Targeted instruction is one of the most effective educational interventions in low- and middle-income countries, yet reported impacts vary by an order of magnitude. We study this variation by aggregating evidence from prior randomized trials across five contexts, and use the results to inform a new randomized trial. We find two factors explain…

School-wide positive behavior interventions and supports (SWPBIS) is widely implemented across the United States. Evidence suggests that SWPBIS, when implemented with fidelity, has a significant and positive impact on schools, including lower suspensions and higher reading and mathematics achievement. A critical component of this research is…

Given the well-documented relation between executive functioning (EF) and math skills in preschool, there is a surprising lack of evidence on early intervention approaches that have successfully, and consistently, impacted both EF and math skills. To confront this gap in the literature, Study 1 explored why an established EF intervention impacted…

This study evaluated the effectiveness of faithful use of Imagine Math, a computer adaptive math intervention for elementary students in grades three through five. To achieve this objective, the researcher compared the math achievement growth as measured by the NWEA MAP math assessments from fall 2021 to spring 2022 between the treatment group and…

Meeting a tremendous need for K-8 schools and educators, this timely book outlines core principles for counteracting the disruptions of the pandemic and recovering from learning loss. The authors present a holistic approach to responsive literacy instruction to support all students' academic and social-emotional growth, now and in the years to…

In this paper we examine academic recovery in 12 mid- to large-sized school districts across 10 states during the 2021-22 school year. Our findings highlight the challenges that recovery efforts faced during the 2021-22 school year. Although, on average, math and reading test score gains during the school year reached the pace of pre-pandemic…

This study evaluated the feasibility of the Knowledge, Language, and Inquiry (K.L.I.) intervention, designed to support Grades 3-5 multilingual students classified as English learners (ML-ELs) in building content knowledge, language skills, and reading comprehension through inquiry-based small-group instruction. Feasibility was examined across…

Background/Context: Despite increasing school enrollment, significant literacy gaps persist in developing countries, with many children unable to read by age 10. This paper evaluates "M'ap Li Net Ale," a comprehensive intervention aimed at improving early-grade reading skills in Haiti, a context characterized by limited government…

The Investing in Innovation (i3) Fund was established by the American Recovery and Reinvestment Act of 2009, which called on the U.S. Department of Education (ED) to provide student achievement awards to local education agencies and nonprofits with a record of improving student achievement. ED set priorities for the program and specified them in…

We present findings from a randomized controlled trial of "Descubriendo la Lectura" (DLL), an intervention designed to improve the literacy skills of Spanish-speaking first graders, who are struggling with reading. DLL offers one-on-one native language literacy instruction for 12 to 20 weeks to each school's lowest performing…

We examined the effectiveness of a researcher-provided reading intervention with 484 fourth graders with significant reading difficulties. Students were randomly assigned to one year of intervention, two years of intervention, or a business-as-usual comparison condition (BAU). Students assigned to two years of intervention demonstrated…
