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…

Vocabulary and grammar are crucial to language proficiency. Certain word families and grammatical categories are differentiated by prosodic features like suprafixes. In English, specific noun/adjective-verb pairs, often called disyllabic words, have primary stress on different syllables: nouns usually receive trochaic stress, while verbs receive…

This study aims to evaluate the extent to which Taylor Swift's song lyrics incorporate vocabulary from the Oxford 3000 and 5000 word lists and to categorize these words based on CEFR levels. The goal is to narrow down the vast selection of songs available to EFL learners, focusing on the most essential vocabulary to enhance their learning…

This study investigates the effects of multilingualism and the degree of proficiency in different languages on vocabulary knowledge among Spanish language learners. Participants completed a 160-word meaning recall test designed to measure their knowledge of the 8,000 most frequent Spanish words and a self-assessment questionnaire on their…

Neural Machine Translation (NMT) has gained increasing popularity among EFL learners as a CALL tool to improve vocabulary, and many learners have reported its helpfulness for vocabulary learning. However, while there has been some evidence suggesting NMT's facilitative role in improving learners' writing on the lexical level, no study has examined…

Vocabulary proficiency diagnosis plays an important role in the field of language learning, which aims to identify the level of vocabulary knowledge of a learner through his or her learning process periodically, and can be used to provide personalized materials and feedback in language-learning applications. Traditional approaches are widely…

Research confirms that critical thinking plays a fundamental role in decision making and problem solving, skills that are essential to function as successful adults in a complex world. Consequently, it has been a focus of educational research for decades. Faculty meetings and teacher training sessions repeatedly run sessions on ways that teachers…

Since its emergence, generative AI has significantly impacted various fields, including English language education. Numerous academic studies have investigated its capabilities in grammar correction, writing evaluation, and dynamics of user interaction. However, there have been insufficient investigations into whether texts generated by such AI…

The 2025 Central States Conference on the Teaching of Foreign Languages was held in Kansas City, Missouri on March 13-15. This year's theme, "Global Goals, Global Languages," highlighted the partnership of the United Nations' 17 Sustainable Development Goals (Global Goals) and language curricula. The Global Goals were created to address…

Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor…

This volume presents research on second language learning through audiovisual input, conducted within the SUBTiLL (Subtitles in Language Learning) project at the University of Barcelona. It includes studies exploring various language dimensions and skills, such as vocabulary, pronunciation, and reading, while also considering learner factors, such…

Extensive Reading (ER) emerges as a promising approach for acquiring a foreign language, allowing for a large amount of language exposure. However, the influence of supplementary activities within ER programs has yet to be thoroughly investigated, despite previous studies suggesting their potential effectiveness. This research investigated the…

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.…

Studies on graded readers used in extensive reading have tended to focus on vocabulary. This study set out to investigate the linguistic profile of graded readers, taking into account both grammar and lexis. A corpus of 90 readers were tagged according to the variables in Biber's Multidimensional (MD) analysis, using the Multidimensional Analysis…

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…
