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…

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…

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…

Vocabulary is an essential component of language learning. Despite the fact that form-focused instruction (hereinafter FFI) has been demonstrated to be effective in language learning, it remains unclear when and how FFI can contribute to vocabulary learning. To address this question, this study takes the timing of FFI into consideration and…

This study investigates the effects of combining blooket games with active learning to improve Chinese vocabulary memorization in first-year Chinese Language Teaching students at Rajabhat Mahasarakham University. This approach aimed to make learning more engaging for Thai students. The intervention involved 26 participants and vocabulary…

In this exploratory mixed-methods study, we introduce and test our AI-powered vocabulary learning system--ARCHe, which embeds four AI functions: (1) automatic feedback towards for pronunciation, (2) automatic feedback for towards handwriting, (3) automatic scoring for student-generated sentences and (4) automatic recommendations. Specifically, our…

Despite the substantial expansion in vocabulary research since the 1980s, we still know very little about how vocabulary develops over time and what factors influence this development. This methodological overview discusses key issues and considerations in vocabulary breadth growth assessment to help advance research in this area. The report…

Although research shows that second language (L2) learners have major difficulties in developing their productive vocabulary skills, little research has been conducted on how to facilitate productive mastery of learned words. With this in mind, this study investigated the effects of task type and repetition frequency on improving receptive word…

Traditional approaches to language assessment have been criticized for their inadequacy in taking account of language learners' potential for development. To obviate this pitfall in traditional assessment, language teachers and researchers have been paying increasing attention to dynamic assessment (DA), which is rooted in Vygotsky's (1978)…

This study explored the effects of listening-based lexical focus-on-form (lexical FonF) on the acquisition and retention of morphologically complex words. One hundred eighty-two adult English learners with two levels of English proficiency (higher and lower proficiency) from a public university in mainland China were assigned to three different…

This study investigated the effect of derivational suffix instruction on vocabulary knowledge. Fifty-eight high school learners were recruited to participate in the study. The learners were divided into control (n = 29) and experimental (n = 29) groups. The experimental group received a Fundamental English II course with an emphasis on…

Scheduling of practice to create a spacing effect has been observed to lead to superior retention of L2 vocabulary and grammar. Two of the various methods of scheduling L2 task practice discussed widely in recent times are interleaving and blocking. In a desirable difficulty framework, both of these methods have been recommended for task…

Purpose: There is evidence suggesting that aerobic exercise immediately after vocabulary training can improve word recall in school-age children. This work examined whether the previously identified word-learning benefits associated with exercise can be extended to preschoolers. Additionally, we evaluated whether the effects of physical activity…

Recently there has been some debate about the appropriacy of different lexical units in pedagogy and research (e.g., Brown et al., 2020; Dang & Webb, 2016a; Kremmel, 2016; Laufer & Cobb, 2020; McLean, 2018; Nation, 2016; Nation & Webb, 2011; Vilkaite-Lozdiene & Schmitt, 2020). The lexical unit (word types, lemmas, flemmas, word…

Working memory (WM) may be an essential component of incidental vocabulary learning and retention from captioned videos. However, how WM affects young learners' incidental vocabulary learning under different types of captions remains unclear. The present study employs a between-subject research design. The main purpose is to examine how two types…
