Language assessment is a central aspect not only of language education in the general population, but also amongst heterogeneous, low-incidence populations. One such population are immigrant deaf and hard-of-hearing learners (IDML) who are bimodal-multilingual and whose languages development often includes the spoken, written, and/or signed…

Background and Aims: The aim of the current study is to assess the validity of the Cross-linguistic lexical task (CLT) against direct and indirect measures of lexical skills across 2-6 years of age, for a crucial period of lexical development. In addition to evaluating relationships between measures at the level of total score, we also explored…

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…

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…

This study introduces the first Arabic Vocabulary Levels Test (Arabic-VLT), created for foreign learners of Arabic. We present compelling evidence to substantiate its validity and reliability. The Arabic-VLT was developed according to five levels, beginning with the most frequently used words (Level 1) to the least frequently used ones (Level 5),…

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…

Published work on vocabulary assessment has grown substantially in the last 10 years, but it is still somewhat outside the mainstream of the field. There has been a recent call for those developing vocabulary tests to apply professional standards to their work, especially in validating their instruments for specified purposes before releasing them…

The present study aims to bridge the gap of validating the Vocabulary Learning Strategies in Watching Audiovisual Materials (VLSWAM) questionnaire, a tool designed to assess strategies learners use to acquire vocabulary through audiovisual content. Grounded in multimedia learning theory, the study employed exploratory factor analysis (EFA) and…

The present study aimed to validate a 70-item Korean bilingual version of the Vocabulary Size Test (VST) using Rasch modeling. The goal was to assess the applicability of this Korean version of the VST for Korean learners of English in an English as a foreign language (EFL) context by examining validity evidence based on Messick's framework.…

Vocabulary assessment is an important part of measuring language proficiency in both monolingual and bilingual children. The LITMUS Cross-Linguistic Lexical Tasks (CLT) provides a framework for assessing the vocabulary of monolingual and bilingual children using a standardized procedure and comparable stimuli across languages. All language…

The objective of this study was to validate a bilingual Spanish-English version of the Vocabulary Size Test (VST) considering its potential use as a discriminator between learners in terms of language competence. This version was designed based on the two forms available on one of the creators' websites as well as considering practices recommended…

The purpose of this study is to determine whether a vocabulary size test is a valid and reliable measure of longitudinal growth in vocabulary size (VS), and to investigate the relationship between growth in VS and use of vocabulary learning strategies (VLS). Kasahara's (2006) revised version of Mochizuki's (1998) Vocabulary Size Test (VST) was…

Recent literature in the field of L2 vocabulary assessment has advocated for the development of written receptive vocabulary tests such as Vocabulary Levels Tests (VLTs) that use: (a) meaning-recall item formats, (b) a minimum of 40 item counts per 1,000-frequency band to improve level estimates, and (c) lemmas (not word-families) as the lexical…

Research Findings: The aim of this study was to construct and validate "English Picture Vocabulary Test (EPVT)" that aimed to assess the very young learners' (VYLs) receptive and expressive vocabulary knowledge for specific content areas in English as a foreign language (EFL). In this context, EPVT was created in several stages. One of…

An in-depth investigation of vocabulary depth knowledge by lexical researchers plays a prominent role in language learning and teaching. The objectives of the present study were to investigate the extent of relationship and prediction of the three constitutes of vocabulary depth knowledge (i.e., analytic relations, morphological knowledge, and…
