Making electricity and learning materials in students’ native language more widely available in schools may be beneficial to student learning, but existing evidence is sparse. Researchers conducted a randomized evaluation to test the impact of school electrification, delivered alongside mixed-language digital educational materials, on student exam scores and pass rates. They found that neither increased electricity access nor learning material in their native language improved students’ academic performance.

Researchers conducted a randomized evaluation on measuring the impact of celebrity Twitter endorsement for a child immunization campaign on the public’s opinion and behavior towards immunization. Celebrity endorsement increased Twitter engagement with the immunization campaign, primarily when celebrities authored messages themselves and did not explicitly cite credible public health sources. Celebrity endorsement led to increased communication and knowledge about health behaviors in individuals’ communities, though there was no impact on an individual’s immunization decisions for their children.
