Task planning and its effect on the complexity of second language (L2) written production have been studied extensively. However, the results of these studies are inconclusive, and at times contradictory, potentially as a result of variation in metrics of linguistic complexity. This study is an extension of earlier research syntheses and quantitative meta-analyses on the effects of planning on oral and written L2 production. It examines the identification and selection of linguistic complexity metrics in previous research on planning and its subsequent effects on the linguistic complexity of written L2 production. This research-focused synthesis of studies surveys construct definitions and operational definitions of linguistic complexity in the research domain and provides an overview of rationales for metric selection in the included studies. Methodological implications for future research are discussed in light of the findings.

Although word lists have generated a great deal of attention from researchers, there has been no comprehensive review of the applications of word lists in second language learning and teaching. This article reviews the development, validation, and applications of 50 word list studies that were published and discussed in major international peer-reviewed Applied Linguistics and TESOL journals from 2013 to 2023. It shows that the methodology of word list development and validation has become more sophisticated and word list developers can see many potential applications of their lists in research and pedagogy. However, most applications of recently developed word lists have been restricted to the BNC/COCA lists developed by Paul Nation, and little is known about the degree to which most word lists have been used in pedagogical contexts. Our review indicates several directions for future research on word lists, including exploring the impact of published lists on pedagogy, replicating word list studies for learners in underrepresented contexts, and developing sustainable, low-cost methods of developing word lists to allow teachers and learners to create lists serving their own needs.

The past few years have witnessed an emergent growth of both academic and practical works on English medium instruction (EMI) teachers' professional development. This paper presents a critical analysis of 30 empirical studies on EMI teacher development in a wide range of higher educational settings from 2018 to 2022. Through a systematic process of paper selection and review, we have identified three general routes to EMI teacher development, namely: (1) formal training activities; (2) opportunities for teacher collaboration; and (3) self-initiated practices. For each route, we presented a critical appraisal of their design and implementation, as well as reported gains and challenges. Meanwhile, we also conducted a critical analysis of the methodological issues pertaining to the selected papers. Overall, we argue that EMI teacher development in higher education is largely construed as a hybrid, contested, and transformative enterprise featured by EMI teachers' constant boundary-crossing at different levels to seek professional growth in linguistic, pedagogical, cultural, and psychological domains. During this process, EMI teachers may encounter conflicted dispositions, power asymmetries, and individual contradictions. Such a process thus requires EMI teachers to rethink, reexamine, and reflect critically on their accustomed preconceptions and practices, in order to facilitate transformation and achieve sustainability in the long run. The review also presents implications for EMI teachers, teacher educators, policymakers, and researchers on effectively facilitating EMI teacher development in higher education.

This paper discusses the complexities of teaching Hebrew to Israel's largest minority group, the Arabs, who must be fluent in the language if they are to succeed. While policy-making institutions in Israel today are aware of the importance of Hebrew for Arab students, the teaching of Hebrew faces serious challenges involving the status of Hebrew in Arab society, the inner-Arab state of diglossia, and the training and placement of Arab teachers of Hebrew. The distribution of the Arab population (in mixed Jewish–Arab towns, and in Arab towns and villages), as well as differing levels of exposure to Hebrew, also pose considerable challenges. The paper combines a historical-theoretical with a philosophical-theoretical approach. It analyzes findings of previous studies that examined Hebrew writings of Arabs studying to be teachers of Hebrew, and policy documents dealing with teacher training and placement in the schools. Our study found a profound gap between Arab Hebrew teachers' academic-pedagogical training and its implementation. Our main recommendations for reducing the gap are: (1) the curriculum should take Israeli Arabs' sociolinguistic situation into account; (2) the teacher placement system needs an overhaul; and (3) the teaching of Hebrew should begin in third grade.

Investigating speech fluency has, for a long time, been at the core of second language (L2) studies, as fluency is believed to epitomise successful acquisition of L2, characterise effective communication, elucidate the complex process of acquisition, and predict L2 speakers' proficiency. The significance attributed to fluency in these areas explicates the research attention paid to it over the past decades. An important area of development in this regard is L2 assessment in which fluency is recognised as a key underlying construct of spoken language ability by international language tests (e.g., IELTS, TEEP, APTIS) and language benchmarks (e.g., CEFR). Many high-stakes tests of English and other languages include fluency in their rating scales, with the earliest on record tracing back to the 1930s – the College Board's English Competence Examination (1930) in America. Including fluency as a fundamental aspect of speaking ability in the rating scales, rating descriptors, and rater training materials, either as an independent criterion or combined with others (e.g., delivery), has become common practice in language testing over the past decades. What has made assessment of fluency even more appealing to researchers and test providers in recent years is the objectivity and reliability of its measurement and its compatibility with the technological developments in automated assessment of speaking. Fluency is now largely recognised as a construct that can be efficiently and reliably assessed in automated assessment of spoken language ability and used to predict proficiency (de Jong, 2018*; Ginther et al., 2010*; Kang & Johnson, 2021*; Tavakoli et al., 2023).

