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…

This case study examines the key steps and challenges that were involved in a mixed methods research project relating to Japanese first-year medical students' English academic vocabulary learning. Conducting mixed methods research can be both conceptually and administratively challenging under any circumstances. However, this study was especially…

This systematic review synthesizes recent trends in English for Specific Purposes (ESP) research, examining 149 empirical studies published in Social Sciences Citation Index (SSCI) journals between 2014 and 2023. Employing a six-dimensional coding framework, we investigated participants, pedagogical methods, research methods, research foci,…

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…

Second language (L2) motivation has long been regarded as one of the requisites for and predictors of success in L2 learning. The scholarship on L2 motivation has grown steadily over the past 60 years, yielding several theories through a range of methods. Building upon this tradition, this paper proposes a methodological contribution to the…

This paper evaluates the use of Factor Analysis (FA) in English education research in Korea and suggests improvements in methodology. A detailed coding protocol was used to review 179 FA cases from 12 major English education journals (2014-2023). The review identified several key issues, including small sample sizes and lenient criteria for sample…

Meta-analytic studies of second language (L2) learning typically employ a classic approach to meta-analysis. Although the classic approach can clarify findings, a multivariate, multilevel meta-analysis (3M) approach increases transparency by accounting for (a) dependencies in the evidence presented by primary studies, (b) methodological…

Mobile technologies and the widespread application of mobile devices have become significant in educational settings. Mobile-assisted language learning (MALL) is a thriving field of study in language learning and teaching contexts in Iran. This study investigates the current research trends and characteristics of MALL studies in Iran, identifying…

Causal inference is a fundamental goal of many research endeavors, including scholarship in the field of language education and learning. Randomized controlled trials are considered an ideal design to test causal claims, but not all claims can be subjected to experimental treatment due to ethical and practical constraints. In this article, we…

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…

This study reviews 71 high-quality studies of massive open online courses focused on languages (LMOOCs) that were published from the inception of LMOOCs to 2021. The purpose of this study is to gain a deeper understanding of the current state of research and identify fruitful directions for future LMOOC research. First, we reviewed three basic…

This qualitative Case Study explores learning motivation in highly motivated learners of English using the motivational angels concept to analyze their beliefs and perceptions about how teachers can build learning motivation in their students. This Case Study discusses lessons learned from empirical research conducted in a rural high school using…

Learner autonomy is a vibrant and diverse field. In its approximately 40-year history, it has drawn liberally on theoretical constructs and research methodologies from other disciplines. In turn, it has contributed to the field of applied linguistics by drawing attention to the fundamental importance of understanding the language learner as an…

Technology-mediated learning has become a valuable tool, especially in the English language classroom. Nowadays, mobile learning is considered a significant educational tool for promoting education among learners. Several recent studies have attempted to examine different aspects of mobile learning. The size of the experimental group, and the…

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…
