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…

Second language (L2) viewing with captions (i.e., L2 on-screen text) is now a proliferating as well as promising area of L2 acquisition research. The goal of the present meta-analysis was to examine (a) the relationship between captioned viewing and incidental vocabulary learning and (b) what variables related to learners, treatment, methodology,…

The Production-oriented Approach (POA) is an emerging language teaching method tailored to the characteristics of Chinese learners, but the existing experimental studies have yielded inconsistent results. Therefore, this study employs a comprehensive meta-analysis to assess the overall effectiveness of POA on students' English language skills, and…

Background: English second language (ESL) and English foreign language (EFL) vocabulary learning play a vital role in success in higher education. However, traditional vocabulary learning methods can be time-consuming, demotivating, and ineffective. Recent technological developments offer engaging and immersive methods for vocabulary learning,…

Test preparation has garnered considerable attention in second language (L2) education due to the significant implications that successful performance on a language test may have for academic advancement, future career opportunities, and immigration prospects. Meanwhile, an overemphasis on test preparation has been criticized for encouraging the…

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…

In this meta-analysis, we examined the average correlations (weighted for sample size and corrected for measurement error) between the varied types of motivation specified within self-determination theory (SDT) and second language (L2) achievement. We also conducted moderator analyses to explore whether these relationships are influenced by age,…

Transparency in assessments means ensuring their validity, reliability and authenticity. While it remains limited in practice when administering internationally validated literacy assessment tools, one major factor necessitates transparently reporting achievement results in light of learners' linguistic repertoires. Sitting these literacy…

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…

The rise of informal language learning, especially learning conducted online outside the classroom context, has received considerable scholarly attention in recent years. To date, however, there has been limited evidence-based systematic analysis of the prevalence of online informal language learning (OILL). Accordingly, we conducted a systematic…

Purpose: This meta-analysis study aimed to determine the optimal level of talker variability in training to maximize second-language speech learning. Method: We conducted a systematic search for studies comparing different levels of talker variability in nonnative speech training, published through July 2024. Two independent reviewers screened…

The 21st century requires English language teaching teachers to cultivate the use of language and competencies to make their students 21st-century learners. Podcasts produced by students allow them to use language in an authentic setting while practicing the skills of critical thinking, innovation, creativity, problem-solving, reflection, and…

Studies remain controversial concerning how enjoyment, anxiety, and boredom relate to foreign language learning (FLL) achievement. There is an inadequacy of synthesis of factors addressing the debate on emotion correlations in the empirical results. Underpinned by the control-value theory (CVT) of achievement emotions, a meta-analysis is conducted…

Research on the effects of second language (L2) listening strategy instruction (SI) has gained momentum in recent years (e.g. Vandergrift & Tafaghodtari, 2010). However, the reported results have been inconclusive and varied across studies. Synthesizing the results of quantitative research in this domain, the present meta-analysis sought to…

The purpose of the present study was to analyze the impact of technology on student foreign language learning, as it has been widely used to enhance language instruction over the past few decades. This multivariate meta--meta-analysis study aimed to examine the effects of technology on various aspects of language learning, including listening,…
