Gifted students often display advanced verbal abilities that facilitate second language acquisition; however, when instruction is insufficiently stimulating, they may experience boredom and demotivation. Due to rising interest in immersive technologies such as augmented reality (AR) and limited evidence of their impact on gifted language learners, a systematic scoping review was necessary to synthesise existing research and identify gaps. It examined the impact of AR on both linguistic development and motivational outcomes among gifted learners in ESL/EFL contexts. It was preregistered in the Open Science Framework (OSF) and conducted according to PRISMA-ScR guidelines. Eligible studies included gifted learners in ESL/EFL contexts, published between 2020 and 2025 in English, Spanish, French, or Italian. Exclusion criteria comprised non–peer-reviewed papers and studies unrelated to AR. Searches were conducted in Scopus, Web of Science, ERIC, and Redalyc. A total of 34 studies were included. Findings indicate that AR interventions improve vocabulary, listening, pronunciation, and fluency; writing also benefits, although grammar remains challenging. AR enhances intrinsic motivation, reduces anxiety, and fosters engagement, especially in younger learners. The results suggest that AR can be a valuable tool in EFL/ESL classrooms to support both linguistic development and motivation among gifted students, though sustainable implementation requires overcoming technological and pedagogical barriers.

Research has shown that language ability can vary enormously depending on variables such as musical ability, musical training, and second and/or foreign language experience. In this study, we simulated initial foreign language learning conditions in which learners must recognize and match unfamiliar language input. We recruited 500 participants with different levels of foreign language experience, different levels of musical training and different socio-economic backgrounds. Their auditory phonological pattern recognition ability, short-term memory (STM) capacity, musical ability, musical self-estimation, educational status, and socio-economic status (SES) were assessed. Both overall and group-specific analyses were conducted to investigate the impact of these variables. For the group-specific analysis, participants were assigned to four groups based on the presence or absence of musical training and extensive foreign language experience. For the overall analysis, regression models were applied to the entire sample to examine the combined effects of all variables. Group-specific analyses revealed that both musical training and extensive foreign language experience contributed to individual differences in the ability to recognize phonological patterns in unintelligible auditory stimuli. A key finding was that musical training appeared to have a stronger influence on auditory phonological pattern recognition than extensive foreign language experience, particularly in the early stages of language learning. This suggests that musical training may exert a greater impact on initial phonetic acquisition processes than extensive foreign language proficiency, especially when the language stimuli are relatively poor in linguistic content. The overall analysis revealed that musical variables, short-term memory capacity, socioeconomic status, and educational status all contributed to individual differences in auditory phonological pattern recognition. Notably, the most significant finding of the overall analysis was the association between SES and auditory phonological pattern recognition in unfamiliar speech—a result that challenges the notion of aptitude measures as stable and environment-independent and highlights the potential influence of environmental factors on this capacity.

As has repeatedly been pointed out in recent years, the categories ESL/Outer Circle and EFL/Expanding Circle should not be considered as clear-cut as traditionally assumed. Consequently, recent research has made first attempts for an integrative approach to Englishes traditionally ascribed to one of these categories. The paper at hand introduces the Extra- and Intra-territorial Forces Model (EIF Model) as a successful attempt to bridge the traditional gap between the two categories and shows how the model works in practice by implementation to the cases of Greece and Cyprus. These two countries are particularly interesting for the application of this framework since their linguistic ecologies, with Greek and English in contact, are essentially similar. From a historical perspective, however, they are fundamentally different; Cyprus is a former colony of the British Empire, whereas Greece has never experienced British colonization. Therefore, the two countries offer the perfect basis for putting the traditional categories of EFL and ESL to the test and for illustrating how more recent models of World Englishes, such as the EIF Model, might offer more flexible theoretical alternatives to earlier, often more rigid theoretical approaches.

This study investigates how short-term naturalistic immersion shapes the development of evaluative narrative competence in Japanese junior high school students learning English as a foreign language. While prior second language acquisition (SLA) research has established the benefits of input-rich environments, little is known about how implicit learning during brief immersion experiences supports higher-order storytelling skills. To address this gap, we analyzed students’ performance on a standardized problem-solving task and a storytelling task before and after a one-month homestay abroad. Results showed significant post-immersion gains in narrative complexity, with longer stories, greater use of causal and evaluative devices, and increased diversity of expression. Regression analysis revealed that the age of first English exposure strongly predicted outcomes: early starters demonstrated broader and more sophisticated use of evaluative strategies than later starters. These findings suggest that short-term immersion can substantially enhance narrative competence, particularly for learners with early exposure, while highlighting the need for tailored pedagogical interventions to help later starters capitalize on implicit learning opportunities.

