Building on previous research, researchers in this study evaluated the impact of several targeted instruction programs on the learning outcomes of primary school students in Ghana’s public schools. Researchers found significant improvements in numeracy and literacy on average; of the four interventions, in-school and after-school remedial lessons delivered by Teacher Community Assistants had the largest impact on pupil achievement.

Researchers evaluated the long-run effects of temporary contact between individuals from different regions during military service on interregional attitudes and national identity sentiments among former Spanish male conscripts. Overall, conscription outside of one’s region of origin led to positive and long-lasting effects on interregional sentiments, and increased the sense of national identity among conscripts from regions with strong secessionists movements.

Researchers evaluated whether providing low-stakes diagnostic tests and feedback to teachers led to improved student learning outcomes in India. They found that teachers in intervention schools exerted more effort when observed in the classroom but students in these schools performed no better on independently-administered tests than students in schools that did not receive the program.

Researchers evaluated the impact of access to a package of free dental services on employment levels for urban residents of Santiago, Chile. Results found that participants with access to these services had better dental health, and that self-esteem and short-term employment increased among women, particularly those who had previously been missing front teeth or with lower levels of self-esteem.

Researchers evaluated whether an alternative teacher incentive scheme, providing rewards based on the performance of all students, could help reduce dropout and improve student math learning. Introducing the pay-for-percentile incentive scheme reduced overall student dropout rates. However, these reductions were driven almost entirely by students at intervention schools with math textbooks. Among schools with math books, the incentive scheme also improved the math achievement for higher performing students.
