This paper presents a new method for accurately measuring the vocabulary size of second language (L2) learners. Traditional vocabulary size tests (VSTs) are limited in capturing a tester's vocabulary and are often population-specific. To overcome these issues, we propose an intelligent vocabulary size measurement method that utilizes massive robot…

Hu and Nation's (2000) study, which stipulated that second language (L2) readers need to be familiar with 98% of lexical items for adequate text comprehension, has become highly influential in L2 vocabulary research and pedagogy. However, the 98% critical threshold figure is based on findings from a research project in which a regression analysis…

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…

The thrust of this study was to investigate the impact of learning styles in general and Field dependence/Independence (FD/I) in particular on the receptive/productive lexical performance of language learners. It aimed to check whether FD/I learners perform differently on receptive and productive vocabulary tests. To achieve this, first, 94…

The present paper aims to investigate the interplay of lexical and grammatical development in school-aged Greek-Albanian bilingual children by providing evidence both from majority, Greek, and heritage, Albanian. To this end, 47 8 to 10-year-old bilingual children were tested by means of expressive vocabulary tests in Greek and in Albanian, while…

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…

Characteristics of vocabulary lists as well as study and test translation direction may affect the ease of learning second language (L2) vocabulary. We examined immediate and delayed test performance of first language (L1) English speakers learning a fixed set of L2 vocabulary placed on lists formed by crossing semantic relatedness (unrelated vs.…

This study investigates children's vocabulary knowledge in Finnish Sign Language (FinSL), specifically their understanding of different form-meaning mappings by using a multilayered assessment format originally developed for British Sign Language (BSL). The web-based BSL vocabulary test by Mann (2009) was adapted for FinSL following the steps…

This paper represents a summary and discussion of the three studies presented at the morning session of the Fall 2022 JALT Vocabulary SIG. The papers, which were written by Ali Al-Hoorie, Masaki Eguchi, Derek Canning, Stuart McLean, Christopher Nicklin, and Joseph Vitta, represent a range of topics and study designs that are common in recent…

The purpose of this paper is to (a) establish whether meaning recall and meaning recognition item formats test psychometrically distinct constructs of vocabulary knowledge which measure separate skills, and, if so, (b) determine whether each construct possesses unique properties predictive of L2 reading proficiency. Factor analyses and…

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…

Purpose: This study examined the effect of phonological overlap on English and Spanish expressive vocabulary accuracy as measured by the bilingual Expressive One-Word Picture Vocabulary Test--Fourth Edition (EOWPVT-IV). We hypothesized that if languages interact during an expressive vocabulary task, then higher phonological overlap will predict…

A cluster randomized design was used to investigate the effects of the "Story Friends" vocabulary curriculum on learning of 84 preschoolers in 24 classrooms who were at risk for language difficulties. Children in the treatment condition received explicit vocabulary instruction of 36 words during small-group storybook listening centers…

Extramural exposure, through activities such as watching TV, gaming, networking, and online reading, has become an important source of vocabulary acquisition in English as a foreign language, particularly when learners' first language (L1) has many cognates with English. Our study examined extramural vocabulary acquisition of 10th-grade L1…

Two commonly used test types to assess vocabulary knowledge for the purpose of reading are size and levels tests. This article first reviews several frequently stated purposes of such tests (e.g., materials selection, tracking vocabulary growth) and provides a reasoned argument for the precision needed to serve such purposes. Then three sources of…