This longitudinal study examines the acquisition of target-like patterns of phonological variation by 17 second language (L2) French learners during a semester or year of study abroad (SA) in France. In this study, speech data from sociolinguistic interviews conducted before, during, and after the SA period provide evidence for the emergent acquisition of a phonological variable showing sociostylistic variation in first language (L1) speech: the reduction of word-final obstruent-liquid clusters, as in: notre maison [no tʁ(ə) mɛ ʒɔ̃] ~ [not mɛ ʒɔ̃] ‘our house’; c’est incroyable [se tɛ̃ kʁɔ ja bl(ə)] ~ [se tɛ̃ kʁɔ jab] ‘it’s incredible’. Additionally, speech data are compared and correlated with the results of a social network strength scale designed by the researcher for the SA learning context. Results suggest that sociostylistic variation patterns among learners are constrained by linguistic factors similar to those operating on L1 speech, such as lexical effects, and that time in the target language (TL) environment is a significant predictor of variation. Results also demonstrate that although social network strength is not a significant predictor of variation at a group level, speaker gender is, and learner patterns reflect the gendered speech norms of the TL community.

In an increasingly globalized world, learning foreign languages (FLs) is essential, particularly in education. Multilingualism is critical due to the multicultural and interconnected nature of societies, yet early third language acquisition (TLA) is not widely adopted in schools. This study investigates how the simultaneous learning of Spanish first language (L1), a second language (L2), and a third language (L3) impacts oral language (OL) development in L1 and whether prior L2 knowledge aids L3 acquisition. The study involved bilingual (L1 + L2) and trilingual (L1 + L2 + L3) learners. Data were collected using the Navarre Oral Language Test-Revised, which evaluates phonological, morphological–syntactic, lexical–semantic, and pragmatic competencies in oral communication. Findings revealed that trilingual learners showed better OL development in L1 compared to bilingual learners. Additionally, prior L2 knowledge facilitated L3 learning, highlighting the benefits of early trilingual education. The study demonstrates that early trilingual learning positively impacts OL development in L1. These results contribute significantly to research on TLA and the advancement of multilingual education.

The global expansion of Korean language education has created an urgent need for scalable, objective, and consistent methods for assessing the writing skills of non-native (L2) learners. Traditional manual grading is resource-intensive and prone to subjectivity, while existing Automated Essay Scoring (AES) systems often struggle with the linguistic nuances of Korean and the specific error patterns of L2 writers. This paper introduces a novel hybrid AES system designed specifically for Korean L2 writing. The system integrates two complementary feature sets: (1) a comprehensive suite of conventional linguistic features capturing lexical diversity, syntactic complexity, and readability to assess writing form and (2) a novel semantic relevance feature that evaluates writing content. This semantic feature is derived by calculating the cosine similarity between a student’s essay and an ideal, high-proficiency reference answer generated by a Large Language Model (LLM). Various machine learning models are trained on the Korean Language Learner Corpus from the National Institute of the Korean Language to predict a holistic score on the 6-level Test of Proficiency in Korean (TOPIK) scale. The proposed hybrid system demonstrates superior performance compared to baseline models that rely on either linguistic or semantic features alone. The integration of the LLM-based semantic feature provides a significant improvement in scoring accuracy, more closely aligning the automated assessment with human expert judgments. By systematically combining measures of linguistic form and semantic content, this hybrid approach provides a more holistic and accurate assessment of Korean L2 writing proficiency. The system represents a practical and effective tool for supporting large-scale language education and assessment, aligning with the need for advanced AI-driven educational technology systems.

This study is about Palestinian university students’ attitudes toward English as a foreign language (EFL) learning, paying special attention to variables such as gender, parents’ knowledge of a foreign language, academic year, and travel to English-speaking countries. The researchers implemented a descriptive–analytical design to collect data. The sample of the study is 570 university students across various higher education institutions in Palestine. The researchers used several statistical tests, such as an Independent Sample t-test and one-way ANOVA, to analyse data. The findings suggest that Palestinian university students’ attitudes toward learning English are mainly neutral. However, there are positive inclinations in specific aspects such as travel, academic content, and reading and writing, with no statistically significant differences due to variables such as gender, academic year, or exposure to English-speaking countries. These results suggest that student attitudes are shaped less by personal background and more by broader sociopolitical and educational conditions. This study contributes to the limited body of localised research on affective variables in second language acquisition (SLA) within conflict-affected regions. It highlights the need for contextually responsive pedagogies that promote student engagement and linguistic resilience. Implications are offered for educators, curriculum developers, and policymakers seeking to enhance EFL instruction in Palestine and similar settings. Full article

