The main objective of this study was to evaluate the efficacy of a Tier 2 intervention within the context of the Response to Intervention (RtI) model implemented by Spanish first- to second-grade primary school teachers to improve at-risk students' transcription skills. Teachers were instructed in the administration of a writing curriculum-based…

As gentrifying dual language (DL) schools in the United States increasingly attract students with linguistic, racial, and socioeconomic privilege, a key consideration is whether these schools are intentionally supporting the specific needs and assets of emergent bilingual (EB) students from Latinx families. This dissertation of practice examined…

This cohort-sequential study explored the working memory (WM) structures that underlie growth in mathematical word problem solving (WPS) performance in elementary school emergent bilingual children whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 in southwest U.S. school districts at Wave 1 were…

Measures of 31 Latinx students' attitudes in a Grade 5 Spanish dual language bilingual education (DLBE) program were compared with those of the same students four years prior. Twenty-one mainstream English students comprised a comparison group for the same time period. Some statistically significant changes occurred for students in DLBE related to…

Although a "semantic receptive-expressive gap" appears to be a universal feature of early bilingualism, little is known about its development. We sought to determine if the magnitude of the discrepancy between receptive and expressive standard scores changed over time in bilingual children's two languages. In this longitudinal study,…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

This study investigated the dimensionality of bilingual phonological awareness (PA) in English and Spanish by replicating a kindergarten model in Grade 1, and presents alternatives to modeling clustered data. English and Spanish tasks were analyzed from previously collected samples totaling 1,586 first grade Spanish-speaking English learners. Four…

This study examined the biliterate writing abilities and development of 25 Spanish-English Latinx children over the course of their first-grade year. As part of their regular classroom instruction, each student created 16 writing compositions over the year, once a month, eight entries each in Spanish and English. Using embedded mixed methods and a…

The United States is home to a culturally and linguistically diverse population of young children. In 2017, 10% of U.S. learners came from homes where languages other than English are spoken. Students who are learning English in addition to their native language(s) have the opportunity to become bilingual or multilingual in school. Thus, rather…

This report examines the beginning-of-year (BOY) reading performance of English learners (ELs) who attended summer school in June 2019. Summer school ELs' performance on the Texas Kindergarten Entry Assessment (TX-KEA) and iStation Indicators of Progress (ISIP) was compared to that of similar ELs who did not attend summer school. Spanish-speaking…

One relatively low-cost mechanism to assist teachers serving many English learner (EL) students and struggling readers is to hire, train, and manage paraprofessionals to provide supplementary instruction to such students. This study evaluated a program in which one district provided instructional aides to all first-grade teachers in the…

Research Findings: Universal screening is the first stage in identifying students at risk for reading difficulties within a Response to Intervention model. However, there is a lack of validated screening tools for assessing reading abilities in first-grade students from Spain. This pilot study examines the technical adequacy, classification…

This study examined teachers' adherence to the language of instruction in dual language education (DLE) programs among teachers in 19 kindergarten through 3rd grade Spanish-English two-way DLE immersion classrooms (n = 5, 90/10 model; n = 14, 50/50 model). Teachers were observed toward the beginning and end of the school year to determine…

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…

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…
