The "Filière Bilingue" (FiBi) is a Swiss public two-way immersion program integrating French-speaking, German-speaking and allophone learners (having neither French nor German as an L1) in each class. Located in the bilingual city of Biel/ Bienne, the "diglossic" situation represented by the use of Swiss German and standard…

This exploratory study evaluated the impact of a Spanish second language (L2) domestic immersion (DI) program that was developed expediently at a large university in the United States in response to widespread study abroad (SA) program closures due to COVID-19. Spanish language learners (n = 14) participated in an intensive, six-week summer…

Canadian students enrolled in either French-immersion or English-instruction programs were followed from Grades 2 to 3 (M[subscript age] = 7.8 years to 8.9 years; N = 244; 55% girls). In each grade, students completed two mathematical tasks that required oral language processing (i.e., word-problem solving and number transcoding from dictation)…

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…

This study examined seven Louisiana kindergarten immersion teachers' practices to evaluate students' oral target language production and compare the oral production elicited when different instructional practices were used over a single semester. Three rounds of three 20-minute observations in three different contexts--circle time, direct…

With 24 adolescent students enrolled in a French language summer camp, the present study examines the relationship between self-assessment and oral production in French, interpreting results through a framework of individual learning variables. Participants were surrounded by French inside and outside the classroom. Self-assessment was measured…

The assessment of dual language immersion (DLI) students' proficiency in the partner language plays a key role in program evaluation. This article reports findings from a large-scale study, drawing on cross-sectional assessment data from 73 schools and longitudinal data from 25 schools. Students were tested in the interpretive (listening and…

The aim of this paper is to analyse some aspects of development of Basque as a second language (L2) in children for whom Spanish is their first language (L1) who attended immersion school in Basque in a Spanish-speaking sociolinguistic context. Data consist of oral story retellings produced in a classroom setting where the same children…

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.…

In this study, we examined the bilingual language development among Korean American first-graders in two southern California cities and explored the opportunities for language use available to them in various spaces: at school (one dual language immersion school and one traditional English-only public school), at home, and in the community. Data…

The classroom demographics in French immersion (FI) programs across Canada are changing: There are a growing number of multilingual students who are learning English as a second language (L2) and French as a third language (L3). However, little is known about the development of French language proficiency and reading skills of multilingual…

This study investigated the effect of mother tongue instruction and gender on second language acquisition using a causal-comparative quantitative research design. The two distinguishing groups compared were (i) learners that were taught in their mother tongue (Afrikaans) and (ii) learners that were not taught in their mother tongue but in English,…

Recent literature in second language (L2) perceived fluency has focused on English as a second language, with a primary reliance on impressions from native-speaker judges, leaving learners' self-perceptions of speech production unexplored. This study investigates the relationship between learners' and judges' perceptions of French fluency under…

Research has demonstrated that students in dual-language immersion programs perform as well as, or better than, their peers in core academic content areas by late elementary school. However, the extent to which immersion education fosters bilingualism has received less attention in the literature. Using data from a four-year efficacy study of…
