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 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…

The present research examines the role of morphological awareness in reading comprehension of high school emergent bilinguals. As an increasing number of research studies contribute to our understanding of morphological awareness, i.e. the ability to reflect on and manipulate morphologically complex derived words, we are better able to appreciate…

This study investigated the relationship between elementary classroom (N = 50) reading activities in Year 1 and reading performance (i.e., passage comprehension, letter-word identification, and word attack) 1 year later for English language learners (ELLs; N = 270). A cross-classification hierarchical model indicated that compared to other reading…

This longitudinal study examined the role of oral proficiency on English reading comprehension, as measured with elicited narratives using a wordless picture book, "Frog Where are You?". The sample consisted 102 English language learners, including both Spanish and Cantonese speakers. Narrative samples were collected in the winter of…

We examined theoretical issues concerning the development of reading fluency and language proficiency in 390 English Language Learners (ELLs,) and 149 monolingual, English-as-a-first language (EL1) students. The extent to which performance on these constructs in Grade 5 (i.e., concurrent predictors) contributes to reading comprehension in the…

It has long been theorized, if not exhaustively researched, that bilingualism and biliteracy are beneficial in promoting linguistic and academic gains; but the operationalization of these constructs is confounding. In the current study, the authors worked with 118 Spanish-English bilingual Latina/o students and investigated whether Spanish-English…

The development of English language learners (ELLs) was explored from kindergarten through eighth grade within a nationally representative sample of first-time kindergartners (N = 19,890). Growth curve analyses indicated that, compared to native English speakers, ELLs were rated by teachers more favorably on approaches to learning, self-control,…
