In this final article in this guest-edited issue on synergies in second language acquisition and teaching (SLA/T), we attempt to bring together the main content of this issue in an overall, combined synergy statement, concluding this project as a whole. Let us remind readers of the project: A shared effort by 17 scholars taking 11 different…

This pioneering piece of research on the situated study of language issues in the context of forced migration provides interdisciplinary insights into language as learned, used and lived by 12 Congolese refugees in Norway. It offers an innovative contribution to the field of SLA by bringing together structural, cognitive, social and critical…

This action research study explores the interplay between language acquisition and high school mathematics education, particularly for multilingual learners. The study challenges conventional, segregated approaches to math and language learning that emphasize formulaic memorization and algorithmic methods, contributing to the "math…

Nowadays, research in second language acquisition (SLA) is becoming increasingly interdisciplinary while many technical frontiers and research hotspots have emerged. Many studies focus on interdisciplinary topics, but few in-depth studies have been conducted on interdisciplinarity. This study examined the interdisciplinarity of SLA and the…

How language learners and teachers actually use "pedagogical materials" in classrooms is a 'groundbreaking' subject of applied linguistics inquiry (Tarone, 2014, p. 653), referred to in this research agenda article as "materials use." We begin with a theoretically-oriented overview of language education scholarship on…

This volume brings together original papers from language education scholars from around the world to explore, exemplify, and discuss the multiplicity of boundary crossing in language education. It emphasizes the potential of boundary crossing for expansive learning, and aims to generate new insights, through boundary crossing, into the complexity…

This article is structured around four questions related to the arts, language and intercultural education. Are the claims for the value of the arts over-stated? Does the use of the arts in the service of non-art outcomes run the risk of distorting the art form itself? Is there a danger that incorporating the arts in language education will…

Since the "Next Generation Science Standards" (NGSS) were released, K-12 science teachers have been figuring out how to extend related learning opportunities to all students, including multilingual learners (MLLs) who are new to speaking English. Elementary schools often prioritize math and English language arts, the subjects that are…

Migration, among the most important sociocultural phenomena of contemporary global societies, is complex, dynamic, and multifaceted. At the heart of migration is language, the indispensable agent of migration. Hence, in this article, a new sub-discipline of linguistics is presented, and that is 'migration linguistics'. It is the interdisciplinary…

This plenary speech provides an overview of applications of corpus research in several core areas of applied linguistics, including second language acquisition and language assessment. It does this by showcasing a number of recent studies carried out by or with involvement of the author. These studies all focus on phraseological aspects of…

The release of ChatGPT marked the beginning of a new era of AI-assisted plagiarism that disrupts traditional assessment practices in ESL composition. In the face of this challenge, educators are left with little guidance in controlling AI-assisted plagiarism, especially when conventional methods fail to detect AI-generated texts. One approach to…

The last two decades have seen a significant amount of interest in bilingual language learning and processing. A number of computational models have also been developed to account for bilingualism, with varying degrees of success. In this article, we first briefly introduce the significance of computational approaches to bilingual language…

The field of multilingual learner education has become increasingly complex, with longstanding efforts focused on promoting "access" to multilingual learners being criticized for failing to "transform" systems responsible for these students' marginalization. This essay brings clarity to the complex terrain of equity for…

Research on multilingualism and the acquisition of language(s) faces numerous challenges given its inherently interdisciplinary character. This discussion will focus on the notion of internal context, a concept that forcefully demonstrates the need for integrating linguistically-oriented research with cognitive research in general. Investigating…

This article discusses interdisciplinary approaches to help students overcome communication barriers by integrating performing arts in Business Communication courses. Companies emphasize a workforce with solid soft skills to succeed. International Business employs English; thus, practical communication skills in English provide access to jobs in…
