This study explores the complex relationships between language learning motivation, vocabulary learning strategies, and two components of second language vocabulary knowledge (i.e., vocabulary size and depth), within the framework of self-regulated learning. Responses to questionnaires were gathered from 185 secondary-level Korean adolescent…

With the growth of chatbots, concerns about implementing artificial intelligence (AI) chatbots in educational settings have consistently arisen, especially for the purpose of language learning. This study introduced a task-based voice chatbot called "Ellie", newly developed by the researchers, and examined the appropriateness of its task…

This meta-analysis synthesized the effects of the English medium instruction and content and language integrated learning (EMI-CLIL) approach on secondary-level students' English learning. The dataset included 44 samples (N = 7,434) from 38 primary studies. The results revealed EMI-CLIL's overall effectiveness for the development of English…

The purpose of this article is to set out the design principles and architecture of a second language (L2) learning voice chatbot. Building on L2 acquisition theories and chatbot research, in this article, we report on a South Korean government-funded longitudinal project in which we designed and developed a chatbot called "Ellie".…

In this study, we used a data-mining approach to identify hidden groups in a corpus-based second-language (L2) vocabulary experiment. After a vocabulary pre-test, a total of 132 participants performed three online reading tasks (in random orders) equipped with the following glossary types: (1) concordance lines and definitions of target lexical…

The purpose of this study was to investigate the value of introducing digital storytelling (DST) into second language (L2) narrative practice, by examining the characteristics of L2 learners' narrative when multimodality is added. To this end, the present study examined pairs of personal narrative scripts produced by 50 undergraduate L2 learners…

This article introduces the structure and content of an online learning platform called "SMART Teacher Lab" (STL, henceforth) implemented at the authors' university since 2014. "STL" is an online platform specifically built for the professional development of pre- and in-service English as a Foreign Language (EFL) teachers,…

The present study examined the interaction effects between teachers' choice of language in lexical explanation and second language (L2) learners' proficiency level on the learning of phrasal verbs and listening comprehension in a meaning-focused listening activity. Undergraduate L2 learners with two different levels of proficiency (intermediate…

This study examines the relative effects of teacher code-switching and English-only instruction on the vocabulary learning of EFL preschoolers (age 5 and 6), along with their attitudes towards language choices in English learning. Seventy-two young EFL learners were engaged in storytelling activities, either in code-switching or English-only…

The present article deals with the issue of how to create and operate a customizable on-line concordancer from viewpoints of language teachers and with their own laptops. It aims to introduce how to use and manage this application without relying on computer engineers for various pedagogical purposes, focusing on the four beneficial dimensions of…

Despite the increasing volume of studies on classroom language use research, scant attention has been paid to the relationship between learners' attitudes towards classroom language choice and classroom variables that they perceive to motivate their target language learning. This study examines this issue with Korean undergraduate English as a…

The present study was designed to examine the effects of short-term study abroad (SA) on learners' L2 anxiety, international posture, and L2 willingness to communicate (WTC). To this end, the SA experience of 69 L2 learners in four different SA programmes was investigated. The data were obtained from participant questionnaires, which were…

The present study investigates the effects of two different vocabulary learning conditions in digital reading environments equipped with electronic textual glossing. The first condition presents the concordance lines of a target lexical item, thereby making learners infer its meaning by reading the referenced sentences. The second condition…

The non-native English-speaking teachers' (NNESTs) beliefs about the monolingual approach have not been sufficiently studied in the teaching of English as a foreign language (EFL). In examining the NNESTs' beliefs about that issue, the present study adapts Guy Cook's recent framework, according to which the monolingual approach is based upon four…

This paper concerns the conceptual and pedagogical issues that revolve around target language (TL) only instruction and teacher code-switching in the context of TL classrooms. To this end, I first examine four intertwined ideas (that is, monolingualism, naturalism, native-speakerism, and absolutism) that run through the monolingual approach to TL…
