Dual language immersion (DLI) programs were developed in the U.S. with the expressed goal of supporting intercultural connections, bilingualism, biliteracy, and respect for diversity. However, these programs are still influenced by broader social ideas and power dynamics. From this perspective, this year-long ethnographic case study uses a…

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…

This research uses a descriptive quantitative statistical design to examine campus-level results from the State of Texas Assessments of Academic Readiness (STAAR). The focus is on describing the achievement disparities between campuses that implemented Transitional Bilingual Education (TBE) programs and those implementing Dual Language (DL)…

This paper addresses the interactional dynamics of one bilingual, two-way immersion classroom where children came from diverse linguistic, cultural, racial, and socioeconomic backgrounds. Based on an ethnographic discourse analytic study of one kindergarten TWI classroom, I analyze interactional data using participant frameworks as the unit of…

This study explored the development of oral narrative retell proficiency among Mandarin Chinese-English dual language immersion (DLI) learners in Utah. The study compared the younger and the older DLI learners' oral narrative retelling production in order to provide information regarding the Mandarin narrative developmental trend of the DLI…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

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…

Amidst the current climate surrounding bilingual education in the U.S., this study looked critically at the ways language education policies informed bilingual education as language was constructed and performed in a dual language bilingual, Spanish-English, third-grade classroom.

Using the 2.4-million-word written Spanish subsection of the Corpus of Utah Dual Language Immersion, collected from a large-scale standardized writing assessment of K-12 Spanish second language (L2) students, this study focuses on lexical complexity as operationalized by three measures: lexical diversity, lexical density, and lexical…

The two-way immersion dual language education program design includes the use of language labels to identify students as either the English speaker or the speaker of a language other than English. This paper examines four focal student and two teacher interviews to consider the ways in which the idea of a 'language expert' transpired during…

The rapid growth of Mandarin Chinese and English dual-language (DL) programs and the differences between these two languages have fostered the need to investigate the early literacy performance of young students in a Mandarin/English DL program. This study used the interactive transfer framework (Chung et al., 2019) to understand the Mandarin and…

This article describes the practical application of an innovative bilingual preschool program that involves two-way immersion of both English and Chinese in classrooms. This has not been written about extensively, especially in the context of early childhood classrooms in Asian countries. The primary goal of the two-way immersion kindergarten is…

This three-article dissertation examined how policy choices in three key policy areas -- initial enrollment, service provision, and reclassification -- impact English learner (EL)-classified students. The first article examined the national landscape of state statutes, regulations, and state education agencies' (SEA) guidance that support…

The present study examined the effect of children's enrollment in U.S. dual-language immersion (DLI) programs in first grade on English development across five years, using the Early Childhood Longitudinal Study, Kindergarten Class of 2011 (ECLS-K:2011) database. Propensity score matching was used to create comparable groups of DLI and non-DLI…

Indiana dual-language immersion (DLI) programs have grown exponentially in the last 5 years as a result of state policies, related state funding, and increasing pressure for public schools to have a specialized presence amidst school choice provisions. Principals work with their communities to identify the DLI model they will adopt, student…
