If you have been paying any attention to development economics over the last 10 years, you know that education — to generalize quite a bit, how to increase school enrollment, and how to make sure children actually learn useful stuff — is one of the areas where development economists have learned the most, thanks to improved standards of causal identification.
In that spirit, two books were released just before Christmas on the topic of education in developing countries, both written by top scholars in that area. I have only browsed both books and have not yet read them carefully, but they are definitely in my to-read pile for the first half of 2014.
