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…

This article takes a meta-analytic approach to investigate the efficacy of written corrective feedback in second language (L2) writing instruction. With its widespread practice in second language acquisition (SLA), written corrective feedback has increasingly garnered attention as much as it has continued to be a subject of considerable…

The purpose of this meta-analytic review is to investigate the relation between statistical learning (SL) and language-related outcomes, and between SL and reading-related outcomes. A comprehensive search of peer-reviewed published research resulted in 42 articles with 53 independent samples and 201 reported effect sizes (Pearson's r). Results of…

Purpose: Narrative assessment is one potentially underutilized and inconsistent method speech-language pathologists may use when considering a diagnosis of developmental language disorder (DLD). However, narration research encompasses many varied methodologies. This systematic review and meta-analysis aimed to (1) investigate how various narrative…

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,"…

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,…

Purpose: This study examined the extent to which children born preterm (< 37 weeks) and/or who have low birth weight (< 2,500 g) catch up with their full term peers in terms of their language abilities at early school age (= 5 to < 9 years). Method: A systematic literature search identified empirical studies that fit the inclusion…

There is a general consensus that writing is a challenging task for students with learning disabilities (LD). To identify more precisely the extent and depth of the challenges that these students experience with writing, the authors conducted a meta-analysis comparing the writing performance of students with LD to their typically achieving peers.…

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…

Research on corrective feedback (CF), a central focus of second language acquisition (SLA), has increasingly examined how teachers employ CF in second language classrooms. Lyster and Ranta's (1997) seminal study identified six types of CF that teachers use in response to students' errors (recast, explicit correction, elicitation, clarification…

Despite the hundreds of Mobile-Assisted Language Learning (MALL) publications over the past twenty years, statistically reliable measures of learning outcomes are few and far between. In part, this is due to the fact that well over half of all MALL-related studies report no objectively quantifiable learning outcomes, either because they did not…

Factors, such as treatment complexity and duration, language proficiency, and educational context (EFL vs. ESL), can significantly influence language performance in experimental studies. The purpose of the present meta-analysis is to investigate the degree to which these causal factors influence linguistic improvement in studies of the English…

Mobile Assisted Language Learning (MALL) has emerged as a potential tool in the instruction of English as a foreign language (EFL). Meta-analysis of 13 studies published between year 2008 and 2015 was conducted. Four point criteria for the selection of studies for analysis is based on the year of publication, quasi-experimental design, pretest and…
