English Medium Instruction (EMI), as a phenomenon occurring in the non-Anglophone world, has been matched by a growth in research output on the topic and is now an important and established field of study. A great deal of research attention has been devoted to attitudes held by the key stakeholders in this form of education: teachers, students, and policy makers. Yet, there are many other important questions that remain unanswered, the most important of which are: What are the outcomes of this form of instruction? What is the social and economic impact of EMI? How can EMI teachers improve their teaching? And how can learners help themselves to improve their learning?

This paper considers the issue of the norm in the context of learner corpus research and its implications for foreign language teaching. It seeks to answer three main questions: Does learner corpus research require a native norm? What corpus-derived norms are available and how do we choose? What do we do with these norms in the classroom? The first two questions are more research-oriented, reviewing the types of reference corpora that can be used in the analysis of learner corpora, whereas the third one looks into the pedagogical use of corpus-derived norms. It is shown that, while studies in learner corpus research can dispense with a native norm, they usually rely on one, and that a wide range of native and non-native norms are available, from which choosing the most appropriate one(s) is of crucial importance. This large repertoire of corpus-derived norms is then reconsidered in view of the reality of the foreign language classroom.

Research into peer interaction continues to grow and new findings with new designs have been reported. However, there remain theoretical and methodological issues that replication studies can address. In this article, I first discuss theoretical frameworks that have been used to investigate peer interaction, namely, interactionist, sociocultural, and psychological. I explain that, regardless of theoretical frameworks, peer interaction effectiveness has been at least partly accounted for by the ways in which learners temporarily shift their attention to linguistic issues during meaningful interaction, via peer feedback or language-related episodes (LREs). Current research also suggests that learner attitudes mediate this interactional behavior. To fill the gaps in this issue, I make methodological suggestions for replication research of Adams, Nuevo, & Egi (2011) and Philp, Walter, & Basturkmen (2010), including intervention materials, transcript analysis, statistical design, and internal validity control. I conclude the paper with pedagogical implications that may arise from replication studies.

Classroom research has long been recommended as a fruitful avenue for English language teaching (ELT) in applied linguistics. Yet recognition of the value of practitioners exploring their own praxis has only recently come to the fore. In this plenary, I focus on Exploratory Practice, a form of ‘fully inclusive practitioner research’, in which learners as well as teachers are invited to integrate research and pedagogy. Drawing on studies from around the world, I spotlight the potential of learners and teachers to contribute to debates in the fields of language teaching and learning, applied linguistics and social sciences alike. This co-production between learners and teachers illuminates the nexus of research and pedagogy (praxis), providing plentiful puzzles for exploration.

A great deal of research on second language (L2) input has provided useful linguistic evidence for the development of generalizations about and hypotheses on the usage-based nature of L2 knowledge. However, despite the fact that classrooms are one of the most ubiquitous sites of L2 learning, we still know very little about the linguistic quality of naturally-occurring classroom interactions and their consequential role in shaping learners’ linguistic repertoires (Ellis, 2016). These data are needed in order to understand how differences in L2 classroom interactional activities affect L2 learner language. This is the focus of the set of research tasks I lay out in this paper. After a brief overview of usage-based research on language and a summary of the methodological contributions of conversational analysis (CA) and interactional linguistics (IL) to such research, I will explicate a research agenda comprising five tasks for investigating the links between L2 classroom interaction and L2 learners’ developing linguistic repertoires. By making clear the interrelationships between teaching and learning, findings from the studies will offer new insights into L2 pedagogy and the key role that L2 teachers play in designing the linguistic environments of their learning contexts and shaping learners' linguistic repertoires.

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 pedagogical materials (henceforth materials). Then, we focus on seven qualitative research tasks across three thematic areas, namely materials use and: (A) language pedagogy, (B) classroom interaction, and (C) language diversity, culture, and power. The first section on pedagogy outlines research tasks on: (1) the roles of materials in classrooms, (2) the influences of materials on practicing educators’ expertise, and (3) how language teacher education programmes address materials use. The second section on classroom interaction proposes inquiry into: (4) polysemiotic patterns of materials-in-interaction, and (5) the expected and unexpected outcomes of materials regarding students’ target language use. The third section focuses on: (6) teachers’ and learners’ responses to diverse linguistic varieties and cultures represented in materials, and (7) instructional materials used in language policy and planning endeavours. Throughout this article we reference interdisciplinary connections to curriculum studies, cultural studies, sociology, and materials scholarship in general education. The seven research tasks are critical next steps for understanding materials use – a vast new field that promises to advance language education practice and theory.

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 language and demonstrate the importance of studying its patterned nature. The studies also illustrate how corpora and corpus-analytic techniques can allow us as applied linguists to contribute to solving problems in other disciplines (such as legal scholarship or music theory) and hope to thereby encourage more interdisciplinary research collaborations between corpus linguists and scholars from other fields.

