This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language…

There are large gaps in reading skills by family income among school-aged children in the United States. Correlational evidence suggests that reading skills are strongly related to the amount of reading students do outside of school. Experimental evidence testing whether this relationship is causal is lacking. We report the results from a…

This paper presents evidence confirming the validity of the RD design in the Reading Recovery study by examining the ability of the RD design to replicate the 1st grade results observed in the original i3 RCT focused on short-term impacts. Over 1,800 schools participated in the RD study over all four cohort years. The RD design used cutoff-based…

In this study, we used a quasi-experimental, longitudinal design to examine the English language arts (ELA) and mathematics test scores of emergent bilinguals (EBs) in DLBE 50:50 models versus English as a second language (ESL) models in Indiana over four academic school years. With a focus on the midwestern U.S., we bring attention to a…

Two-way dual language (DL) classrooms enroll students of two different language backgrounds and teach curriculum in both languages. I estimate the effect of attending a DL school on student achievement using school choice lotteries from Charlotte-Mecklenburg School District in North Carolina, finding local average treatment effects of 0.04 and…

In this paper, we report results from a multisite, student-level randomized controlled trial that examined the impact of the Building Assets, Reducing Risks (BARR) model on ninth-grade students. The BARR model is a comprehensive, strength-based approach that uses eight interlocking strategies to build intentional staff-to-staff, staff-to-student,…

Parents play an important role in creating home language environments that promote language development. A nonequivalent group design was used to evaluate the effectiveness of a community-based implementation of LENA Start™, a parent-training program aimed at increasing the quantity of adult words (AWC) and conversational turns (CT). Parent-child…

Meeting the unique educational and social needs of newcomer students (students who were born outside of the United States and have arrived in the country within the past three years) is an ongoing challenge for educators and community stakeholders across the country. This resource toolkit is intended to help educators and other stakeholders…

California State University, San Bernardino (CSUSB) and the Riverside County Office of Education (RCOE) were awarded an Investing in Innovation (i3) Development grant in 2015 to investigate the impact of an early education mathematics program on English Learner students at two rural school districts in Riverside, CA. Teaching English Learners…

Objective: College students with attention deficit/hyperactivity disorder (ADHD) are at increased risk for numerous educational and psychosocial difficulties. This study reports findings from a large, multisite randomized controlled trial examining the efficacy of a treatment for this population, known as ACCESS -- Accessing Campus Connections and…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

We use admissions lotteries to estimate the effects of large-scale public preschool in Boston on college-going, college preparation, standardized test scores, and behavioral outcomes. Preschool enrollment boosts college attendance, as well as SAT test-taking and high school graduation. Preschool also decreases several disciplinary measures…

The National Math + Science Initiative (NMSI) is a nonprofit organization committed to improving educational outcomes that traces its roots back to the early 1990s. NMSI's College Readiness Program (CRP) is a long-standing program with the goal of promoting STEM education in high schools to improve students' preparation for college. The three-year…

Many states seek to increase the education levels of their early childhood education (ECE) workforce to improve the quality of care for children. Oregon encourages all ECE workforce members to sign up for a career lattice, a career pathway system that helps them determine goals related to increasing their education. The state also offers…

Studies have shown that math skills in early childhood are uniquely and strongly predictive of later outcomes across a range of domains and well into adulthood, including the likelihood of graduating from high school and college completion. The Making Pre-K Count and High 5s studies were designed to rigorously test the short- and long-term effects…
