The rising demand for dual-language immersion (DLI) programs, which offer core instruction in two languages from early grades onward, has raised questions about program design and access. We leverage the rapid expansion of DLI schools across the U.S. state of Utah to estimate effects of DLI program availability on the academic achievement of…

Success in mathematics contributes to children's future career and lifelong financial security. There have been reports that dual-language education conveys academic advantages in mathematics achievement, although there is debate. This study aimed to investigate whether dual-language education benefits children's mathematics achievement and…

Purpose: This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Method: Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n =…

The population of Spanish-speaking preschoolers in the United States continues to increase and there is a significant need to develop psychometrically sound early language and literacy screening measures to accurately capture children's ability in Spanish. In this paper, we describe the innovative design and calibration process of the new…

This study is part of a larger effort to investigate linguistic features of assessment items that might explain differential performance of English learners on science assessments. An analysis of a large set of multiple-choice items suggested two features that held promise in reducing the performance gap: the presence of contrast words and the…

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…

A primary objective of development is to build a knowledge base. To accumulate knowledge over time and experiences, learners must engage in productive processes, going beyond what is explicitly given to generate new knowledge. Though important to accumulating knowledge, these processes are also easily disrupted. Individuals often depend on surface…

Theory of Mind (ToM), as a relevant aspect in children's socio-cognitive development, has been widely studied. Some results have suggested that bilingual children have an advantage over their monolingual peers in development of ToM. However, there is less research regarding the predictive role of ToM in performance of oral and reading…

The standard scoring of the CLASS PreK produces three domain scores that are widely used in research, practice and policy. Despite these domains being based on developmental theory and research, limited empirical evidence exists for the three-domain structure as operationalized in the CLASS PreK. Using the 2009 and 2014 Head Start Family and Child…

Purpose: This study aimed to describe change in dual language learners' (DLLs) morphosyntactic skills from kindergarten to first grade based on a sentence repetition task in English and Spanish. Methods: The sample included Spanish-English speaking children (n = 25). Investigators employed a repeated measures analysis of variance with one…

We describe research results and lessons learned from a laboratory/ classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

The goal of this study was to examine written translation as a means to: a) build on the theoretical notion that a bilingual individual's languages are shared; b) operationalize biliterate ability; and c) propose a new method of assessment for culturally and linguistically diverse students. Drawing from the fields of cognitive psychology and…

Research Findings: This study aimed to (a) provide an in-depth description of the frequency and type of language interactions that children who are low income and/or dual language learners (DLLs) experience in their classrooms and (b) examine whether differences exist in children's language experiences based on children's DLL status and level of…

In this correlational study, we analyzed data from 71 Spanish-English biliterate students in grades 3 (n=21), 4 (n=23), and 5 (n=27) with the goal of investigating the applicability of the Simple View of Reading (Gough & Tunmer, 1986; Hoover & Gough, 1990) in English and in Spanish for this population. The simple view posits that decoding…

Research has demonstrated that students in dual-language immersion programs perform as well as, or better than, their peers in core academic content areas by late elementary school. The extent to which immersion education fosters bilingualism, however, has received less attention in the literature. Using data from a four-year efficacy study of…
