    Improving Primary Education in the Democratic Republic of the Congo: End-Line Results of a Cluster-Randomized Wait-List Controlled Trial of Learning in a Healing Classroom

    RLOsWe used a cluster-randomized, wait-list controlled trial to examine impacts of a school-based social-emotional learning intervention on Congolese students and teachers. Seventy-six school clusters in two groups (A and B) were randomized to treatment or control. The groups differed in geographic location, accessibility, exposure to violence, and external donor investment. We estimated causal impacts in Group A, tested whether those impacts were replicated in Group B, and conducted sensitivity analyses on the pooled sample. Pooled analyses had higher statistical power and were therefore more likely to represent the true average impacts of the program. Improvements in students’ perceptions of school predictability and in addition and subtraction, geometry, and reading performance were specific to Group B. Only the effect on addition and subtraction remained significant in the pooled analysis. Improvements in teachers’ sense of accomplishment were found in Group A and remained significant in the pooled analysis. We detected no impacts on other outcomes. School-based interventions embedding social-emotional learning principles into the academic curricula are a promising but not yet proven approach to improving children’s outcomes in low-income countries affected by war

    RLOshis article examines the effects of one year of exposure to “Learning to Read in a Healing Classroom” (LRHC) on the reading and math skills of second- to fourth-grade children in the low-income and conflict-affected Democratic Republic of the Congo. LRHC consists of two primary components: teacher resource materials that infuse social-emotional learning principles into a reading curriculum and collaborative school-based teacher learning circles to exchange information about and solve problems in using the teacher resource materials. To test the impact of LRHC on children's reading and math skills, 40 school clusters containing 64 schools and 4,465 students were randomized to begin LRHC in 2011–2012 or to serve as wait-list controls. Hierarchical linear models (students nested in schools, nested in school clusters) were fitted. Results indicate marginally significant positive impacts on children's reading scores (dwt = .14) and geometry scores (dwt = .14) but not on their addition/subtraction scores. These results should be treated with caution given the reported significance level of p < .10. The intervention had the largest impacts on math scores for language minority children and in low-performing schools. Research, practice, and policy implications for education in low-income conflict-affected countries are discussed.

    HIT-COVID, a global database tracking public health interventions to COVID-19

    The COVID-19 pandemic has sparked unprecedented public health and social measures (PHSM) by national and local governments, including border restrictions, school closures, mandatory facemask use and stay at home orders. Quantifying the effectiveness of these interventions in reducing disease transmission is key to rational policy making in response to the current and future pandemics. In order to estimate the effectiveness of these interventions, detailed descriptions of their timelines, scale and scope are needed. The Health Intervention Tracking for COVID-19 (HIT-COVID) is a curated and standardized global database that catalogues the implementation and relaxation of COVID-19 related PHSM. With a team of over 200 volunteer contributors, we assembled policy timelines for a range of key PHSM aimed at reducing COVID-19 risk for the national and first administrative levels (e.g. provinces and states) globally, including details such as the degree of implementation and targeted populations. We continue to maintain and adapt this database to the changing COVID-19 landscape so it can serve as a resource for researchers and policymakers alike
