge and design new studies with enough statistical power to identify effects.