Decades before educators were forced to confront the disruption posed by widely accessible generative artificial intelligence (AI) tools such as ChatGPT, language learners, instructors, and researchers began dealing with its game-changing predecessor: machine translation (MT). Researchers began assessing MT systems and proposing language teaching applications for them as soon as universities and schools gained access to them in the mid-1980s (*Anderson, 1995*; Ball, 1989*; Corness, 1985; French 1991; Lewis, 1997; Richmond, 1994*). These inquiries accelerated in the early 2000s, when internet-enabled computer labs and increasingly smarter devices put free online MT services such as Babel Fish and Google Translate (GT) at students' fingertips, triggering concerns over output quality, academic dishonesty, and the short-circuiting of actual learning. In recent years, there has been a veritable explosion of research on MT's role in and impact on language teaching and learning, with many dozens of peer-reviewed articles published in the past five years alone, as documented in a handful of comprehensive literatures reviews (Gokgoz-Kurt, 2023; Jiang et al., 2024; Jolley & Maimone, 2022; Klimova et al., 2023; Lee, 2023). The present article provides a timeline of this rapidly expanding research domain.

During the past 20 years, the expansion of bilingual education programmes in Spain has generated a situation where the voices of stakeholders frequently go unheard. Accordingly, this paper is a critical review of bilingual programmes within the Spanish context. An analysis has been carried out on stakeholder perceptions, that is, of teachers, students, management teams, and families, as reflected in the literature published between 2014 and 2023. The corpus reviewed consists of 34 papers, ranging from pre-primary to higher education, with a particular focus on stakeholders' perceptions of the implementation of bilingual education in a foreign language (English). In terms of the characteristics of the studies analysed, the predominance of teachers' perceptions over other stakeholders and the scarcity of longitudinal studies and research based on national samples should be noted. The adoption of a more robust methodological design could provide a fuller assessment of the implementation of bilingual education in Spain. Nonetheless, this review highlights the need for specific improvements at each level of education if a more learner-centred approach to teaching is to be achieved. Such improvements could include additional training opportunities, collaboration among teachers, and measures to alleviate the additional workload associated with bilingual education.

In the past decade, there has been increasing scholarly interest in language teachers’ emotional experiences, how they regulate and manage their emotions, and how their experiences and emotion-related practices are related to their cognition, practice, well-being, and professional development. A systematic and critical review is needed to help language teaching professionals to benefit from the insights generated by these studies. This review aims to explore this growing body of research on the emotions of language teachers published between 2015 and 2024 by outlining four major research themes: 1) emotional experience; 2) emotion labour; 3) emotion regulation; and 4) emerging emotion-related concepts. This review critically discusses these themes and draws on relevant research findings to visualise the results in an emotion-focused map of language teachers’ professional development. It concludes by proposing a research agenda to stimulate further inquiry into the emotions of language teachers.

In our critical review, we explore the progress of second language (L2) teaching research in Japan from 2019 to 2023, focusing particularly on English Language Teaching (ELT) and Japanese Language Teaching (JLT). After scrutinising numerous publications from over 50 academic journals, as well as academic books and chapters, we selected around 40 studies for analysis. These studies met our screening criteria of articles published in Japan, which were written in English or Japanese, peer-reviewed, presented original findings or insights, and focused on the Japanese context. We highlighted six key areas: grammar, language testing, teachers’ professional development, the realities and influences of foreign residents and immigration, the identity of language learners/users and language education policy. Through our review, we provide notable characteristics, developments, and challenges in L2 teaching research in Japan for a global readership. This contribution furthers the ongoing conversation and sets directions for future research in this field.

Research into young learners' metalinguistic awareness has led to both definitions of the construct and key findings about its role in children's cognitive and linguistic development. I briefly summarise this research before introducing two established theoretical models that can help us understand the concept of metalinguistic awareness more broadly: Ellen Bialystok's classic dichotomy of analysis of knowledge and control of processing, and Rod Ellis's notion of explicit (second language) knowledge. This is followed by an overview of measures of metalinguistic awareness that have been used in empirical studies to date as well as an illustration and critique of selected measures. As a result, I propose a model that combines features of the two previous frameworks by conceptualising knowledge representations and processes in terms of (1) how implicit/explicit and (2) how specific/schematic they are. I explain this model to illustrate how it can serve as a useful thinking tool. In particular, I argue that the model not only allows us to theorise measures of metalinguistic awareness more clearly and easily, but that it can also capture tasks aimed at assessing other linguistic and cognitive abilities. The article concludes with a brief outlook on future research into metalinguistic awareness.

