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…

This study reviews the emerging studies on the topic of Chinese immersion programs in the U.S. The effectiveness of Chinese immersion programs has been proved to have positive impacts on students' language proficiency, academic performance, and cognitive development. However, challenges in curriculum and instructions, behavior management, and…

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…

Purpose: This study examined the frequency of code-switching by Spanish-English-speaking children as a function of language proficiency in each language and diagnosis (developmental language disorder [DLD] or typical language development [TLD]). Method: Sixty-two Spanish-English-speaking children, 5-7 years of age, participated in this study (24…

Purpose: This longitudinal study investigated the trajectory of Spanish article accuracy in Spanish-English dual language learners (DLLs) from preschool to first grade, addressing the need for longitudinal data on the variability of Spanish grammatical skills in DLLs in English immersion classrooms. Method: Language sample analysis was conducted…

This dissertation focused on comparing the academic achievement and language proficiency in both English and Spanish of students at risk for language and learning difficulties, with bilingual typically developing students in two bilingual educational contexts: English as a Second Language program and Spanish two-way immersion program. Data was…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. The topics for this report on ELs and instructional programs include: (1) Number of States Reporting Bilingual Language Instruction Educational programs: SY 2015-16; (2) Number of States Reporting…

Many language learners lack the motivation to read complex texts. Because high-immersion Virtual Reality (VR) is increasingly reported to be highly motivating, the goal of our study was to compare English as a Second Language (ESL) learners' (N=79) motivation while reading a story with subtitles in VR (experimental group) versus reading the same…

Multilingualism is often associated with advantages for acquiring additional languages. Theoretical approaches explain these advantages by assuming a Common Underlying Proficiency or a Metalinguistic Awareness. At the State Europe School in Berlin, students from different language backgrounds receive instruction in German and a partner language…

Success in mathematics contributes to children's future career and lifelong financial security. There have been reports that dual-language education conveys academic advantages in mathematics achievement, although there is debate. This study aimed to investigate whether dual-language education benefits children's mathematics achievement and…

Chinese as the medium of instruction (MOI) is used across the curriculum for early childhood education in Hong Kong; however, kindergartens with non-Chinese speaking (NCS) students adopt different MOI, in which English remains an integral part of learning and teaching, to cater to the needs of NCS students and their families. The present study…

Guided by Dynamic Systems Theory (DST) and multidimensional perspectives on individual differences (IDs) in instructed second language (L2) learning (e.g., Larsen-Freeman, 2014; Sun & Zhang, 2020), this longitudinal mixed-methods study focuses on three conceptually different categories of L2 learners' IDs: working memory (WM), motivation, and…
