- They tried to improve African kids education
- Michael Kremer suggested to use randomized controlled trial to find the most effective strategy to help kids
- They tried numerous things that did not work out
- More students books
- Flip books
- More teachers
- After some time his friend suggested that he should test deworming, which is a medical treatment not even related to education.
