English language teaching and English-medium instruction

The role of English language teaching (ELT) in English-medium instruction (EMI) can vary widely depending on education policy objectives and teachers’ responses to EMI students’ language and learning needs. In this paper, we provide a narrative review of a growing number of studies reporting language-related challenges as the foremost barrier to successful implementation of EMI. Such research highlights the fundamental roles that English for Academic Purposes (EAP) and English for Specific Purposes have in the provision of targeted language support for EMI students. Based on this review, we set a future research agenda, calling for explorations into the efficacy of English language programs for supporting EMI students to reach educational outcomes. We also call for explorations of greater collaboration between English language practitioners and content lecturers to ensure the right type of language support is being provided to students. The paper ends with a discussion for the need to reposition EAP as English for Specific Academic Purposes to ensure students’ specific academic needs are met. Essentially, universities offering EMI will need to account for their unique institutional characteristics to ensure ELT provision is central in organizational and curricular structures; otherwise, they may be setting their own students up to fail

Global Englishes and TESOL: an editorial introduction to innovating research and practice

This editorial introduction to the special issue on Global Englishes and TESOL (Teaching English to speakers of other languages) explores the shifting landscape of English language teaching in response to English's role as a global lingua franca. The increasing diversification of English speakers and contexts challenges traditional TESOL practices, which have long centered on native speaker norms. This special issue includes 15 articles that critically examine the theoretical foundations of Global Englishes, the integration of these concepts into curricula, and the need for innovative research designs to support their implementation. These articles discuss how Global Englishes can address linguistic inequities, promote social justice, and reshape English language education by focusing on real-world language use. The collection emphasizes the need for collaboration between researchers and practitioners to ensure that pedagogical approaches reflect the diverse linguistic realities of English learners today. Additionally, it highlights the barriers posed by standardized testing, textbook content, and entrenched native speaker ideologies. By advancing empirical research and showcasing diverse global perspectives, this special issue aims to push the boundaries of Global Englishes scholarship and inspire meaningful, practical innovations in TESOL

Global Englishes and language teaching: a review of pedagogical research

The rise of English as a global language has led scholars to call for a paradigm shift in the field of English language teaching to match the new sociolinguistic landscape of the 21st century. In recent years a considerable amount of classroom-based research and language teacher education research has emerged to investigate these proposals in practice. This paper outlines key proposals for change in language teaching from the related fields of World Englishes, English as a lingua franca, English as an International Language, and Global Englishes, and critically reviews the growing body of pedagogical research conducted within these domains. Adopting the methodology of a systematic review, 58 empirical articles published between 2010-2020 were short-listed, of which 38 were given an in-depth critical review and contextualized within a wider body of literature. Synthesis of classroom research suggests a current lack of longitudinal designs, an underuse of direct measures to explore the effects of classroom interventions, and under-representation of contexts outside of university language classrooms. Synthesis of teacher education research suggests future studies need to adopt more robust methodological designs which measure the effects of Global Englishes content on teacher beliefs and pedagogical practices both before and throughout the program, and after teachers return to the classroom

Southeast Michigan Local Road Concrete Pavement Durability Study

Counties and cities in Southeast Michigan have used concrete pavements for nearly 100 years to provide long-lasting, durable streets and roads. Issues of concrete durability have arisen with some of the pavements built after 1990. In order to evaluate the causes of spalling and other deterioration methods, the National Concrete Pavement Technology Center (CP Tech Center) was asked to study the concrete from a number of the pavements, evaluate the causes of the distress, and offer recommendations for improvements. Of particular concern are the roles of coarse aggregate type (limestone or blast furnace slag), alkali-silica reactivity (ASR), and the air entrainment system in the hardened concrete on the joint deterioration distresses that are being observed

