J.D. Brown (JD) served as the author of an instructional column titled "Statistics Corner" in the "Shiken": JALT "Testing & Evaluation SIG Newsletter" for an extensive period spanning over two decades, from 1997 to 2019. This publication was under the auspices of the Testing and Evaluation Special Interest Group,…

The purpose of this review was to summarize the behavior-analytic literature on the emergence of untrained second language skills and to provide recommendations for future research focused on second language acquisition. Seventeen distinct studies were included in the review. These studies implemented a variety of teaching methods (e.g., tact,…

Complex Dynamic Systems Theory (CDST), an instantiation in applied linguistics of complexity epistemology that transcends disciplinary boundaries, has gained much traction and momentum over the last decade, finding expressions in a fast-growing number of empirical second language developmental studies. However, the literature, while rapidly…

Purpose: This meta-analysis study aimed to determine the optimal level of talker variability in training to maximize second-language speech learning. Method: We conducted a systematic search for studies comparing different levels of talker variability in nonnative speech training, published through July 2024. Two independent reviewers screened…

The growing diversity among test takers in second or foreign language (L2) assessments makes the importance of fairness front and center. This systematic review aimed to examine how fairness in L2 assessments was evaluated through differential item functioning (DIF) analysis. A total of 83 articles from 27 journals were included in a systematic…

Process genre approach (PGA), which integrates the strengths and drawbacks of product approach, process approach and genre approach, has long been proved effective in scaffolding EFL writing teaching in culturally divergent contexts. China with the largest EFL learner population worldwide likewise places rising attention to PGA, yielding a body of…

The Common European Framework of Reference (CEFR) is a crucial reference framework for informing teaching, learning and assessment that has achieved worldwide prominence in language education. However, there have been concerns raised regarding the breadth of its influence across different domains and countries. Using a bibliometric approach, a…

This bibliometric study examines the characteristics of the overall research trends, patterns of productivity, and publications on "assessment in second language pronunciation". Bibliometric data were retrieved from Web of Science (WoS on 1 September 2021 and the results of the study reveal that the first publication appeared in 1993…

This systematic review evaluated the effects of foreign tact training on emergent learning outcomes in ten published studies. We also conducted a meta-analysis of aggregate data from seven studies comparing outcomes of foreign tact training with other verbal operant procedures. The preliminary findings indicated foreign tact training produced…

This study synthesized the research on listening instruction (LI) and its effectiveness on L2 learners' listening competence development based on studies published from 1980 to 2019. After a literature search, well-designed studies that involved not only experimental or quasi-experimental and control groups but also pretests and posttests were…

English textbooks are the most pivotal learning materials in the EFL context. However, in Vietnam, English textbooks for general education are randomized by schools, which arouses a problem of whether they are equivalent for students to gain the same proficiency. This study attempts to report the differences in lexical demands and features,…

Grounded in Vygotsky's Sociocultural Theory, Dynamic Assessment (DA) can provide fine-tuned information regarding learners' development and opportunities to promote further development. Vocabulary knowledge, because of its complex nature, requires a more sensitive assessment, especially for second language (L2) learners. This systematic literature…

English Medium Instruction (EMI) is widely used as a method of simultaneously delivering discipline-specific content and instruction in English as a Foreign Language. Meanwhile, among factors related to learner affect, learner motivation is known to be a key predictor of success in the classroom. A systematised review was conducted to gain an…

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 relationship between working memory (WM) and second-language (L2) reading has been extensively examined, with mixed results. Our meta-analysis models the potential impact of under-researched variables considered to moderate this relationship. Results from 74 studies (228 correlations) showed a significant, small relationship between WM and L2…
