In second language (L2) vocabulary studies there is continuing interest in tests of depth of vocabulary knowledge, measuring various aspects of word knowledge other than just the form--meaning link that is the focus of breadth (or size) tests. This study aimed to explore new formats that could be used as diagnostic tools for assessing depth of…

In recent years, the integration of digital technologies into language learning has gained significant attention, particularly in the context of English as a Foreign Language (EFL) education. However, there remains a gap in understanding the broader affective and cognitive benefits of serious game-based learning (SGBL) in this field. The present…

This research examined the possibility of using Immersive Virtual Reality (IVR), Content and Language Integrated Learning (CLIL), and Total Physical Response (TPR) as a new method of teaching English as a Foreign Language (EFL) students. This study sought to explore the potential benefits of this integration of methodologies in order to facilitate…

Learning vocabulary is a central but yet complex aspect of learning a language. Hence, researchers stress the importance of facilitating vocabulary development via a structured approach to target words and recycling. While teaching materials have the potential to provide this structure to all students in a classroom, few studies have investigated…

Background: Generative artificial intelligence (GenAI) chatbots have shown great application potential and research value in the field of language learning, especially in second language acquisition (SLA). Objectives: This study aims to validate the value of GenAI chatbots for SLA and elucidate which moderating variables affect learning outcomes.…

Incidental vocabulary learning through reading may be influenced by a range of learner-internal as well as learner-external factors. This study, specifically, examined the potential impacts of three factors: text type, prior L2 vocabulary knowledge, and working memory capacity. Forty-six 1st grade high school students in Korea completed a battery…

This study investigated how a digital game-based learning (DGBL) environment affected low- (LP) and high-proficiency (HP) primary school students' self-regulated learning strategies and vocabulary development. Data were collected from 62 sixth graders (20 LP and 20 HP students) who learned English as a Foreign Language (EFL). The statistics…

Extensive evidence indicates that early vocabulary skills predict later reading development among monolingually developing children. Some evidence suggests that a relationship between vocabulary and later reading also holds across languages among children whose home language differs from the school language. However, these findings have been mixed…

Pop songs have been claimed to provide a noteworthy source of second language (L2) input. While listening to songs in English is one of the most commonly reported out-of-class activities among EFL learners, little research exists as to how different teaching approaches to the use of songs in the EFL class can enhance students' vocabulary learning.…

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…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

This article describes a new questionnaire, the "Diagnostic Inventory for Self-Regulated Language Learning" (DISLL), for assessing self-regulated learning strategies of students of English as an additional language. We discuss self-regulated learning models, evaluate existing questionnaires for assessing language learners' self-regulated…

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…

The writing system -- the transparency of orthography in alphabet-based systems and differences between logographic and phonetic-based systems -- can affect the efficiency of inferential word learning when words are introduced visually. It can also shape how people self-evaluate their learning success (we refer to such type of self-evaluation as…

Introduction: In the related literature, knowledge of vocabulary is mentioned to be crucial as one of the crucial parts of language learning. Measuring learners' vocabulary knowledge is regarded to be essential in that it provides both teachers and learners knowledge of the problematic areas and suggests some practical ways to improve the…
