This paper presents data capturing Korean university students' familiarity with English online acronyms, examines factors that may predict this familiarity, and presents an explicit instruction intervention involving vocabulary knowledge of online acronyms. The Vocabulary Size Test (VST) measured students' vocabulary size, while a self-report…

This study explored how teachers could provide support to enhance students' out-ofclass mobile-assisted language learning (MALL) engagement. We interviewed five Korean English teachers who used "Class Card," a focal technology of this study, for their students' self-directed vocabulary learning. Additionally, students of the interviewed…

This study investigated the effects of multisensory memory strategies of pairing visual and aural learning strategies of aural lexical advance organizers (LAO) and read-alouds on 146 Korean high school students learning the meaning and pronunciation of 18 unfamiliar English words. In this quasi-experimental design, the control group learned 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.…

This paper investigates the cognitive processes involved in English word recognition among young EFL learners using eye-tracking methodology. A quasi-experimental mixed method design was used to investigate how young L2 learners engage with basic words, with or without pictorial cues. A total of seventeen 6th-grade pupils from two schools…

Using vocabulary learning strategies allows learners to gain vocabulary autonomously. This study presents data from a self-report survey of Korean university students comparing meaning discovery strategies they employ to comprehend unknown singleword items and unknown idioms. Survey data recorded strategies used by learners, and effectiveness of…

This study investigated the effects of processing three types of texts, namely expository texts, narrative texts, and a combination of both known as twin texts, on incidental vocabulary acquisition and retention in L2 learners. College freshmen (N = 109), who were lower to upper intermediate learners of English, were assigned into a control group…

This study investigated the effects of exposure frequency, depth of processing, and activity repetition types on vocabulary learning. In total, 78 South Korean fifth-grade students were divided into four conditions. Students in each condition were asked to read a passage with four of the eight target words (exposure: four times) and the other four…

Research suggests that prediction is important for language comprehension and learning. Accordingly, it becomes crucial to understand factors that can influence prediction. In this regard, speakers' prior linguistic experience such as parsing bias has been claimed to affect prediction in the error-based learning account. To test this claim, the…

The present study aimed at investigating the effectiveness of bottom-up (BU) and top-down (TD) approaches on EFL learners' vocabulary learning, the difference in the effects of the two approaches depending upon their level of vocabulary proficiency, and their perception of the approaches. For this study, 122 college students were divided into two…

Few dictionary studies have examined the effectiveness of freely available online dictionaries (FAOD) offered by search engine companies. This experimental study examines the effectiveness of one FAOD, Naver.com, as an aid to vocabulary acquisition for a group of 87 intermediate-level Korean university students aged 19 to 28 (mean 21.9). The VKS…

The use of language learning strategies has been linked to effective EFL learning. However, while some researchers have suggested that good language learners use more strategies and more sophisticated strategies than less successful learners, others have disputed the unconditional nature of this view with the suggestion that factors such as task…

This paper examined the use of assessment techniques in extensive reading and students' and teachers' perceptions on the practice of extensive reading. A total of 232 university students who were placed at different proficiency levels of classes and 13 professors participated in the study by completing a questionnaire. In-depth interviews were…

This study compares the results of a survey of vocabulary learning strategy (VLS) use and perceived helpfulness by Korean university students to the taxonomy of VLS first presented by Schmitt. VLS suggested by previous research by the author and changes in technology since the original taxonomy was compiled were added to Schmitt's list. The survey…

The present study aims to investigate the direct and indirect contributions of Korean EFL college students' L2 receptive and productive vocabulary knowledge to their L2 writing performances by using a structural equation modeling (SEM) analysis with a goal to explore the pathways of vocabulary knowledge to writing. Data from 178 students were…
