This paper presents evidence of the effects of dual language immersion (DLI) programs on the academic outcomes of students in elementary grades. Leveraging enrollment lotteries from four cohorts of DLI applicants across 10 oversubscribed programs, analyses estimate the intent-to-treat effect of access to bilingual education on reading and math…

Understanding how to intensify an intervention is critical to implementing response-to-intervention (RtI), a tiered, problem-solving framework to deliver evidence-based interventions per student needs. Research and practice guidelines provide conflicting recommendations for delivering math interventions (i.e., treatment intensity) within RtI. The…

Despite policy relevance, longer-term evaluations of educational interventions are relatively rare. A common approach to this problem has been to rely on longitudinal research to determine targets for intervention by looking at the correlation between children's early skills (e.g., preschool numeracy) and medium-term outcomes (e.g., first-grade…

The purpose of this study was to study the impact on student performance due to participation in the Catapult Learning Intervention program in the Mathematics services offered in a religious non-public school system in the Northeastern United States from grades K-2. Student scaled scores from the NWEA MAP assessments administered at the beginning…

Children in Florida who will be 4 years old on or before September 1st of the school year are eligible to attend a Voluntary Prekindergarten Education Program (VPK), provided by either the public school districts or other private providers, regardless of family income. There are several different VPK programs, including Head Start, Title I, and…

Underperformance in mathematics has been an issue that plagues the education system in Jamaica. Studies in first world countries have shown that enrichment programs, including Mathematics Enhancement Programmes (MEPs,) have been positively impacting attainment in mathematics. This quasi-experimental research design study investigated the impact of…

Although proponents suggest that universal social-emotional learning (SEL) programs promote academic achievement, few studies have directly tested these outcomes under routine conditions in schools. Forty first-grade classrooms participated in an effectiveness trial in which schools (N = 13) were randomly assigned to implementation of a universal…

The purpose of this study was to analyze the impact on student performance due to participation in the Catapult Learning Intervention program in the Mathematics and Reading services offered in a religious non-public school system in the Northeastern United States from grades K-2. Scaled scores from the NWEA MAP assessments administered at the…

The purpose of this mixed methods study was to analyze a First Grade Summer Jumpstart program after the first year of implementation to evaluate the effectiveness of the program to positively impact academic achievement in reading and math for first grade students. In order to achieve this overall objective, the following research questions framed…

Early mathematics achievement sets the stage for a range of important academic and career outcomes. As efforts to improve elementary mathematics instruction have increased, efforts to better understand how students develop mathematics knowledge and why students respond to mathematics instruction have also emerged. Given known correlations between…

This report focuses on Harlingen Consolidated Independent School District's 2022-2023 implementation of "My Math Academy" with Kindergarten, 1st, and 2nd grade students across its 17 elementary schools. Students' program usage has been associated with significant improvements on CIRCLE Progress Monitoring Assessment System (pre-K) and on…

With over two decades of research showing a close association between working memory (WM) and maths performance, WM training has been suggested as one way to supplement conventional remedial instructions. Although initial findings were promising, recent reviews have found that training typically resulted in WM improvement but no transfer to maths…

Summer numeracy interventions have become standard educational practice across a range of jurisdictions, but there is a paucity of evaluations of those interventions across international settings. We employ a quasi-experimental evaluation of voluntary summer numeracy programs for 569 attendees and 2,193 comparison students in grades 1-3, conducted…

This report focuses on the 2023-2024 implementation of "My Math Academy" at Epic Charter Schools in Oklahoma. "My Math Academy" was first used with a small pilot group of students and educators at the charter school network in school year 2022-2023, and based on the initial positive results, the implementation of the program…
