This article examines the impact of within-class age differences on educational outcomes, using students' birth months in Madrid's primary schools as a natural experiment. Employing a regression discontinuity design, we analyze third-grade students to investigate these age-related effects. Additionally, we explore whether early childhood education…

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…

We explore the classification accuracy of a parent and teacher report measure, the Inventory to Assess Language Knowledge (ITALK), to screen for developmental language disorder (DLD) in bilingual children. Participants were 120 Spanish-English bilingual children with typical development (TD) and 19 bilingual children with DLD, ranging in age from…

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,…

Canadian students enrolled in either French-immersion or English-instruction programs were followed from Grades 2 to 3 (M[subscript age] = 7.8 years to 8.9 years; N = 244; 55% girls). In each grade, students completed two mathematical tasks that required oral language processing (i.e., word-problem solving and number transcoding from dictation)…

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant…

The purpose of this study was to examine associations between attendance in Georgia's Pre-K Program and children's academic and social outcomes through third grade. This report includes a sub-study that incorporates a comparison group of children who did not attend any pre-k program. This report focuses on third grade outcomes, but it also…

This report summarizes results from the Georgia's Pre-K Longitudinal Study Third-Grade Report. The study followed a representative sample of children (n=1,169) from their pre-k experience (2013-2014) through the third grade (2017-2018). Study components include: (1) Standardized child assessments that measure skills across learning domains. By…

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant…

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…

The measurement of self-regulation in young children has been a topic of great interest as researchers and practitioners work to help ensure that children have the skills they need to succeed as they start school. The present study examined how a revised version of a commonly used measure of behavioral self-regulation, the…

The purpose of this quantitative study was to examine the relationship of language proficiency (WIDA) on the performance of third, fourth, and fifth grade English language learners who were administered the Virginia Standards of Learning (SOL) assessments during the 2017-2018 assessment year. The Virginia Standards of Learning (SOL) reading and…

The purpose of this study was to assess the added value of dynamic assessment (DA) for predicting individual differences in year-end first-grade calculation (CA) and word-problem (WP) performance as a function of limited English proficiency (LEP) status. Beginning first graders (129 LEP; 163 non-LEP) were assessed on brief and static mathematics…

This article examined student literacy assessments in light of students' levels of English language proficiency. The study supported the hypotheses that a student's level of language proficiency positively predicted their DIBELS Composite score at the beginning, middle, and end of kindergarten by utilizing a simple linear regression. An ANOVA…

The current study examined the proficiency of Israeli adolescents in reading single words in English, which is taught as a foreign language, and what language skills predict individual variability. Parallel measures of word reading, phonology, decoding, morpho-syntax and vocabulary in Hebrew and English were administered to 217 adolescents in 8th…
