Corrective feedback on second language (L2) writing has remained one of the most heavily studied areas in applied linguistics, yet clear guidance for practitioners about how to provide it most effectively remains limited. Previous studies have meta-analysed written corrective feedback (WCF) research revealing conflicting findings in how WCF affects development in L2 writers’ accuracy over time. This study provides a needed update in light of a recent increase in (quasi)experimental WCF studies. It features several methodological advances by introducing a Bayesian approach to conducting a meta-analysis, which provides a more valid picture of the generalizable effects. The analysis allows distinction – for the first time at a meta-analytic level – between short-, medium-, and long-term effects of WCF. Results aggregate data from an initial 52 primary studies that utilized control groups revealing robust evidence of the durability of moderate effectiveness of WCF over time and deeper insight into the relative effectiveness of various types of WCF (e.g. direct, indirect, metalinguistic – all yielding similar effect sizes) across research contexts, writing task types, target error types, and instructional characteristics. We conclude with recommendations to help continue methodological advances in this domain.

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 years of language engagement research. To ensure robust coverage, we searched 21 major journals on second language acquisition (SLA) and applied linguistics and identified 112 reports satisfying our inclusion criteria. The results of our analysis of these reports highlighted the adoption of heterogeneous methods and conceptual frameworks in the language engagement literature, as well as indicating a need to refine the definitions and operationalizations of engagement in both quantitative and qualitative research. Based on these findings, we attempted to clarify some lingering ambiguity around fundamental definitions, and to more clearly delineate the scope and target of language engagement research. We also discuss future avenues to further advance understanding of the nature, mechanisms, and outcomes resulting from engagement in language learning.

This study set out to re-examine the effectiveness of study abroad programs in second language (L2) acquisition through a multi-level meta-analysis. Overall, 42 primary studies published between 1995 and 2019 were identified, and in total 283 effect sizes were meta-analysed. This study implemented a three-level random effects model to account for the clustered, mutually dependent effect sizes often nested in the primary studies of L2 study abroad research. The results indicated a medium-to-large effect (g = 0.87) on study abroad language programs. Essentially, the featured moderators in general explained more heterogeneity variances at level 3 (i.e. the between-study level) than at level 2 (i.e. the within study level). For study abroad language learners, language acquisition is optimal when learners, in particular those of a lower proficiency level, take both formal and content-based language courses while living with host families. Learners’ age and pre-program training may not moderate the effectiveness of study abroad language programs. Importantly, this study further established that the length of study abroad programs are positively associated with learners’ language gains, but that an extended and prolonged domestic program does not necessarily lead to such gains. Research and pedagogical implications are further discussed based on the research findings.

Task-based language teaching (TBLT) is an empirically investigated pedagogy that has garnered attention from language programs across the globe. TBLT provides an alternative to traditional grammar translation or present-practice-produce pedagogies by emphasizing interaction during authentic tasks. Despite several previous meta-analyses investigating the effect of individual tasks or short-term task-based treatments on second language (L2) development, no studies to date have synthesized the effects of long-term implementation of TBLT in authentic language classrooms. The present study uses meta-analytic techniques to investigate the effectiveness of TBLT programs on L2 learning. Findings based on a sample of 52 studies revealed an overall positive and strong effect (d = 0.93) for TBLT implementation on a variety of learning outcomes. The study further examined a range of programmatic and methodological features that moderated these main-effects (program region, institution type, needs analysis, and cycles of implementation). Additionally, synthesizing across both quantitative and qualitative data, results also showed positive stakeholder perceptions towards TBLT programs. The study concludes with implications for the domain of TBLT implementation, language program evaluation, and future research in this domain.

Glossing is a widely used and examined vocabulary learning tool, and one of the major branches of glossing research has compared the relative effects of first language (L1) and second language (L2) glosses on reading comprehension and vocabulary learning. However, the findings in this literature have not been consistent, calling for a comprehensive and systematic review. To this end, we conducted a meta-analysis to investigate the relative effects of L1 and L2 glossing on L2 reading comprehension and L2 vocabulary learning. Based on 78 effect sizes gathered from 26 studies representing 30 independent samples (N = 2,189), we found that L1 glossing was more effective than L2 glossing in general (Hedge’s g = .33, SE = .09, p < .001), but the effect size may vary depending on the target outcome measure. The relative effectiveness of L1 glossing was particularly supported by the results of immediate posttests of vocabulary, rather than delayed posttests of vocabulary and reading comprehension tests. Further, among a few selected moderator variables, the results of meta-regression revealed that learners’ L2 proficiency level significantly influenced the average effectiveness, such that L1 glossing is particularly effective for beginner learners compared to those with intermediate or higher L2 proficiency levels.

Este trabajo realiza un meta-análisis de las tesis doctorales en el ámbito de la enseñanza/aprendizaje del español como lengua extranjera (ELE). Bajo un diseño longitudinal de tres años, analizamos 103 tesis leídas/defendidas entre 2017 y 2019. Concretamente, estudiamos ocho variables establecidas previamente que nos permiten identificar el estado actual de la metodología de investigación de dichas producciones científicas: el paradigma de investigación, la tipología de estudio, el método y el instrumento de investigación, la tipología de análisis, la temática y el contexto de investigación. Tras completar la fase de búsqueda y clasificación, analizamos las tesis disponibles en Internet que están alojadas gratuitamente en estas cuatro bases de datos en España: Dialnet, Teseo, Tesis doctorales en Xarxa (TDX), y Portal del Hispanismo del Instituto Cervantes. Aplicamos el análisis descriptivo para conocer la tendencia de las variables y el análisis inferencial para explorar la posible relación entre la variable dependiente (año de defensa/lectura) y las ocho variables consideradas. Los resultados del trabajo muestran una radiografía de la metodología de investigación y el comportamiento de las variables durante el periodo establecido. Con todo ello, nuestro trabajo enriquece las investigaciones precedentes y aporta un marco amplio de la trayectoria investigadora que se ha seguido hasta ahora en este ámbito.
