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…

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…

Despite substantial cross-national interest in remedial programming as a way to support low-achieving students, evidence of its effectiveness is rare, particularly in low-income and/or crisis-affected contexts. In this article, we present experimental evidence of the impact of a remedial tutoring program on academic outcomes from a two-level…

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…

This study aims to examine whether a maths-unrelated reading intervention can improve children's mathematical performance and to compare the effects of maths-related and maths-unrelated reading interventions. Furthermore, this study examines whether the effects of reading interventions are moderated by individual differences, including gender,…

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…

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…

There is a burgeoning body of evidence on the average impacts of educational programs. Yet, for many local decision makers, because impacts can vary across sites, the question of whether a certain program will work in their particular district or school remains. This article addresses the question of the generalizability of large-scale average…

Early mathematical learning for students that exhibit typical gifted characteristics, including precocity and sophisticated math ability, should have opportunities to expand their thinking capacities through enrichment and/or advanced coursework that allows them to reach their full potential. Effective programming interventions allows for…

This study compared students' performance on Istation, a computer-based progress-monitoring tool, and easyCBM, a paper-pencil progress-monitoring tool. Participants included 106 students in Grades K-6 from a rural school in New Mexico. Teachers in these grade levels administered both assessments three times during the school year. Results…

Michigan's Great Start Readiness Program (GSRP) is a state-funded pre-K program that serves at risk four-year-old children across the state. Utilizing longitudinal data from 1,394 children in a mid-sized urban school district, we conducted regression analyses and piecewise linear growth models to examine the growth trajectory of GSRP children and…

Background or Context: Dual language education aims to foster the development of bilingualism, biliteracy, sociocultural competence, and academic skills in all school subjects. Early correlational research suggests that participation in dual language education is associated with higher achievement. Recent studies leveraged more comprehensive sets…

The utility of homework and its impact on academic achievement has been an ongoing debate for more than 100 years. To date, there is no rigorous experimental research to show whether, and the extent to which, variations in the amount of homework assigned can impact the academic performance of elementary school students. In this study, 440…

Recent research links disparities in children's language-related brain function to poverty and its correlates. Such disparities are hypothesized to underlie achievement gaps between students from low-income families and more advantaged peers. Interventions that improve language-related brain function in low-income students exist, but evaluations…
