Chinese immersion programs have been increasingly popular in US schools. However, we have insufficient data on young English-speaking children's acquisition of Chinese as a second language in these programs, and specifically on social contextual variables systematically promoting or hindering Chinese language use. Taking a variationist…

Dual language immersion (DLI) as an alternative model to monolingual English-medium education has continued to expand rapidly over the past decade. As this model continues to grow across the United States, stakeholders look to research to demonstrate sustainability and scalability of dual language programs. Drawing on 224 schools, the statewide…

Evidence suggests that short-term study abroad experiences can help advance various dimensions of second language (L2) learners' linguistic competence. However, the extent to which gains following a brief sojourn are durable and maintained after immersion remains an open question. The present study examined both the immediate and sustained…

Ecological approaches to language learning and materials use represent educational settings as complex and dynamic systems by applying relational perspectives from the natural world in the classroom. For young bilingual Ojibwe learners, the natural world (i.e., local, rural, and reservation land) is a significant language learning resource unto…

This study examines first language (L1) English transfer in the acquisition of plural noun semantics in second language (L2) Arabic. Drawing on previous research on the L2 acquisition of plural noun interpretation, the study presents and discusses new production data of specific and generic definite plurals by English-speaking learners of Arabic…

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…

This study reveals hitherto overlooked effects of age of onset (AO) in immersive school contexts, using multiple measures over time so as to focus on fluctuations and trends in individual data. The second language (L2) English development was studied in 91 children who received 50-50 content and language integrated learning (CLIL) instruction in…

While there exists a considerable body of literature on task-based difficulty and second language (L2) fluency in English as a second language (ESL), there has been little investigation with French learners. This mixed methods study examines learner appraisals of task difficulty and their relationship to automated utterance fluency measures in…

This cross-sectional study used assessments developed by the Center for Applied Linguistics to examine the oral proficiency of 218 K-8 English-proficient students in 4 Spanish immersion programs. Following a comprehensive review of assessment results for English-proficient immersion learners, the article reports findings from statistical analyses.…

The policy of strict separation of languages for academic instruction dominates dual language bilingual education programming. This article explores the dynamic bilingual practices of two experienced bilingual teachers in a two-way dual language public school in Texas and contributes to current research problematizing language separation. Data…

Research on immersion teaching has consistently shown that immersion teachers tend to focus on subject matter content at the expense of language teaching. The response to that research has often entailed suggestions for teachers on how better to integrate language and content in their instruction. However, missing from the discussion are rich…

This article reports analysis of data collected from a quasi-experimental study in 2 Canadian late French immersion science classes. We examine if, how, and when the first language (L1) is used when students in the first years of their second language learning talk about complex science concepts. We compare differences in groups following a…

This longitudinal study asks 2 questions. The first one is: What patterns of pragmatic development can we observe among different pragmatic functions and attributes in a second language (L2)? The second question is: In what ways do individual differences and learning context affect the course of pragmatic development? Forty-eight Japanese college…

The defining feature of immersion language learning is the omnipresent pressure to communicate in the second language (L2), even as incipient skills are being acquired. This study uses the focused essay technique to investigate ambivalence about communicating among adolescent French immersion students (12-14 years of age). Students described…

Using a sociocultural theoretical lens, this study examines the nature of student interactions in a dual immersion school to analyze affordances for bilingual language learning, language exchange, and co-construction of language expertise. This article focuses on data from audio- and video-recorded interactions of fifth-grade students engaged in…
