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…

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…

Many studies examine how bilinguals and monolinguals differ in their executive function abilities at one time-point or cross-sectionally. Fewer examine how these groups of children may differ over time. Using nationally representative data obtained from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), this…

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…

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…

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)…

Despite much research examining whether bilingual individuals demonstrate superior executive function (EF) skills compared to monolinguals, the purported bilingual advantage remains controversial. One potential reason for discrepant findings across studies examining the bilingual advantage is the difficulty in matching monolingual and bilingual…

Although quality center-based child care is helpful in promoting school readiness for dual language learners (DLLs), little is known about the nonparental child care that young DLL children experience. DLL status is often confounded with immigrant status, ethnicity, and poverty. Using nationally representative data from the Early Childhood…

Previous research examining the reading achievement of immigrant children has often grouped English learners into one broad category, referred to as ELs, thereby creating an "either-or" dichotomy regarding whether or not these students need school language supports. The present study examined the theoretical contention regarding the…

Using the Early Childhood Longitudinal Study, Kindergarten Cohort, this study examines the role that bilingualism plays in children's academic developmental trajectories during their early school years, with particular attention on the school environment (N = 16,380). Growth-curve results showed that despite starting with lower math scores in…

This longitudinal study examined the effect of all-day kindergarten programs on the academic achievement of students from racial language minority and low socioeconomic class. The study employed a series of 3-level longitudinal multilevel analyses using a nationally representative database, the Early Childhood Longitudinal Study (ECLS). The study…

This study investigates change in the home language environment of Language Minority (LM) learners between kindergarten and eighth grade, drawing on data from the National Center for Education Statistics' Early Childhood Longitudinal Study-Kindergarten (ECLS-K) Cohort. The analytic sample included 1,538 children whose parents reported a language…
