This paper puts forward a research agenda in the area of explicit and implicit knowledge and learning of second or additional languages. Based on a brief overview of reliable findings as well as open questions in the field, three agenda items are highlighted. First, valid and reliable measures of explicit and, in particular, implicit knowledge and…

Against the backdrop of greater emphasis on learner centredness and growing attention to learners' voices in recent decades, concerns have been raised over researchers' dominance in shaping research scope and findings. Whether it be quantitative, qualitative, or mixed-methods research, learners' voices are mostly absent at the methodological…

Mixed methods research, or mixed research, is an area with a great deal of promise for applied linguistics, especially given the field's diverse range of topics and methods. However, when mixed research mixes qualitative and qualitative methods, this can be problematic as researchers suppose this implies mixing mutually exclusive 'quantitative'…

Structural equation modeling (SEM), as a flexible and versatile multivariate statistical technique, has been growingly used since its introduction in the 1970s. This article presents a methodological synthesis of the characteristics of the use of SEM in L2 research by examining the reporting practices in light of the current SEM literature to…

At the turn of the new millennium, in an article published in "Language Teaching Research" in 2000, Dörnyei and Kormos proposed that 'active learner engagement is a key concern' for all instructed language learning. Since then, language engagement research has increased exponentially. In this article, we present a systematic review of 20…

Despite the importance of replication research in scientific fields, very few replications are conducted in applied linguistics (AL). To enhance language researchers' awareness of replications and provide a systematic evaluation of current replications, this study analyzed replication studies published in 92 AL leading journals from 1970 to 2021…

This reflective piece tells the story of how I started out doing Conversation Analysis (CA) and have been transitioning into doing mixed methods for some years now. My basic argument is that language learning talk is too complex a phenomenon to analyse using a single methodology. Specifically, it is extremely difficult to isolate from the…

Research on input processing and processing instruction has often employed a scoring method known as trials to criterion to observe the effects of instruction that emerge during training. Despite its common use in this research (see Fernández, 2021) this metric has never been evaluated critically. The present study first discusses several…

Research Methodology (RM) is the backbone of any TEFL (Teaching English as a Foreign Language) MA programme. Although a burgeoning body of research has investigated students' attitude towards research and RM course in various disciplines, students' attitudes towards research and research methods courses in TEFL research has remained a relatively…

We present a review of second language researchers' use of cluster analysis, an advanced statistical method still uncommon but increasingly used to identify groups or patterns in a dataset and to examine group differences. After describing key methodological considerations in conducting cluster analysis, we present a methodological synthesis of 65…

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…

The field of language documentation continues to grow, but an historic split between sign language documentation and spoken language documentation persists. In order to fully understand the linguistic context within a community, it can be necessary to overcome this split by designing language documentation projects to address threatened and…

Linguistic ethnography provides insight into how communication occurs between individuals and institutions, while situating these local actions within wider social, political and historical contexts (Copland & Creese, 2015) and has proven to be a particularly effective tool for developing our understanding of individuals' lived multilingual…

This article examines the use of the repertory grid technique as a method to investigate learner perceptions in language education research. An important issue raised in this article concerns how far a researcher's agenda may be unintentionally imposed onto a research study which is investigating learners' perceptions, and how far the ensuing data…

Augmentative and alternative communication (AAC) is a core component of speech pathology practice. However, international literature has highlighted that speech language pathologists (SLPs) may not feel confident or competent in this area. Confidence and competence are critical factors in therapy as they can impact the quality-of-service…
