Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

Purpose: We investigated the efficacy of "Story Champs" for improving oral language in third-grade Spanish-English bilingual children with developmental language disorder (DLD). Method: We implemented a concurrent multiple-baseline across-participants single-case design with four bilingual Spanish-English third-grade students with DLD.…

In the U.S., the EL student population in public schools continues to grow and it raises the question on how to effectively instruct and prepare these students to achieve academic proficiency. The purpose of this quantitative study is to determine if and to what extent there is a quantitative link between gains from 2nd to 3rd grade where the…

The purpose of this qualitative descriptive study was to explore how kindergarten through third--grade public school educators in diverse classrooms described the influence and challenges of multicultural teaching strategies, with a focus on content integration and knowledge construction, on learners' English language acquisition in Arizona. Two…

We present findings across three randomized trials of "Descubriendo la Lectura" (DLL), an intervention designed to improve literacy skills of Spanish-speaking first graders struggling with reading. DLL is a one-to-one Spanish-language literacy program lasting 12-20 weeks offered to a school's lowest performing emerging bilingual first…

English learners (ELs) in K-12 schools must acquire English while simultaneously mastering content knowledge. Educational technology may support students' learning through the affordance of individualized language practice. The current randomized controlled trial intervention study examined the effects of Rosetta Stone Foundations software on…

In spring 2019, without controversy or fanfare and without violating the voter mandate of Proposition 203, emergent bilinguals in Arizona were once again granted unrestricted access to dual language bilingual education after nearly 20 years. The policy change was accomplished through a seemingly small piece of legislation that reduced the daily…

Although current and former English Learner (EL) or "ever-EL" students comprise one of the fastest-growing K-12 populations, we still know relatively little about the factors that influence their college-going. Using Perna's seminal college-going model as a launching point, we propose a policy-driven empirical approach to explore how…

The authors evaluate the success of Arizona's program for English Learners (ELs) twelve years after the implementation of Proposition 203 to determine whether it meets the "third prong" test of Castañeda v. Pickard (1981), which requires a demonstration of the effectiveness of a program after its implementation. This study is a follow-up…

Background: Making mathematics connections between home and school can have a positive impact on students' mathematics learning. This is particularly important for students whose experiences and perspectives are underrepresented in school curricula. Although there is evidence for how crucial it is to make connections between mathematics…

Two consequentially related education policy topics in the United States are kindergarten entry assessments (KEAs) and the growing number of students who are "English learners" (ELs). In this study, I compared the content of, and home language use policies for six state KEAs, all of which were comprised of items from the GOLD®…

We present case studies of elementary school leaders in an Arizona district with a large enrollment of Latinx Spanish-speaking students who qualify for English language development services. The Culturally and Linguistically Diverse Leadership dimensions are used as a lens to examine how school leaders navigate Arizona's restrictive language…

Purpose: We investigated four theoretically based latent variable models of word learning in young school-age children. Method: One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and…

The development of academic English proficiency and the time it takes to reclassify to fluent English proficient status are key issues in English learner (EL) policy. This article develops a shared random effects model (SREM) to estimate English proficiency development and time to reclassification simultaneously, treating student-specific random…

This study was prompted by the Arizona Department of Education's (ADE) interest in learning more about the progress of English learner students toward English proficiency in the early grades. The study examined, for the 2013/14 kindergarten cohort in Arizona, the English language proficiency of non-native English speaker students and their English…
