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…

Despite the growing interest in incorporating textual glosses into second language (L2) reading in hypermedia and paper media, no agreements have been reached as to whether and what extent a textual gloss facilitates L2 learners' vocabulary acquisition in hypermedia and paper media. The present study meta-analysed the overall effects of textual…

There has been increasing interest in the effects of note taking in second language (L2) research. However, no meta-analysis has been conducted to examine the relationship between note taking and learning through exposure to L2 input. We retrieved 28 effect sizes from 21 studies (N = 1992) to explore the overall effects of note taking as well as…

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,…

Second language (L2) learners' beliefs about the nature of language learning, specifically language mindsets, is a recent productive line of L2 research. Researchers argue that language mindsets are key factors for language learning success. However, the association between language mindsets and different language learning outcomes is inconsistent…

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 systematic review addressed the following question: Which are the relations between L1 and/or L2 foundational and upper-level language skills, cognitive skills, high-order cognitive and self-regulation factors and L2-English reading comprehension skills in 11-to-19 year EFL secondary school students with different L1 language profiles?…

The use of automated writing evaluation (AWE) in second language (L2) writing contexts has increased dramatically, as evidenced by the large body of research published on the topic over the past decade. Considering this, several systematic reviews on AWE have been published. Nevertheless, none of these review studies has exclusively focused on the…

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…
