The effect of teacher training and community literacy programming on teacher and student outcomes

Motivated by extremely low levels of basic reading skills in sub-Saharan Africa, we experimentally evaluate two interventions designed to enhance students’ early-grade literacy performance in rural Mozambique: a relatively light-touch, scalable teacher training in early-grade literacy including the provision of pedagogical materials, and teacher training and materials in conjunction with community-level reading camps. Using data from 1,596 third graders in 160 rural public primary schools, we find no evidence that either intervention improved teachers’ pedagogical knowledge or practices or student or teacher attendance following two years of implementation. There are some weak positive effects on student reading as measured by a literacy assessment, primarily observed in a shift away from scores of zero, and these effects are consistent across arms. Our findings are aligned with the growing consensus that more intensive school- and/or community-based interventions are required to meaningfully improve learning.

How much do our neighbors really know? The limits of community-based targeting

How much do our neighbors really know? The limits of community-based targeting

Social assistance programs in developing countries often rely on local community members to identify potential beneficiaries. As community members may observe neighbors’ welfare, their reports may capture transitory shocks better than the proxies typically observable by a centralized policy implementer. To test this, we conduct a lab-style experiment in Central Java, in which participants rank other community members’ welfare, using benchmarks that vary in sensitivity to transitory shocks, and target small cash transfers. We find little evidence that community-held welfare information better reflects transitory shocks and find that targeting decisions mostly depend on perceived differences in overall wealth.

Whole maize flour could enhance food and nutrition security in Malawi

Whole maize flour could enhance food and nutrition security in Malawi

Maize is the staple cereal in Malawi, with a daily per capita consumption of 383 g (dry matter basis), primarily consumed in the form of nsima, a thick porridge. We combined a milling experiment with focus group discussions (FGDs) to provide insights into mass and nutrient losses during maize grain dehulling and maize flour consumption patterns in rural Malawi. Milling batches (30 kg) of four maize grain varieties were dehulled at three abrasive disk dehullers under controlled conditions. The impact of maize variety and dehuller design on mass and nutrient losses during dehulling was statistically significant (p < 0.05), with a mean mass loss of 28.1 ± 5.7%, and nutrient losses of 9.8 ± 1.9% for protein, 61.7 ± 2.0% for zinc, and 47.7 ± 3.6% for iron. Six FGDs conducted in rural areas of Lilongwe District revealed a preference for refined flour due to convenience and cultural norms, despite the nutritional benefits of whole grain flour, which was recognized for its ability to provide satiety, particularly during periods of maize scarcity. Participants also highlighted switching between flour types based on seasonal maize availability, social stigma associated with whole grain flour, and awareness of nutrient losses during dehulling. Given Malawi’s precarious food insecurity situation, transitioning from dehulled maize flour nsima to whole maize flour or less refined nsima, is imperative. Our study findings can have food and nutritional savings for other southern Africa countries where the dehulling is a common practice.
