Research has demonstrated that features of lexical and lexicogrammatical use are important predictors of productive second language (L2) proficiency (e.g. Kyle et al. 2018). While some features of lexical use have been studied with L2s other than English (e.g. Tracy-Ventura 2017), multivariate lexical and lexicogrammatical approaches in these L2s…

The present study performs a three-level meta-analysis to investigate the overall effectiveness of automated writing evaluation (AWE) on EFL/ESL student writing performance. 24 primary studies representing 85 between-group effect sizes and 34 studies representing 178 within-group effect sizes found from 1993 to 2021 were separately meta-analyzed.…

This meta-analysis evaluated the effectiveness of data-driven learning (DDL) among low-proficiency L2 English learners, addressing the mixed results found in previous meta-analyses. The study incorporated 38 studies involving 2085 participants, yielding 37 effect sizes from control-experimental (C/E) studies and 42 from pre- and post-test (P/P)…

Form-Focused Instruction (FFI) has been extensively studied, yet past experimental results are often inconsistent or even contradictory. Overly simplistic examinations of grammatical complexity and learner characteristics (e.g., L2 English proficiency) may have fueled the confusion, limiting understanding of how different FFI techniques can be…

Language proficiency is multi-componential in nature and, according to many SLA researchers and L2 practitioners, is best captured by the concepts of complexity, accuracy, and fluency (CAF). Two of the three studies reported in this paper adopted the Cognition Hypothesis (Robinson, 2003) as the means to address the question of whether increasing…

Syntactic complexity has been extensively approached in the fields of corpus linguistics and academic discourse studies. However, works focusing on disciplinary variation in terms of linguistic complexity and comparison of professional and novice academic writing are scarce. Addressing these issues is likely to have important implications for…

This meta-analysis offers a snapshot of thirty-five years (1980-2015) of research on instructed second language acquisition (ISLA). Fifty-four empirical studies involving a total of 5,051 second language learners -- sampled from six applied linguistics journals, "Applied Linguistics, Language Learning, Language Teaching Research,"…

Early research on the Aspect Hypothesis yielded a rigid developmental sequence for the acquisition of grammatical aspect, in which developing L2 learners applied morphemes to mark aspect in accordance with the inherent lexical aspect of verbal prototypes. While studies from a variety of L2 backgrounds have amassed evidence for this hypothesis,…

Edmodo has a significant role and place in the language teaching and learning contexts. However, there is no conclusive evidence on how Edmodo affects the language learning process. This study aims to present a review of the studies to make recommendations for teachers and researchers for further research. The study concludes that learners and…

Despite extensive theoretical and empirical research, we do not have estimations of the magnitude of sensitivity to grammatical information during L2 online processing. This is largely due to reliance on null hypothesis significance testing (Plonsky, 2015). The current meta-analysis draws on data from one elicitation technique, self-paced reading,…

We reviewed literature on the school-related writing of students in English-dominant settings whose native languages were other than English to identify 2 kinds of difference: (a) among language minority (LM) students differing in oral English proficiency and (b) between LM and native English-speaking students. Sixteen studies met selection…

The present article offers a review of the existing literature on L2 gains arising from participation in a study abroad (SA) experience. The purpose of this article is (1) to provide a general overview of research findings on the influence of time abroad on L2 development and (2) to identify the areas which need further research within the SA…

This study examined how key factors of FFI (degree of explicitness, L1 similarity, proficiency level, and grammar type) influence the accuracy of production. A total of 22 experimental studies, all of which had Korean participants and productive assessments of speech or writing, were selected for analysis. Results revealed that explicit grammar…

This meta-analysis aims at investigating the impact of English language teaching practices on language outcomes. The literature search yielded 90 meta-analyses that were published between January, 1995 and December, 2019. The current study analyzed 90 meta-analysis and these studies comprised 3496 studies, 7870 effect sizes and nearly 700,000…

Songs have been a common feature of young learner classrooms for decades, and numerous publications describe how songs should be employed in order to improve motivation and facilitate the acquisition of various aspects of language, including vocabulary, grammar, pronunciation, and listening skills. However, empirical research examining the effects…