Metaphorical competence—the capacity to comprehend and produce metaphors in a second language (L2)—is essential for nuanced, accurate, and contextually appropriate English usage. Synthesizing 40 independent studies (N = 15,786), this meta-analysis quantified the relative contributions of cognitive, linguistic, and personal factors to L2 metaphorical competence. Effect sizes were derived from correlation coefficients and aggregated under random-effects models to account for between-study heterogeneity. Linguistic factors emerged as the dominant predictor (r = 0.421, 95% CI [0.34, 0.50]), primarily driven by vocabulary breadth/depth and reading proficiency. Cognitive factors exerted a moderate influence (r = 0.232, 95% CI [0.17, 0.30]), whereas personal variables such as gender yielded only a small effect (r = 0.216, 95% CI [0.15, 0.28]). Moderator analyses further revealed that L1 conceptual knowledge constitutes the strongest single predictor of L2 metaphor skills and highlighted distinct associations between receptive and productive metaphor abilities with linguistic versus cognitive aptitudes. The findings collectively point to lexico-semantic and literacy development as the main levers for boosting L2 metaphorical competence, with cognitive aptitudes and personal factors acting as secondary, yet important, modulators. Insight from this meta-analysis offers a robust foundation for evidence-based decisions in curriculum design, materials selection, and targeted pedagogical interventions. Full article

We argue that quantitative analysis of community-based speech data furnishes an indispensable adjunct to theoretical and experimental studies targeting the acquisition of relativization. Drawing on a comparative sociolinguistic approach, we make use of three corpora of natural speech to investigate second-language (L2) speakers’ acquisition of restrictive relative clauses in English. These corpora comprise: (i) spontaneous L2 speech; (ii) a local baseline variety of the target language (TL); and (iii) L2 speakers’ first language (L1), French. These complementary datasets enable us to explore the extent to which L2 speakers reproduce the discursive frequency of relative markers, as well as their fine-grained linguistic conditioning, in the local TL baseline variety. Comparisons with French facilitate exploration of possible L1 transfer effects on L2 speakers’ production of English restrictive relative clauses. Results indicate that evidence of L1 transfer effects on L2 speakers’ restrictive relative clauses is tenuous. A pivotal finding is that L2 speakers, in the aggregate, closely approximate TL constraints on relative marker selection, although they use the subject relativizer who significantly less often than their TL counterparts. We implicate affiliation with, and integration into, the local TL community as key factors facilitating the propagation of TL vernacular norms to L2 speakers. Full article

Late bilingual speakers immersed in a second language (L2) environment often experience the non-pathological attrition of their first language (L1), exhibiting selective and reversible changes in L1 processing and production. While attrition research has largely focused on long-term residents in anglophone countries, examining changes primarily within a single L1 domain, the present study employs a novel experimental design to investigate L1 attrition, alongside L2 acquisition, across three domains (i.e., the lexicon, syntax–pragmatics interface, and prosody) in two groups of L1-English L2-Italian late bilinguals: long-term residents in Italy vs. university students in the UK. A total of 112 participants completed online tasks assessing lexical retrieval, anaphora resolution, and sentence stress patterns in both languages. First, both bilingual groups showed comparable levels of semantic interference in lexical retrieval. Second, at the syntax–pragmatics interface, only residents in Italy showed signs of L1 attrition in real-time processing of anaphora, while resolution preferences were similar between groups; in the L2, both bilingual groups demonstrated target-like preferences, despite some slowdown in processing. Third, while both groups showed some evidence of target-like L2 prosody, with residents in Italy matching L1-Italian sentence stress patterns closely, prosodic attrition was only reported for residents in Italy in exploratory analyses. Overall, this study supports the notion of L1 attrition as a natural consequence of bilingualism—one that is domain- and experience-dependent, unfolds along a continuum, and involves a complex (and possibly inverse) relationship between L1 and L2 performance that warrants further investigation.

