Objectives: The purpose of this article is to review research that has been conducted over the past five years on language development, reading skills and word learning with the use of the eye tracking machine as regards the population with autism spectrum disorder (ASD) in comparison to typically developed population. Materials and methods: A…

In Early Childhood Education and Care (ECEC) programs, the quality of teacher-child interactions is regarded to be important for children's vocabulary development. However, prior studies on the relationships between teacher and child, as measured by the Classroom Assessment Scoring System (CLASS), and children's vocabulary skills are inconsistent.…

As they develop into mature speakers of their native language, infants must not only learn words but also the sounds that make up those words. To do so, they must strike a balance between accepting speaker-dependent variation (e.g., mood, voice, accent) but appropriately rejecting variation when it (potentially) changes a word's meaning (e.g., cat…

This study set out to investigate the relationship between L2 vocabulary knowledge (VK) and second-language (L2) reading/listening comprehension. More than 100 individual studies were included in this meta-analysis, which generated 276 effect sizes from a sample of almost 21,000 learners. The current meta-analysis had several major findings.…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

This meta-analysis aimed to clarify the complex relationship between repetition and second language (L2) incidental vocabulary learning by meta-analyzing primary studies reporting correlation coefficients between the number of encounters and vocabulary learning. We synthesized and quantitatively analyzed 45 effect sizes from 26 studies (N = 1,918)…

We meta-analyzed the effectiveness of incidental second language word learning from spoken input. Our sample contained 105 effect sizes from 32 primary studies employing meaning-focused word-learning activities with 1,964 participants with typical cognitive functioning. The random-effects meta-analysis yielded a mean effect size of g = 1.05,…

The present article offers a review of the existing literature on L2 gains arising from participation in a study abroad (SA) experience. The purpose of this article is (1) to provide a general overview of research findings on the influence of time abroad on L2 development and (2) to identify the areas which need further research within the SA…

This meta-analysis reviewed research between 2012 and 2018 focused on technology-assisted second language (L2) vocabulary learning for English as a foreign language (EFL) learner. A total of 45 studies of 2,374 preschool-to-college EFL students contributed effect sizes to this meta-analysis. Compared with traditional instructional methods, the…

Although an abundant literature documents preliterate children's word learning success from shared storybook reading, a full synthesis of the factors which moderate these word learning effects has been largely neglected. This meta-analysis included 38 studies with 2,455 children, reflecting 110 effect sizes, investigating how reading styles, story…

Mobile devices are considered as the most widely used information and communication technologies. They have provided great advantages in language learning. This study reports a meta-analysis of the effectiveness of using mobile devices on vocabulary learning. A meta-analysis was conducted on research that compared the outcomes from students…

The present meta-analysis examined the overall average correlation (weighted for sample size and corrected for measurement error) between passage-level second language (L2) reading comprehension and 10 key reading component variables investigated in the research domain. Four high-evidence correlates (with 18 or more accumulated effect sizes: L2…

Results of a study are presented that suggest the grammatical structures of English some deaf and hard of hearing students struggle to acquire. A review of the literature from the past 40 years is presented, exploring particular lexical and morphosyntactic areas in which deaf and hard of hearing children have traditionally exhibited difficulty.…

This review of literature shows that how often a child is read to is related to subsequent gains in vocabulary. Not only do adults differ in the frequency with which they read to children (quantity), they also vary in reading style (quality). Several studies have proposed that the cognitive demand level of questions children are asked may be…

The issue of identifying reading difficulties and disabilities in English language learners (ELLs) is a complex one. It is an area that draws on the diverse disciplines of first- and second-language acquisition, literacy, English language learning, and reading, including differences and disabilities research. This literature review aims to…
