Bilingual education has steadily risen in the United States since the Supreme Court case of "Lau vs. Nichols in 1974." Despite this proliferation of bilingual programs, notable challenges and discrepancies exist for bilingual programs devoted to Asian languages and Asian American and Pacific Islander (AAPI) communities. The rising…

In virtually every research paper on this topic we come across we read that, in the particular context that the writer is operating, English as a medium of instruction (EMI) is on the increase. But what exactly is EMI? If we consider every classroom around the world in which learners are exposed to English language as their second language (L2) we…

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 aims to understand the opinions of middle school and high school students about language learning and studying other content in an additional language in the school settings where English is used as the medium of instruction to teach more than 50% of the curriculum. For this end, 261 students from three different schools were…

This article starts with definitions of bilingualism with a focus on the analysis of bilingual competence. Then the aims and types of bilingual education in developing bilingual competence are introduced with focus on analyses of immersion and content-based instruction. Subsequently, the contextual settings of the study are briefly presented.…

This article starts with a review of definitions of bilingualism. It then discusses the definition of bilingual education with its focus on the analysis of bilingual competence. It is subsequently suggested that a theoretical hard nut to be cracked in today's bilingual research is to establish the scope of discussion of bilingualism models meeting…

Research on form focused instruction has provided support for the use of collaborative tasks in which learners focus their attention on formal aspects of language and consciously reflect on their own language use (i.e. produce language-related episodes or LREs). A strand of research on LREs in different educational contexts examines the effect of…

This article recounts three studies that portray an evolution from research examining the effects of researcher-designed instructional interventions to research examining the impact of helping teachers to design their own instructional interventions. Study 1 investigated the effects of an instructional treatment designed by the research team on…

We describe research results and lessons learned from a laboratory/ classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

This paper first considers what it means to become truly proficient in a language other than the native one. It then looks briefly at the evolution of dual language programs. Next, it focuses on the issue of whether the first language (L1) or the second language (L2) serves as the language of mediation. Other dual language program issues are then…

Immersion education, a variant of content-based instruction, is characterised by the dual curriculum goals of content and language learning. The content and language learning goals become increasingly complex and challenging at the late immersion level. One way to help students achieve these goals is by planning content and language learning…

This article looks at the characteristics of Content-Based Instruction (CBI) and Content and Language Integrated Learning (CLIL) in order to examine their similarities and differences. The analysis shows that CBI/CLIL programmes share the same essential properties and are not pedagogically different from each other. In fact, the use of an L2 as…

Two-way immersion (TWI) programs in the US are not reaching their minority language learning potential. While English home language (EHL) students develop functional proficiency, their minority language (e.g., Spanish) remains grammatically inaccurate. Spanish home language (SHL) students may also develop non-native-like aspects. Scholars suggest…

This study reports on an innovative approach to dual-language instruction (DLI) at the secondary-education level and introduces the 2-1-L2 model. The context of the study is an American Government class at a public charter high school in Tucson, Arizona, where the 2-1-L2 model was used for nine weeks to structure daily 90-minute lessons into a…

This paper explores how students in an Educational Psychology subject in a university L2 immersion context accomplish learning, mobilise their plurilingual repertoires and restructure their participation in carrying out a teamwork task over the course of approximately one week. The study is novel in several ways. First, it aims to fill a gap in…
