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…

Introduction: This article investigates an early STEM family engagement program offered during the pre-kindergarten (pre-k) year. Pre-k is an important juncture for community organizations to support children's STEM engagement and parental involvement in informal STEM learning. We evaluated a program called Teaching Together STEM, which offers a…

Purpose: There is limited research on the writing of young Spanish-English bilinguals and their writing in both languages. In the current study, we addressed whether written syntax features differed by language (English and Spanish) and varied as a function of grade level, English learner status, and instructional program (dual or English…

This study evaluated the feasibility of the Knowledge, Language, and Inquiry (K.L.I.) intervention, designed to support Grades 3-5 multilingual students classified as English learners (ML-ELs) in building content knowledge, language skills, and reading comprehension through inquiry-based small-group instruction. Feasibility was examined across…

Background: School closures and service disruptions related to the COVID-19 pandemic significantly impacted students' postschool transitions. Students with disabilities who were also members of historically marginalized groups including immigrant students, multilingual students, students of color, and those experiencing poverty, were…

We investigated the dimensionality and relations between L1 (a speaker's first language) and L2 (a speaker's second language) writing skills in narrative and informational genres and higher order cognitive skills--inference, perspective taking, and comprehension monitoring--for Spanish-English dual language learners in primary grades. Dimensions…

The aim of this study was to explore how the Coding as Another Language (CAL) curriculum, developed by Boston College's DevTech Research Group and utilizing the ScratchJr app, impacted students' computational thinking, coding skills, and reading comprehension. To accomplish this, the research team randomly assigned thirteen schools in a…

This study explored the relations between parental formal education, residential mobility, and children's school readiness in a sample of 509 Head Start children, 30% of whom were Spanish-speaking Dual Language Learners (DLLs). Additionally, it explored whether the relations between these demographic factors and school readiness varied as a…

Using a randomized controlled trial, we examined the impact of a teacher professional learning (PL) program on English as a Second Language (ESL) teachers' use of evidence-based instructional strategies for multilingual learners, collaboration with classroom teachers, and incorporation of Latino multilingual learners' cultural wealth into their…

Despite frequent reliance on teacher and parent ratings of children's behavior for multi-informant assessment, agreement between teachers' and parents' ratings is low. This study examined the predictive utility of teacher and parent ratings for children's self-regulatory outcomes (i.e., executive function, continuous performance task) in four…

We investigated spelling errors in English and Spanish essays by Spanish-English dual language learners in Grades 1, 2, and 3 (N = 278; 51% female) enrolled in either English immersion or English-Spanish dual immersion programs. We examined what types of spelling errors students made, whether they made spelling errors that could be due to…

Many educators and policymakers look to two-way dual language immersion as one of the most promising options to close achievement gaps for English learners. However, the programs' effectiveness depends on the quality of their implementation. This article reports on a large-scale study of the implementation of dual language immersion across a…

Research Findings: Children's oral language skills lay the foundation for later literacy and can be fostered through responsive conversations with teachers. However, such conversations are rare in preschool, particularly between teachers and dual language learners (DLLs), or students who speak a minoritized language at home. DLLs benefit when…

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…

Using a nationally representative sample of 3- and 4-year-old Spanish-speaking dual language learners (DLLs) attending Head Start (N = 654), this study examined whether mean levels of and variability in peers' English receptive vocabulary skills were associated with DLLs' English and Spanish receptive vocabulary skills in the spring. In addition,…
