Meta-analytic studies of second language (L2) learning typically employ a classic approach to meta-analysis. Although the classic approach can clarify findings, a multivariate, multilevel meta-analysis (3M) approach increases transparency by accounting for (a) dependencies in the evidence presented by primary studies, (b) methodological…

This meta-analysis includes experimental and quasi-experimental studies of reading interventions for English learners (ELs) coupled with four specific instructional strategies. The purposes of this meta-analysis were two-fold: (1) to identify the effects of the four instructional strategies (i.e. scaffolding, graphic organizers, interactive read…

While numerous studies of robot-assisted language learning (RALL) for English-as-a-foreign-language (EFL) learners' language skill development have been done, a comprehensive and theoretically-driven meta-analysis on its effects is still in paucity. To fill the gap, drawing on Activity Theory (AT), this study reported a meta-analysis from 47…

In today's interconnected world, cross-cultural competence is essential for students' success. This article investigates how educational interventions foster this crucial skill. Using a mixed-meta research method, the study combines a meta-analysis of 16 quantitative studies (12,800 participants) with a meta-thematic analysis of 7 qualitative…

Purpose: Despite numerous studies reporting beneficial effects of metacognition for improving learning or developing self-regulated learners, the evidence from tertiary English as a Foreign Language (EFL) settings is still unclear as synthesis studies in this field remain rare. To address the gap, this study sought to identify, examine and…

This study meta-analyzed the last four decades (1980-2020) of reading intervention research focused on improving reading outcomes for English language (EL) students in Grades K-5 with or at risk for word reading difficulties. Experimental and quasi-experimental group design and single-case experimental design (SCED) studies were included; 10 group…

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…

To address the evidence gap in making effective language of instruction (LOI) decisions, we propose a systematic review of the role of LOI choices in education programs and policies on literacy outcomes in multilingual educational contexts in low- and middle-income countries (LMICs). Grounded in a multidisciplinary theory of change (ToC)…

Ongoing debate exists concerning pedagogical strategies including song to improve vocabulary learning in second or foreign language learners. A search of primary empirical studies published from 1990 to 2020 produced 27 articles with 28 studies and 1864 total participants. Effect sizes were analysed for the influence of English instructional…

Despite accumulated evidence demonstrating the effectiveness of flipped language classrooms in higher education, there is no quantitative examination of the extant empirical studies to draw a general conclusion. Based on Bayesian methodologies and 26 effect sizes, this study quantitatively examines empirical studies that investigated flipped…

Despite considerable efforts made to understand the impact that instructional interventions have upon L2 reading development, we still lack a clear picture of the influence that PA and phonics instruction has upon reading in English as an L2. A search of the research literature published from 1990 to 2019 yielded 45 articles with 46 studies…

Despite the growing body of research regarding the effectiveness of MALL (mobile-assisted language learning) technologies on foreign language (FL) learners' speaking skill development, a comprehensively quantitative meta-analysis regarding the effect sizes of these studies is still lacking. To solve the problem, this study reported results based…

Automated writing evaluation (AWE) has been frequently used to provide feedback on student writing. Many empirical studies have examined the effectiveness of AWE on writing quality, but the results were inconclusive. Thus, the magnitude of AWE's overall effect and factors influencing its effectiveness across studies remained unclear. This study…

A meta-analysis was conducted in this study to synthesize research on technology-enhanced language learning published from 1990 to 2015. The purpose of this meta-analytic review was twofold, namely to investigate the effectiveness of improving students' second language acquisition with the assistance of technology, and to identify variables that…

This meta-analysis synthesized research on math performance outcomes for English learners (EL) as a function of language-focused (math vocabulary) interventions. We included group and single-subject design studies with children from kindergarten to 8th grade (3,766 students for group, 30 for single-subject). Group studies yielded a mean Hedges' g…
