Language immersion programs seek to develop multilingual, multiliterate individuals able to engage with academic content. Studies of immersion students' language development provide details regarding language proficiency and accuracy, yet they generally do not address how features of written, academic language, for example, syntactic and lexical…

Indigenous-language immersion (ILI) is a form of schooling where all, or nearly all, classroom instruction in every subject area is conducted in an Indigenous language. This dissertation comprises three case study comparisons of neighboring pairs of ILI and English-medium school programs. The first case study examines two elementary schools in the…

French immersion (FI) programs are becoming increasingly culturally and linguistically diverse as a result of growing migration to Canada. In the present mixed-methods study, I explore the perspectives and ideologies of teachers, principals, and central office staff in eight school divisions in Saskatchewan, Manitoba, and Alberta with respect to…

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…

This brief explores the potential of bilingual programs to support access to core content courses for students classified as English Learners (ELs). The most common types of bilingual education programs in Oregon are: (1) dual language: instruction is in English and a partner language, with goals of biliteracy and bilingualism. This is also known…

Although there is an increasing number of middle schools establishing English immersion programs, teachers are not well-understood immersion and its application, as educators would hope them to do. Inadequate attention is paid to how teachers teach, how in-service training influences their understanding, and their practice of teaching. There is a…

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…

Considerable research on the two-way Spanish immersion model of education highlights benefits such as biliteracy, high academic achievement in both languages of instruction, and sociocultural competence for students of various linguistic and sociocultural backgrounds. The desire to gain these 21st century skills has caused a proliferation of dual…

This study examined (a) the identification of various reading groups across languages in Chinese (L1) adolescents learning English as a second language (ESL), in terms of their word-reading and reading comprehension skills, (b) overlap in reading group membership across languages, and (c) the performance of the various reading groups on…

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…

However influential the interdependence hypothesis has become in bilingual research, it still lacks full empirical support. This longitudinal study explores the parallels in the biliteracy development (L1 Spanish and L2 English) of 20 students in a European immersion programme (i.e. CLIL) over a two-year period. A bilingual learner corpus of…

Providing instruction in multiple languages has the potential to simultaneously help both native English speakers and English learners to develop language proficiency. "Dual language programs" can help native English speakers develop proficiency in a second language and English learners develop proficiency in both their native language…

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…

French second language education, including the option of one-way French immersion, is mandated for majority-language Anglophone children in New Brunswick, Canada's only officially bilingual province. Language ideological debates in the province surrounding official English--French bilingualism led us to investigate adolescent majority-language…
