Background: Foundation Phase teachers in the South African Department of Basic Education system daily encounter a challenge with learners struggling to read with understanding. This motive was displayed and made available to readers and authors by the recent Progress in International Reading Literacy 2021, which articulated that learners in the…

Research syntheses that evaluate bilingual program effectiveness have grown exponentially since the 1980s. Contradictory to earlier anti-bilingual findings, these research syntheses, including statistical meta-analyses, have converged on findings supporting L1 teaching. This study examines the methodological soundness of eight statistical…

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…

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…

This meta-analysis synthesized the effects of the English medium instruction and content and language integrated learning (EMI-CLIL) approach on secondary-level students' English learning. The dataset included 44 samples (N = 7,434) from 38 primary studies. The results revealed EMI-CLIL's overall effectiveness for the development of English…

This study aims at drawing a conclusion about the use of the first language (L1) in language classes on which there is still no consensus among researchers. In line with this aim, the qualitative studies involving participants' views or practices obtained through interviews or observations were analyzed and then synthesized. Firstly, two basic…

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…

This meta-analysis examines how components of the Simple View of Writing contribute to writing development for English second-language (L2) learners. Previous studies examining first-language learners suggest that transcription and ideation may predict writing achievement. In order to investigate whether these components similarly contribute to L2…

This meta-analysis investigated the overall effects of glossing on L2 vocabulary learning from reading and the influence of potential moderator variables: gloss format (type, language, mode) and text and learner characteristics. A total of 359 effect sizes from 42 studies (N = 3802) meeting the inclusion criteria were meta-analyzed. The results…

Oral language skills underpin children's educational success and enhance positive life outcomes. Yet, significant numbers of children struggle to develop competence in speaking and listening, especially those from areas of high economic deprivation. A tiered intervention model, graduating the level of provision in line with levels of need, has…

Past experimental studies of corrective feedback (CF) have isolated factors like grammatical complexity, learner proficiency, and L1 one by one, carefully designing experiments that eliminate the influence of "extraneous" factors. Because each factor is actually codependent, more holistic study is needed. Eleven studies, all of which had…

Children who are dual language learners (DLLs) often have more difficulty acquiring English early literacy skills than their English monolingual peers. Much remains to be learned about efficacious early literacy instructional interventions and their effects on English early literacy skills of DLLs. The purposes of this systematic review were to…

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…

The effectiveness of bilingual programs for promoting academic achievement of language minority children in the United States has been examined in six meta-analyses. The present meta-analytic study investigates this topic for the first time in the European context. Thorough literature searches uncovered 101 European studies, with only 7 meeting…
