Spanish-speaking students constitute the largest subgroup of emergent bilingual (EB) students in the United States. Using longitudinal data on a nationally representative sample of Spanish-English EBs, we explore profiles of English reading trajectories and how early individual differences (i.e., early Spanish reading and English oral proficiency)…

This study examined the role of parents' early home language use in the English reading development of emergent bilinguals (N = 3,058) and how their relations are moderated by children's oral English language proficiency using longitudinal data from kindergarten to eighth grade (ages 6-15 years). Results from multi-group latent basis growth models…

This secondary analysis study examined patterns, predictors, and outcomes of dual language learners' (DLLs') development in Spanish and English. Research Findings: Latent profile analysis identified three groups of DLLs: Balanced Bilinguals (54%), English-Dominant Bilinguals (25%), and Spanish-Dominant Bilinguals (21%). These groups had fairly…

This study examines the relationship between English Learner (EL) classification, language program type, and peer victimization using nationally representative data from the Early Childhood Longitudinal Study- Kindergarten Class of 2011. Leveraging a sample of 9,562 children, this study investigates whether Dual-Language programs serve as a…

Using kindergarten up to fourth-grade data from the Early Childhood Longitudinal Study (2010--2011 cohort), we investigated systematic variability in English language learners' (ELLs; n = 303) mathematics growth as well as relations of kindergarten language growth and working memory (WM) to ELLs' mathematics growth. Using growth mixture modeling,…

This study provides estimates for the impact of centre-based care participation during pre-kindergarten on Latino children's academic readiness skills at kindergarten-entry. Using the ECLS-K:2011 dataset, findings indicate that Latino children who participated in centre-based care during their pre-kindergarten year had significantly higher English…

Prior research has shown that English learner (EL) classification is consequential for students; however, less is known about how EL classification affects student outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using a national data set (Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 or…

The present study tested the postulation that "knowledge begets reading, which begets knowledge." Using Random Intercepts Cross-Lagged Panel Models (RI-CLPM), we analyzed a U.S. nationally representative data set to examine the directionality and magnitude of the longitudinal relation between domain knowledge (operationalized as science…

The present study examined the effect of children's enrollment in U.S. dual-language immersion (DLI) programs in first grade on English development across five years, using the Early Childhood Longitudinal Study, Kindergarten Class of 2011 (ECLS-K:2011) database. Propensity score matching was used to create comparable groups of DLI and non-DLI…

In this brief, we use a nationally representative sample of ever-English learners (ELs; N = 783) to examine relations between EL concentration within classrooms and reading growth between kindergarten and Grade 5. Piecewise growth models were used to estimate relations for four developmental periods (K-1, Grades 1-2, Grades 2-3, and Grades 3-5).…

The early elementary years are foundational for future academic achievement, and, as the number of Latino students in U.S. schools continues to rise, more attention has been given to the academic performance of these young learners. Yet little is known about the cognitive skills, such as executive function (EF), that may underlie Latinos' academic…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

Background: Socioeconomic gaps in children's academic and social skills are large upon Kindergarten entry (von Hippel, Workman, and Downey 2018; Reardon 2011; Reardon and Portilla 2016). Preschool programs may yield particularly large benefits to low-income students and racially minoritized groups and may be promising for reducing inequalities…
