Studies into the role of audiovisual input and captions (i.e., subtitles in the same language as the audio) for L2 learning have shown that such input can positively influence L2 learners' acquisition of lexical items. Few studies have explored the effects of captioning on learners' capacity to segment the speech stream. This study investigates…

This study investigated English learner profiles and challenges among 884 Korean 5th-grade students, with a focus on the role of AI-assisted language learning in shaping proficiency outcomes. While AI-based interventions have gained popularity, their effectiveness across diverse learner populations remains insufficiently explored. The study aimed…

The use of AI-powered chatbots has recently been extensively examined for second language (L2) learning. While their positive effects have been widely reported regarding L2 English learning, studies involving less commonly taught languages (LCTLs) are scant. The current study incorporated an AI chatbot called Iruda in L2 Korean teaching, to…

This study examined how unimodal and bimodal learning conditions impact L2 vocabulary processing and learning, comparing reading only (RO) and reading while listening (RWL) groups. 119 high intermediate-advanced English learners read or read-while-listening a short story embedded with 25 target pseudowords, repeated 10 times each, and had their…

There is currently limited investigation of readers' comprehension of AI simplified text from the perspective of educators, but such research can help to more effectively address the specific needs and perspectives of language teachers and learners regarding the comprehensibility of AI simplified text. Therefore, the purpose of this study was to…

Metacognitive knowledge, closely correlated with one's writing skills, has received increasing research and pedagogical attention. Applying Flavell's metacognition framework, this study adopts a quasiexperimental design to investigate whether and how a DMC assignment as a pedagogical intervention influences Chinese English as a Foreign Language…

While previous investigations on online machine translation (MT) in language learning have analyzed how second language (L2) learners use and post-edit MT output, no study as of yet has investigated how the learners process MT errors and what factors affect this process using response and reading times. The present study thus investigates L2…

Given the accumulating evidence about audiovisual input as a valuable resource from which knowledge of multiword expressions (MWEs) can be built up incidentally, the next inquiry arises as to what can be done to promote MWE uptake from this resource. Despite the increasing popularity of bilingual subtitles as a form of on-screen text, their…

Multimodal synchronous-computer-mediated communication (SCMC) provides many possibilities for improving language learners' pragmatic competence (Maa & Taguchi, 2022). However, the research exploring how SCMC mode affects the pragmatic learning process and its outcome is limited. This study investigates the effects of SCMC modes on pragmatic…

How online interactants advance their talk in written interactions has been extensively investigated in different areas, including language learning. Applying a conversation analysis technique, this study examined how second language (L2) learners managed topics in L2 task-based text-chat interactions and the effects of L2 proficiency on their…

Although digital game-based vocabulary learning (DGBVL) has received increasing attention in the past two decades, the impacts of DGBVL on the depth of word knowledge are still not well understood, especially in regard to productive vocabulary learning and DGBVL's long-term efficacy. This study leverages a quasiexperimental research design to…

Speaking in a foreign/second language is a challenge for many learners, even when they have linguistic knowledge. Drawing on González-Lloret and Ortega's (2014) framework for technology-mediated tasks and MacIntyre's (2007) framework for willingness to communicate in a second language, this mixed methods study investigated the impact of…

Language learners around the world are increasingly using applications (apps) to learn second/foreign languages (L2). However, research on the effectiveness of these apps for developing general language proficiency, particularly compared to classroom-based instruction, is still limited. This study examined the L2-English proficiency and lexical…

Empirical evidence remains sparse about how videos enhanced with first-language (L1) and second-language (L2) subtitles influence cognitive load in L2 learners. To address this point, 25 Korean undergraduate students were exposed to six short videos: baseline, L1-subtitled, and L2-subtitled videos at both high and low difficulty levels (determined…

This study examines the potential of ChatGPT to enhance grammar development in an academic writing context, where grammar instruction is often overlooked. Adopting a qualitative case study, this research explores how a localized version of ChatGPT can assist first-year undergraduate students in improving their grammar in writing tasks. The study…
