We measure practitioner teacher beliefs and show they update accurately towards identifying "what works," revealing the power of embedded learning to drive change on the front lines

Some of the effectiveness-enhancing tests generate large gains in learning at very minimal cost, such as engaging caregivers more, ranking in the upper percentiles of the cost-effectiveness literature.

We include two types of tests:
➡️ Effectiveness-enhancing. Add to see if the program is more effective.
➡️ Cost-reducing. Reduce to see if the program = as effective.
We often test the former, but rarely the latter. We find cost-reducing tests yield consistent efficiency gains

➡️ Learning is iterative and cumulative. We show how randomized trials can be at once rigorous, while also rapid and regular. We put together over 12 A/B tests which we ran starting in 2020, once every school term, in Botswana.
