Although research on content and language integrated learning (CLIL) has shown that CLIL instruction may enhance students' second or foreign language learning compared to regular foreign language instruction, there are also studies that have indicated similar language development between CLIL and non-CLIL students. However, CLIL can be organized…

This book gives an overview of the linguistic development of Korean-English bilingual children living in the US. It provides a detailed longitudinal account of English and Korean acquisition in early childhood, offering a close examination of Korean-American children's code-switching and morphology and syntax development during a time when their…

This study builds upon previous research investigating the construct validity of phraseological complexity as an index of L2 development and proficiency. Whereas previous studies have focused on cross-sectional comparisons of written productions across proficiency levels, the current study compares the "longitudinal" development of…

Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

The effects of Content and Language Integrated Learning (CLIL) on students' foreign language skill development have been overestimated by previous studies, as most studies needed to have considered selection and preparation effects appropriately. We used complete survey data from a 1996-2003 cohort to investigate English skill development of N =…

Purpose: This study aimed to examine changes in English and Spanish morphosyntactic standardized scores over time in bilingual children. Method: One hundred bilingual children participated in this longitudinal study. The average age of the children at the beginning of the study was 5;11 (years; months). A subset of the participants was identified…

Whilst the links between learner corpus research (LCR) and Second Language Acquisition (SLA) have long been debated, McEnery et al. (2019. "Corpus Linguistics, Learner Corpora, and SLA: Employing Technology to Analyze Language Use." Annual Review of Applied Linguistics 39: 74-92. doi:10.1017/S0267190519000096) claim that learner corpus…

This study explores the experiences of second-generation Latine adolescents by examining the impact of bilingualism on self-esteem and depressive symptoms. Drawing on Suarez-Orozco and colleagues' (2018) model, this study shows the multifaceted acculturation process, emphasizing linguistic acculturation as crucial for navigating two cultures. The…

This study investigated lexical complexity in English language teaching (ELT) students' essays across genres and over the course of time. The essays included descriptive, compare and contrast, advantage and disadvantage, and argumentative genres. Employing a longitudinal, quasi-experimental and repeated measures design in a year-long writing…

The current study examined cognitive effects of two pathways of second language (L2) acquisition longitudinally in Chinese speakers learning English in an L2-dominant environment. Thirty-nine participants who attended an intensive 10-week English course (L2-instruction group) were compared to 38 participants who attended regular university courses…

This paper reports on a writing programme I started at Bronx Community College to improve academic success among recently immigrated Spanish-speaking students by linking ESL courses to Spanish academic literacy courses within the framework of a learning community. My reflection begins by articulating the pedagogical rationale for looking beyond…

Research on assessing English as a foreign language (EFL) development has been growing recently. However, empirical evidence from longitudinal analyses based on substantial samples is still needed. In such settings, tests for measuring language development must meet high standards of test quality such as validity, reliability, and objectivity, as…

This study analyzes the influence of English medium instruction (EMI) on student English writing development in a Spanish undergraduate context, a language skill that remains underexplored in EMI research at tertiary level. Through a longitudinal pre- and post-test method, it explores the writing progress of EMI engineering students as compared to…

This longitudinal mixed-methods case study aimed to explain why a seemingly ordinary U.S.-affiliated hyper-connected French language learner (Nancy) achieved extraordinary outcomes after 15 weeks in Paris, compared to fifteen Generation Z peers also enrolled in the program. Framed by Complex Dynamic Systems Theory and social pedagogies, the study…

This study assessed the influence of a 10-week teacher emotionally supportive quasi-experimental intervention on the perceived teacher emotional support (PTES), basic psychological needs (BPNs) satisfaction, emotions of anxiety and enjoyment, and emotional engagement of learners of English as a foreign language (EFL). Strategies targeting the…