This paper explores Chalmers and Glasziou's (2009) notion of ‘research waste’ from healthcare research to examine what it can offer the field of applied linguistics. Drawing on examples from both disciplines, we unpack Macleod et al.'s (2014) five research waste categories: (1) asking the wrong research questions, (2) failing to situate new research in the context of existing research, (3) inefficient research regulation/management, (4) failing to disseminate findings, and (5) poor research reporting practices. We advance this typology to help applied linguists identify and reduce avoidable research waste and improve the relevance, quality, and impact of their research.

The increasing recognition of the limitations of physical mobility programs has led Foreign Language departments to consider online approaches such as Virtual Exchange (VE) and Blended Mobility as alternatives in international education. These online approaches have the potential to promote inclusion and diversity by providing opportunities for student cohorts who are unable to participate in traditional mobility programs. However, there are still challenges and barriers that need to be addressed, related to foreign language competence, digitalization, and structural gaps in educational systems. In this paper, I review the arguments and the evidence for and against the belief that VE can be a force for greater inclusion in international learning, before going on to explore the issue of equity of engagement in VE projects.

The invitation to speak at this conference on corpora and data-driven language learning (DDL) at COSEDI, the University of Grenoble, was received at the beginning of February 2023. ChatGPT had been released on 30 November 2022 and it was already becoming obvious that this technology would present revolutionary opportunities and challenges for corpus applications to language learning. Through a limited number of case studies – the Collins Cobuild Dictionary, a data-driven workshop for academic writing for research students, and the replication of the tasks used in the workshop, using ChatGPT – this presentation selectively highlights the trajectory of DDL from its beginnings to the present day and takes a look into a possible future with large language models (LLMs) such as ChatGPT.

This agenda identifies future research trajectories for the corpus revolution, proposing five specific research tasks designed to explore and advance the application of corpus linguistics in language education. These tasks focus on: (1) contrastive data-driven learning, (2) the development of corpus research for informing national language curricula, (3) the use of artificial intelligence for corpus informed language teaching and learning, (4) the reconsideration of the design and development of pedagogical corpora, and (5) the need for stakeholder engagement with corpus research design. Addressing these tasks requires a unified and collaborative effort as they sit at a number of key intersections in corpus applications to language pedagogy. We ask scholars executing them to engage in broad and cooperative research to meet the evolving needs of learners globally, to examine the potential of corpus linguistics for addressing new challenges in language education, and to influence and shape future directions in applied linguistics.

Increased work connectivity and study mobility over national boundaries in recent decades has led to a shift in the kind of English as a Second Language (ESL) instruction implemented in many educational institutions. Instruction to develop learners’ general English language proficiency may appear as a time-consuming and abstract endeavour. Instead, many institutions implement English for Specific Purposes (ESP), including English for Academic Purposes (EAP) type instruction. In ESP, the aim is to help students develop the specialized academic and work-related linguistic registers they need to function in target settings where English is used as a medium of instruction or in businesses and workplace communication. A great deal of ESP research has now been conducted to build linguistic descriptions of specialized registers. Rather less research has focused on the learning of such specialized registers. This article identifies areas for a research agenda to develop an understanding of learning a specialized register. It sets out two sites for enquiry, namely, learning in a target workplace or disciplinary study setting and learning in instructed ESP, and four topics for enquiry, namely, processes of learning, conditions for learning, learning trajectories, and transfer of learning. Example tasks are suggested for research into learning in target settings.

This article advocates for the expansion of research into the topic of well-being in language education. It begins by outlining key definitional concerns and then moves to outline general issues and gaps in the current body of research such as a need for a diversification in research in social contexts, working conditions, languages, cultures, as well as a clarification of the domain specificity of the construct. In the main body of the paper, three core specific areas are outlined in detail with suggestions of not only what could be researched but how this could be done in concrete empirical terms. Task 1 concerns the dynamism of well-being across different timescales and how those interact. Task 2 focuses on the relationship between self-efficacy and well-being as an example of one core individual difference that could impact well-being development. Task 3 reflects on the possible interplay between learner and teacher well-being. The article ends by arguing for language teacher well-being to receive the urgent and critical attention that it deserves across the whole range of contexts and individuals who identify as language educators.

This review on English language teaching (ELT) in Singapore examines 159 empirical research studies published between 2017 and 2023 in both internationally recognised peer-reviewed journals and less well-known regional journals. With this comprehensive review, we aim to raise awareness of ELT research in Singapore for international, regional, and local readership. This will also serve as a starting point for educators, scholars, and researchers to investigate ELT in Singapore. The review yielded five themes: teaching the language skills; multiliteracies and technology; bi/multilingualism/bidialectalism and English; English as an academic language; and teacher education for ELT. While there is continuity from the last two reviews of research from Singapore in 2009 and 2021, reflected in the single theme of teaching language skills, the other themes represent new directions.
