The present study investigated the relation between continuous measures of two qualitatively different types of bilingual experience and outcome measures that varied in domain (verbal or nonverbal) and processing demands (degree of conflict). Participants were 195 English-speaking children, 7 years old, who were enrolled in French immersion…

The first goal of this study was to examine how individual differences in initial L2 proficiency help explain L2 grammar development in oral production during short-term immersion abroad. The second goal of the study was methodological, and evaluated challenges that can result from operationalizing learners' initial L2 proficiency as pretest…

Research demonstrates that content, language, and literacy integration is challenging for teachers working in content-based instructional contexts such as immersion and Content and Language Integrated Learning. Although teacher preparation programs for content-based instruction contexts exist, it is unclear whether and how they help…

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…

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…

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…

This study explores the relationship of early immersion education, socioeconomic background, and cognitive gains of young learners. We examine the possible advantages of early bilingual education and the impact of family socioeconomic status (SES) for the cognitive development of children. Participants (N = 39) were students at regular (German) or…

This study investigates the enhancement of spoken English proficiency among students at Taiwan's technological and vocational education (TVE) universities. The focus is on the significant impact of positive learning attitudes and effective methodologies, using questionnaires and in-depth interviews to assess students' confidence and perceptions of…

Though Mandarin Chinese dual language immersion (DLI) has been growing rapidly in the U.S., research on this population is still rare. This study explored cross-language transfer of expressive oral vocabulary knowledge and definition skills among students in a Chinese DLI program. We found significant within and cross-language relationships of…

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…

The strengths and limitations of English as a Medium of Instruction (EMI) have been extensively studied in the field of English language teaching. However, limited attention has been given to the aspirations of non-elite middle-class parents in Bangladesh, who strongly value EMI for its perceived instrumental benefits, thereby creating a…

Language learning has long been one of the most challenging issues facing non-Chinese speaking (NCS) students who are mainly ethnic minorities immersed in a multilingual environment in Hong Kong. Previous research on the education of NCS students suggested that early support from an immersion programme at a pre-school age may contribute to higher…

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

The number of English learners (ELs) who do not reclassify as English proficient after the first five years of schooling has increased across the state of Texas. ELs are a diverse population of students with varying levels of English proficiency. Many students who begin school as an EL reclassify as English proficient in a timely manner and go on…

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…
