Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

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…

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)…

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…

Literature provides consistent evidence that there is a strong relationship between language proficiency and math achievement. However, research results show conflicts supporting either an increasing or a decreasing longitudinal relationship between the two. This study explored a longitudinal data and adopted quantile regression analyses to…

The United States faces high demand for science, technology, engineering, or mathematics (STEM) professionals and a scarce supply of individuals who pursue STEM careers, especially minority populations in the U.S with proficiency in a language other than English. The primary goal of this research was to determine the impact of use of Spanish in…

This study used a family-centered ecological lens to examine predictive relations among fathers' and mothers' language acculturation, parenting practices, and academic readiness in a large sample of Mexican American children in preschool (N = 880). In line with prior early childhood research, parent language acculturation was operationalized as…

Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students' outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL…

The present study used data from the Early Childhood Longitudinal Study--Kindergarten Class of 1998-1999 to examine whether the relationship between first-grade word-reading and reading-comprehension growth through eighth grade was different for language-minority learners (LMs) versus native English-speaking students (NEs). Among high word…

The purpose of this dissertation is to contextualize the measurement of the HLE for Spanish-speaking Latino families. This goal will be accomplished by using a series of HLE items to characterize the potential heterogeneity in the HLE of Spanish-speaking families as well as to examine differences in the HLE based on caregiver's language…

We utilize a within-group framework to understand the association between childcare type and the language-use and vocabulary of second-generation Latino immigrant children. The sample was drawn from a study of a suburban/rural immigrant community to study the role of home experiences on the early language and literacy of young Latino preschoolers…

The analysis of 21,409 participants of the Early Childhood Longitudinal Study-Kindergarten cohort focused on home and school factors sought to understand the level of reading mastery that children experienced throughout elementary school and Grade 8 by relating home language use, timing of oral English language proficiency, and the provision of…