Generative AI and English language teaching: A global Englishes perspective

Generative AI (GenAI) offers potential for English language teaching (ELT), but it has pedagogical limitations in multilingual contexts, often generating standard English forms rather than reflecting the pluralistic usage that represents diverse sociolinguistic realities. In response to mixed results in existing research, this study examines how ChatGPT, a text-based generative AI tool powered by a large language model (LLM), is used in ELT from a Global Englishes (GE) perspective. Using the Design and Development Research approach, we tested three ChatGPT models: Basic (single-step prompts); Refined 1 (multi-step prompting); and Refined 2 (GE-oriented corpora with advanced prompt engineering). Thematic analysis showed that Refined Model 1 provided limited improvements over Basic Model, while Refined Model 2 demonstrated significant gains, offering additional affordances in GE-informed evaluation and ELF communication, despite some limitations (e.g., defaulting to NES norms and lacking tailored GE feedback). The findings highlight the importance of using authentic data to enhance the contextual relevance of GenAI outputs for GE language teaching (GELT). Pedagogical implications include GenAI–teacher collaboration, teacher professional development, and educators’ agentive role in orchestrating diverse resources alongside GenAI

A comparison of content learning outcomes between Japanese and English medium instruction

In the growing body of English medium instruction (EMI) research, few studies have directly compared the effects of medium of instruction on subject learning. This study compares direct measures of content knowledge and perceptions of knowledge acquisition for students studying Chemistry via English (n = 27) and Japanese Medium Instruction (JMI) (n = 26). Data were collected at a university in Japan where Chemistry courses were taught in both Japanese and English as part of a parallel program offering the same undergraduate curriculum in either of the two languages of instruction. An analysis was undertaken of students’ learning outcomes measured by pre-post course content tests. These measurable test outcomes were triangulated with data from student interviews (n = 17) to identify differences in the learners’ perceived experiences according to the medium of instruction. While the quantitative results revealed no significant overall differences in the adjusted post-test scores between EMI and JMI students, the qualitative data offered more detailed insight into the participants’ perspectives of content learning, highlighting unique challenges faced only by the EMI group. Findings point to implications for educational provision in contexts where the global trend of EMI has largely been unaccompanied with research evidence on its cost-effectiveness

Content knowledge attainment in English medium instruction: does academic English literacy matter?

This study investigates the relationship between students’ English language proficiency, their reported levels of academic English literacy, prior content knowledge and their attainment of content knowledge in English medium instruction (EMI). The study also examines students’ perceptions of difficulties with academic English literacy at different levels of English language proficiency. Pre-course and post-course content tests were administered to 27 EMI students in an introductory Chemistry course at a university in Tokyo, Japan. The test results were triangulated with data from a quantitative measure of reported academic literacy and follow-up interviews to explore perceptions of ease and difficulties for academic language skills (i.e. reading, listening, speaking and writing). The quantitative findings indicated that students’ proficiency statistically significantly predicted post-test scores. Interviews with students corroborated this finding, illustrating the specific difficulties in academic language literacy faced by students with lower proficiency. However, proficiency alone did not determine success as other factors, such as previous exposure to EMI and prior content knowledge, played significant roles. The study found a non-linear relationship between reported difficulties with academic English literacy and test outcomes, indicating that students who reported fewer academic difficulties were not necessarily more successful in gaining content knowledge than those facing significant challenges in academic language tasks. The findings emphasise that academic support in EMI programs should not solely focus on test outcomes but also address the broader challenges students face with academic English literacy. Implications are discussed regarding language support, EMI curriculum planning and future research directions

Researching EMI policy and practice multilingually: reflections from China and Turkey

In the field of English medium instruction (EMI), multilingual research approaches are crucial to carrying out effective and ethically responsible research, because EMI policies and practices are inherently multilingual. This paper is a partial replication study that adopts a ‘researching multilingually’ analytical framework to interrogate the challenges and affordances of using multiple languages during two EMI research projects. In the project in Turkey, the lead researcher, who is an English-Turkish bilingual, analysed policy documents (n = 145) and interview data (n = 67) drawing on her knowledge of both languages. Additionally, 85 EMI classroom observations were conducted. In the project in China, the research team of two L1 English speakers and two L1 Chinese speakers investigated 93 bilingual policy documents and conducted interviews with 26 policy arbiters by drawing on both languages during data collection and analysis. Together, these reflections highlight how multilingual approaches can be utilised throughout the research process, from team formation, research design, data collection, data analysis, and presentation of findings in research reports