We closely replicated Wu and Ortega (2013), who found that an elicited imitation test (EIT) reliably distinguished low-level from high-level language abilities among instructed second language (L2) learners of Mandarin Chinese. The original study sampled learners (1) from second-level courses to represent low-level language abilities and (2) from third-, fourth- and graduate-level courses to represent high-level language abilities. Results showed high-level learners outperformed low-level learners on the Mandarin EIT. Our close replication used Wu and Ortega's (2013) materials and procedures in order to understand (1) the extent to which this EIT can additionally distinguish between finer-grained language abilities and (2) the ways in which the broad grouping of language abilities in the high group may have contributed to the findings. Sixty-five instructed L2 learners from four instructional levels were assigned to one of three groups: Beginner (first-level courses), Low (second-level courses), High (third- and fourth-level courses). Consistent with the original study, our results showed clear between-group differences, indicating that the EIT can distinguish between both broad (beginner vs high) and finer-grained (beginner vs low, low vs high) language abilities. These results are discussed in light of the original study's findings with implications for proficiency assessment in second language acquisition (SLA) research.

Investigations of crosslinguistic effects in second language acquisition (SLA) have contributed rich understandings about the ways in which prior language knowledge and experience can influence additional language learning. Building on this work, one recent line of research has examined the extent to which SLA findings about crosslinguistic influence can be used to improve L2 learning, indicating that explicit instruction tailored to address the nature of the crosslinguistic learning problem can benefit L2 performance. At the same time, however, this line of inquiry is relatively novel and under-researched. The aim of this paper, therefore, is to suggest further research which might advance knowledge and understanding about the ways in which explicit instruction can facilitate second language (L2) learning of crosslinguistically difficult target features. To this end, I lay the ground for a series of close replications designed to understand the role of prior language knowledge and experience in L2 learning: Ellis and Sagarra (2011) and Tolentino and Tokowicz (2014). These studies were selected because they are grounded in empirical SLA research and SLA theory. In addition, the selected studies facilitate replication because they have either (i) made their data collection materials available in digital repositories or (ii) have robustly described their design and provided the stimuli used.

Mercer (2018) makes a compelling argument for the urgent need to further research teacher psychology, focussing on language teachers. While there has been considerable research on language learner psychology and with considerable focus on individual differences (IDs), there have been comparatively few studies into language teacher psychology. Mercer (2018, p. 506) highlights that teachers are among the most important stake holders in the language learning and teaching process. Therefore, it is essential to understand the psychology of both learners and teachers to achieve the best learning outcomes.

This paper reviews and discusses research on notetaking during academic listening conducted in both first (L1) and second language (L2) contexts and is organized into two main categories: research that is beginning to impact English for academic purposes (EAP) classrooms and that which has yet to make an impact on EAP, but should. Overall, I assert that, while some relevant research on notetaking is reaching EAP classrooms, there is an abundance of knowledge from L1 contexts as well as a number of unexplored areas that have potential to improve instruction and student ability. Throughout the paper, I hypothesize why certain research findings are not being applied in classrooms. In concluding, I provide suggestions for how researchers and teachers might further support colleagues in applying research findings.

What does it mean to learn a word? How can we tell when a sequence of letters or sounds becomes a word in the mind of the learner? While many second language (L2) vocabulary teaching and learning studies continue to use traditional vocabulary tests to measure learning (such as multiple choice, translation, gap-fill), these measures tend to come short when researchers want to address theoretical questions about the nature of L2 word knowledge. In the present paper, I argue for conceptualising word learning as lexicalisation, which necessitates the use of alternative approaches to measuring learning. I then propose approximate and conceptual replications of two theoretically motivated L2 word learning studies, Elgort (2011) and Qiao and Forster (2017), that used the Prime Lexicality Effect as a measure of lexicalisation of deliberately learned L2 words.

The Competition Model has served as a functional explanation of cross-linguistic influence and transfer for more than 30 years. A large number of studies have used the Competition Model to frame investigations of sentence processing strategies in different types of bilingual and multilingual speakers. Among the different bilingual speakers investigated, Mandarin Chinese and English bilinguals represent a clear testing ground for the claims of the Competition Model. This is because of purportedly stark contrasts in sentence processing strategies between the two languages. Previous studies investigating sentence processing strategies of English L2 and Mandarin L2 bilinguals suggests forward transfer of L1 cues to the L2, moderated by L2 proficiency. In this paper, we argue for replication of two of these studies, namely Liu, Bates, and Li (1992) and Su (2001). These studies continue to be cited today as evidence of differences between English and Mandarin sentence processing strategies which is in turn taken as support for the predictions of the Competition Model. However, both studies presented methodological limitations in terms of measures of proficiency, participant and stimuli selection, and the statistical analysis. We suggest approximate replication of both of these studies and provide suggestions for how such replications might be conducted.

This paper makes the case for close and approximate replications of Erlam (2005) and a conceptual replication of Roehr-Brackin and Tellier (2019). The two studies recommended for replication are informed by research on explicit and implicit knowledge, learning and teaching. They are ecologically valid classroom studies with either adolescent or child learners as participants and thus investigated as yet relatively under-represented populations in the field of instructed second language acquisition (SLA). Erlam (2005) identified a levelling effect of a particular method of explicit instruction, while Roehr-Brackin and Tellier (2019) showed that language-analytic ability has a role to play even in younger children's language learning. The researchers’ approaches duly reflect the need to take into account cognitive individual learner differences when working in intact classrooms. As the findings of each of the original studies have potentially profound implications for theory and practice in the field, replication is deemed both timely and desirable. In order to facilitate this endeavour, the key features of the original studies are summarised, and specific proposals on the methodological characteristics of suitable replication studies are put forward.
