This study investigates the acoustic realizations of English phonemic contrasts by Korean EFL learners, comparing their productions with those of native English speakers. Focusing on the segmentally correct production, the research aims to determine if Korean learners' acoustic properties align with those of native speakers, influenced by second…

University classrooms are increasingly populated by students with diverse nationalities and native languages (L1). The growing number of students in English-led classrooms who speak English as a second or lower language (L2) may face added difficulties in understanding the specific task objectives or directions, as explained by native-…

This study explored the relative effect of recasts on second language (L2) Korean learners' accuracy development of the object relative clauses (RCs) and the honorific subject-verb (S-V) agreement in Korean and its relationship with language analytic ability (LAA). Forty-five L2 Korean learners participated in the study and five Korean native…

The present study investigated Korean-accented English (KoE) intelligibility and conducted experiments in Korea, Japan, and the USA to test the benefits of listener's familiarity and identify the key phonological features of KoE. In the experiments, the participants were asked to transcribe the target (KoE) of 100 English statements each…

Recent research conducted as part of the English Profile identified grammatical criterial features that are characteristic of each Common European Framework of Reference (CEFR) proficiency level. The extent to which these criterial features attest in English learners of various first language backgrounds call for an empirical examination. In this…

This study investigates the effects that three different test presentation formats, i.e., written Korean, written English and aural English, have on EFL learners' listening comprehension. A total of 169 Korean college students participated in this study. The participants were divided into six groups, by three presentation format types and two…

By adopting a usage-based approach to language acquisition, this study investigated the emergence and development of L2 constructional knowledge. A total of 19 English verb-argument constructions (VACs) and their associated verbs were extracted from a learner corpus and three verbal fluency tasks, each conducted in L1 and L2 English and L1 Korean.…

This study investigated the most effective way to present an instructional video that contains words in the students' second language. Korean-speaking university students received a 16-min video lesson on Antarctica that included English narration (video + narration group), English text subtitles (video + text group), or English narration with…

(1999). "Childhood bilingualism and metalinguistic skills: Analysis and control in young Swedish-English bilinguals."…

The present research study investigated the effects of 8 versions of a computer-based vocabulary learning program on receptive and productive knowledge levels of college students. The participants were 106 male and 103 female Korean EFL students from Kyungsung University and Kwandong University in Korea. Students who participated in versions of…

Within the input and interaction research paradigm, how learners' individual differences play a role in using learning opportunities during interaction has become one of the main areas of investigation. Recasts have also received much attention in interaction research. This paper explores the extent to which individual differences in grammatical…

A promising source of insights into heritage language learning comes from the broader study of the role of input in language acquisition. We concentrate here on the possibility that qualitative differences in the proficiency of heritage and monolingual language learners can be traced to a qualitative difference in the input available to each…

Placing heritage Speakers into Korean language classes is a challenging task because they display a wide range of proficiencies.
