In Bangladesh, researchers conducted a randomized evaluation to test whether helping selected farmers set up demonstration plots could increase awareness in the community about a new rice variety by triggering information exchanges through new interactions. Demonstration plots comparing new versus traditional seed varieties improved farmers’ knowledge about the new rice variety. The new interactions induced by the demonstration plots were most effective for farmers who were least socially connected before the intervention was delivered.

Researchers partnered with the Chilean Ministry of Education to evaluate the impact of pre-packaged classroom materials and standardized directions for teachers on teaching quality and student learning. The program improved student learning outcomes substantially, with equal benefits for both boys and girls, and particularly positive impacts for children from higher-income backgrounds.
