This longitudinal study examined how receptive and expressive vocabulary assessments capture vocabulary development in children with Autism Spectrum Disorder (ASD) and typically developing (TD) children. Using mixed regression modelling, we explored when children with ASD significantly different from TD children. We also examined the variability…

Vocabulary knowledge plays an important role in language learning and language proficiency, but it is difficult to know how much of a role it plays without appropriate vocabulary measures. In this article, we first discuss learner vocabulary in our research on Korean as a second/foreign language. Unable to find appropriate measures for receptive…

Children's early language development is under the influence of several positive and negative factors including television as an input source and family's socio-economic status. Considering that, this study investigated the effects of these variables on children's vocabulary development using a quasi-experimental design. To this end, 60 Iranian…

A large number of children are exposed to more than one language. One well-established method of assessing early vocabulary development in monolingual children is parent report; however, its use in bilingual/multilingual contexts is less established and brings unique challenges. In this methodological scoping review, we reviewed studies of early…

Children's early understanding of mathematics provides a foundation for later success in school. Identifying ways to enhance mathematical instruction is crucial to understanding the ideal ways to promote academic success. Previous work has identified mathematical language (i.e., the words and concepts related to early mathematical development such…

Multimedia glosses have been examined extensively by researchers for over three decades to determine their possible effects in second language (L2) vocabulary acquisition. Many meta-analytic studies aimed to determine the extent to which glosses can impact L2 vocabulary learning and the moderators that can mediate the results of meta-analytic…

There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during…

Background: Vocabulary scores increase until approximately age 65 years and then remain stable or decrease slightly, unlike scores on tests of other cognitive abilities that decline significantly with age. Aims: To review the findings on ageing-related changes in vocabulary, and to discuss four methodological issues: research design; test type;…

Vocabulary learning strategies have been frequently viewed as a practical tool to facilitate the acquisition of words and enhance comprehension and production in communication. Previous research suggests that vocabulary learning strategies are a multidimensional construct. This study attempts to validate a vocabulary learning strategies…

It remains unclear whether pragmatic language skills and core language skills (grammar and vocabulary) are distinct language domains. The present work aimed to tease apart these domains using a novel online assessment battery administered to almost 400 children aged 7 to 13 years. Confirmatory factor analysis indicated that pragmatic and core…

Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

The current study reported an empirical investigation that tested the collective and individual effects of morphological awareness and cognate awareness on Japanese word learning among Chinese learners of Japanese. 131 Chinese learners of Japanese participated in this study. They completed morphological awareness measurements (morpheme…

The issues of depth vocabulary knowledge and Willingness to Communicate (henceforth, WTC) are among the most important issues in second language learning. The present study set out to empirically look into the contribution of WTC to depth of vocabulary knowledge in L2 learning. To this end, 88 English L2 learners, divided into two groups in terms…

This study addressed a gap in existing research on Multiple-Choice (MC) cloze tests by focusing on the learners' perspective, specifically examining the difficulties faced by vocational high school students (VHSs). A nationwide sample of 293 VHSs participated, providing both quantitative and qualitative data through a self-developed questionnaire.…

In language and second language acquisition research, it is important to have a measure for tracking the proficiency level of participants. Lexical competence is fundamental for communicative purposes in a given language, and vocabulary tests are a reliable measure to assess lexical proficiency. That is why vocabulary tests have a central role in…
