Abundant research has indicated fluency features as meaningful predictors of second language proficiency. However, the extent to which different fluency dimensions and features can predict proficiency remains underexplored. This meta-analysis employed a multilevel modeling approach to synthesize fluency-proficiency relationships from 71 empirical…

Purpose: Phonetic training has been found to be an effective way on second language (L2) learning, but the evidence is not conclusive regarding the effectiveness of different instructional approaches and possible interactions between language learners, training features, and outcome measures. This study aims to meta-analyze existing studies to…

This meta-analysis included 27 empirical studies to explore the effectiveness of robot-assisted language learning (RALL) as well as the moderating effects of a number of variables. The comparison of 64 effect sizes from 2,637 participants indicated significant variability between the independent samples. The overall results showed that the…

This study explores the correlation between technology utilization and language acquisition while analyzing the impact of moderating variables on this relation. Our meta-analysis approach analyzes data from 43 extracts out of 19 primary studies published between 2012 and 2021. Our data analysis employs a random-effect model utilizing a…

Due to their experience of managing two languages, it has been suggested that bilinguals could receive more practice in the domain of working memory (WM) leading to a WM bilingual advantage. Although some studies have shown that bilinguals can outperform monolinguals in WM tasks, the studies investigating WM capacity in bilinguals provide…

High-Variability Phonetic Training (HVPT) has demonstrated effectiveness in second language (L2) acquisition. This study utilizes a meta-analysis to explore the influence of high variability on learning L2 pronunciation and identifies the factors that moderate this impact. The studies were collected using a keyword search in the SCOPUS database.…

Becoming one of six official United Nations languages, English proficiency has become a prominent requirement for students and professionals entering international education and/ or careers, as assessed through standardized English proficiency tests. English learners conducted varied procedures to pursue the minimum test score criteria, including…

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)…

The increasing integration of artificial intelligence (AI) in education has raised significant questions about its pedagogical value, especially in language learning. This meta-analysis examines the extent to which AI contributes to the development of English-speaking and listening skills. A systematic review of the literature was conducted by the…

An increasing number of students complete an internship during their higher education studies in a country different from that of their home institution. A main advantage of this type of mobility is that it responds to employers' need for graduates with both hands-on experience and global skills. In this paper, we attempt to review existing…

Previous meta-analyses of reading strategy (RS) instruction in second and foreign language (L2) contexts have consistently shown that RS instruction has a positive impact on reading comprehension. However, whether RS instruction can promote both the use of RS "and" reading comprehension among English L2 learners is unclear. The effect of…

Elicited imitation tasks (EITs) have been proposed and examined as a practical measure of second language (L2) proficiency. This study aimed to provide an updated and comprehensive view of the relationship between EITs and other proficiency measures. Toward that end, 46 reports were retrieved contributing 60 independent effect sizes (Pearson's r)…

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…

The main purpose of this study is to investigate the best approaches to teaching a foreign language to older people to help them achieve the desired results and explore their benefits. This review strictly follows the PRISMA methodology for systematic reviews and meta-analyses to identify the core experimental studies that deal with the topic of…

The aim of this study is to comprehensively evaluate quantitative experimental mobile-assisted language learning (MALL) studies published between 1994 and 2019 that meet minimal conditions of research design and statistical analysis. Starting with a bibliographical database of 1,144 references to experimental MALL implementations, of which there…