The study investigates the interplay among second language (L2) learners’ willingness to communicate (WTC), L2 self-confidence (L2SC), and academic self-concept (ASC) within a cohort of Vietnamese university students studying in the United Kingdom. Employing an explanatory sequential mixed-methods design, self-reported quantitative data were collected via validated survey instruments (n = 32 students), followed by semi-structured interviews with a purposive subsample (n = 5 students) to contextualise the findings. Results revealed that participants exhibited moderate levels of WTC and L2 self-confidence, alongside emerging academic self-concept. Significant positive correlations were observed between WTC and L2 self-confidence and between L2 self-confidence and academic self-concept; a weak, non-significant association was found between WTC and academic self-concept. Qualitative data corroborated these patterns, highlighting how learners’ communicative confidence was shaped by supportive environments and evolving self-perceptions. While self-comparisons and cultural expectations occasionally influenced students’ academic self-concept, most participants reported resilience and a commitment to communication development. The study contributes to the literature by integrating psychological and contextual variables influencing WTC, offering pedagogical implications for enhancing communicative competence among international English as a second language learners.

English phrasal verbs are ubiquitous and challenging for second language (L2) learners, particularly for those whose first language does not have an equivalent structure. This study investigates the facilitative role of three distinct L2 practice types in promoting English phrasal verb acquisition. Eighty first-year college students from China were randomly assigned to three groups: the continuation group, which was first presented with an input text and then required to complete it; the retrieval group, which was first presented with the input text and then required to engage in retrieval practice; and the trial-and-error group, which was first required to engage in trial-and-error practice before reading the input text. The effectiveness of these practice types was compared via both an immediate post-test and a 1-week-delayed post-test. The results showed that in the immediate post-test, the continuation group performed comparably with the retrieval group but outperformed the trial-and-error group. However, in the 1-week-delayed post-test, the continuation group significantly outperformed the other two groups. The findings revealed that the continuation writing task not only initially equips learners with declarative knowledge and subsequently closely integrates static L2 learning with dynamic idea expression but also enhances learners’ task self-efficacy, thereby optimally promoting phrasal verb learning and retention.

This study investigates the impact of structured input, referential activities, and affective activities on English simple past tense acquisition in a second language (L2). Thirty-three participants from a senior high school were divided into four groups based on the pretest–posttest design: referential only, affective only, a combination of both, and a control group. A self-paced reading (SPR) test was used to measure accuracy and response times to evaluate the effectiveness of these instructional strategies. Structured input and referential tasks enhance grammatical acquisition more rapidly and accurately than affective-only treatments or controls, showing the beneficial effects of structured input on grammar acquisition. The results emphasized the importance of designing instructional strategies that address specific processing challenges in L2 learning by focusing on form–meaning connections. By demonstrating differential impacts of structured input activities on grammatical learning and processing efficiency, the research contributes to the field of second language acquisition. The SPR method was selected for its ability to capture subtle, immediate differences in processing at the word level, its suitability for controlled classroom-based online administration, and its established validity in L2 processing research. Unlike other methods, SPR allows precise measurement of reaction times for specific sentence components, isolating processing effects of the target grammatical form while minimizing the influence of explicit knowledge.

Technological advances have enabled the development of innovative educational tools, particularly those aimed at supporting English as a Second Language (ESL) learning, with a specific focus on oral skills. However, pronunciation remains a significant challenge due to the limited availability of personalized learning opportunities that offer immediate feedback and contextualized practice. In this context, the present research proposes the design, implementation, and validation of an immersive application that leverages virtual reality (VR) and artificial intelligence (AI) to enhance English pronunciation. The proposed system integrates a 3D interactive environment developed in Unity, voice classification models trained using Teachable Machine, and real-time communication with Firebase, allowing users to practice and assess their pronunciation in a simulated library-like virtual setting. Through its integrated AI module, the application can analyze the pronunciation of each word in real time, detecting correct and incorrect utterances, and then providing immediate feedback to help users identify and correct their mistakes. The virtual environment was designed to be a welcoming and user-friendly, promoting active engagement with the learning process. The application’s distributed architecture enables automated feedback generation via data flow between the cloud-based AI, the database, and the visualization interface. Results demonstrate that using 400 samples per class and a confidence threshold of 99.99% for training the AI model effectively eliminated false positives, significantly increasing system accuracy and providing users with more reliable feedback. This directly contributes to enhanced learner autonomy and improved ESL acquisition outcomes. Furthermore, user surveys conducted to understand their perceptions of the application’s usefulness as a support tool for English learning yielded an average acceptance rate of 93%. This reflects the acceptance of these immersive technologies in educational contexts, as the combination of these technologies offers a realistic and user-friendly simulation environment, in addition to detailed word analysis, facilitating self-assessment and independent learning among students.
