The purpose of this study is to explore the statistical nature of the linguistic interdependence hypothesis (Cummins, 1976, 2017) in the spring of 2nd grade of students in foreign language immersion programs. Specifically, the interdependent relationship between L2 language proficiency levels and L1 reading academic performance in an environment…

The amount of language input bilingual children receive influences their language acquisition. This three-year quasi-longitudinal study determined the extent home language input influences measures of expressive and receptive English vocabulary among Spanish-English school-age bilingual children. The study also determined whether a relationship…

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 present dissertation brings together research on heritage language acquisition and bilingual education and makes inroads into the limited research on heritage language development in school-aged bilingual children. This study explores how bilingual education, patterns of exposure, and lexical frequency shape adolescent Spanish heritage…

Language separation policies in two-way bilingual education (TWBE) reflect ideologies of double monolingualism (Heller, 1995) and ignore the sociolinguistic realities of bi/multilingual students (García & Lin, 2017). This case study investigates the design and implementation of collaborative multilingual identity text projects (Prasad, 2018)…

This critical classroom study of language oppression draws from the notion of existing inequalities based on power relations in education research, as addressed in a critical ethnography. This critical classroom study explores the cases of two recent immigrant students, "Manuel" and "Malena," on the -U.S.-Mexican border near El…

The native language use in the target language classroom has recently gained the attention of second language acquisition research. This study analyzes such issue in the context of Dominican university students, ranging from 18 to 35 years old, studying in an English immersion program, who have been speaking their native language, namely, Spanish…

This paper sets out to show how a trilingual teaching sequence delivered primarily in minority L2 Basque can foster not just development of oral presentation skills in Basque, but also in L1 Spanish and L3 English. We set out to show that such a trilingual teaching intervention, based on the principles of integrated teaching of languages and…

Ideologies regarding what is "good" teaching undergird common teaching practices and pedagogical decisions, which may support and/or run counter to the broader policy environment in which they occur (Gibson, 1998). Drawing from a six-month ethnography of 10th-grade newcomer students from Mexico and their teachers in a Central Texas…

This article examines translanguaging that occurs in and as a community. Expanding the notion of translanguaging, we conceptualize "community translanguaging" as collaborative meaning-making among children, their family and community members, and their collective semiotic resources. Using a family literacy project as the research site,…

Researchers have argued for an orientation to language as a resource that values bilingualism in mathematics classrooms. However, little is known about what mathematics teachers can do to translate a language-as-resource orientation into productive classroom practice. In this study, I analyze video data from two language immersion classrooms to…

Teachers in mathematics classrooms where the language of instruction differs from students' first language face competing demands regarding mathematics and language teaching. In this study, I conducted an analysis of genre of teaching episodes to examine how a teacher in a Spanish immersion third-grade classroom in the US responded to those…

As many K-6 students enrolled in dual language and bilingual programs enter middle and subsequently high schools that implement similar programs, content area teachers in Spanish face a twofold challenge: to remain aligned with the classroom discourse utilized in Spanish Language Arts (SLAs) and to implement effective strategies while teaching…

Translanguaging practices come into play in social interactions between bilinguals when they are making use of all their shared linguistic resources and blending their languages in natural ways. Stemming from these practices is translanguaging pedagogy, which is designed so that students in school-based additive bilingual programs can benefit from…

Immersion programs face a variety of challenges that are common to the field, such as lack of materials appropriate for students' language abilities, assessment, teacher recruitment and retention, balancing content and language, and relevant, high quality professional development for teachers. However, within specific micro-contexts, other issues…
