  • Recent studies have shown that the stop system of Korean is undergoing a sound change in terms of the two acoustic parameters, voice onset time (VOT) and fundamental frequency (f0). Because of a VOT merger of a consonantal opposition and onset-f0 interaction, the relative importance of the two parameters has been changing in Korean where f0 is a primary cue and VOT is a secondary cue in distinguishing lax from aspirated stops in speech production as well as perception. In English, however, VOT is a primary cue and f0 is a secondary cue in contrasting voiced and voiceless stops. This study examines how Korean English learners use the two acoustic parameters of L1 in producing L2 English stops and whether the sound change of acoustic parameters in L1 affects L2 speech production. The data were collected from six adult Korean English learners. Results show that Korean English learners use not only VOT but also f0 to contrast L2 voiced and voiceless stops. However, unlike VOT variations among speakers, the magnitude effect of onset consonants on f0 in L2 English was steady and robust, indicating that f0 also plays an important role in contrasting the [voice] contrast in L2 English. The results suggest that the important role of f0 in contrasting lax and aspirated stops in L1 Korean is transferred to the contrast of voiced and voiceless stops in L2 English. The results imply that, for Korean English learners, f0 rather than VOT will play an important perceptual cue in contrasting voiced and voiceless stops in L2 English.

  • Purpose - Although e-learning has this advantage, currently many organizations have failed to recognize the necessity for basic e-learning educational training. It follows that practitioners working in the above organizations face the difficulty of having to find educational training processes of boosting their capabilities by themselves, rather than being able to utilize the educational training processes offered by e-learning. So of their own accord, learners have considered the necessity of information relating to being able to choose between high quality educational training processes. The purpose of this study is to propose opening e-learning content information for enabling an efficient choice of learning processes related to e-learning. Research design, data, and methodology - To pinpoint the items of e-learning content information, the study was initiated according to the following process. First, information relating to e-learning content (offered on e-learning websites) was researched. Second, based on the items of information which emerged from the research, selection and validity verification took place with 5 e-learning specialists as the subjects. Third, the opinions of adult learners at K University were collated relating to the items of information which emerged from the research. Results - The e-learning content information was comprised of 16 items in order to improve the choosing process for learner's e-learning contents. The analysis results showed that when learners were choosing e-learning processes, the most highly considered item was 'mobile support' (4.35). Following this (in order) were 'tuition fees' (4.30), 'certificate issuing' (4.23), and 'awareness of educational institution' (4.18). The least considered items were 'recruiting learners' (3.01) and 'tutor support' (3.18). Conclusions - The 16 items of e-learning content information in this study, were deemed to be helpful to learners in providing them with a choice of desirable e-learning process when this process was offered to them. Following this, there is a need for service institutions offering e-learning processes to make public the information suggested by this study. Research into educational methods additionally points to a necessity for not only e-learning forms, but also offline educational methods and a combination of blended learning to be offered and run parallel to e-learning.

  • The current study examined English-speaking adult learners' production and perception of L2 Korean stops (/t/ or /t'/ or /th/) to investigate whether the two modalities are linked in utilizing voice onset time (VOT) and fundamental frequency (F0) for the L2 sound distinction and how the learners' L2 proficiency mediates the relationship. Twenty-two English-speaking learners of Korean living in Seoul participated in the word-reading task of producing stop-initial words and the identification task of labelling CV stimuli synthesized to vary VOT and F0. Using logistic mixed-effects regression models, we quantified group- and individual-level weights of the VOT and F0 cues in differentiating the tense-lax, lax-aspirated, and tense-aspirated stops in Korean. The results showed that the learners as a group relied on VOT more than F0 both in production and perception (except the tense-lax pair), reflecting the dominant role of VOT in their L1 stop distinction. Individual-level analyses further revealed that the learners' L2 proficiency was related to their use of F0 in L2 production and their use of VOT in L2 perception. With this effect of L2 proficiency controlled in the partial correlation tests, we found a significant correlation between production and perception in using VOT and F0 for the lax-aspirated stop contrast. However, the same correlation was absent for the other stop pairs. We discuss a contrast-specific role of acoustic cues to address the non-uniform patterns of the production-perception link in the L2 sound learning context.

  • Mobile learning is a practical learning method for busy adult learners because the mobility of digital devices can overcome the drawbacks of e-learning. However, research is strongly lacking in the theoretical exploration of mobile learning effects and functions and its empirical research. Moreover, the research of learning characteristics and learners' requirements must be considered before applying and disseminating mobile learning into the educational field. To address this shortcoming, this study conducted an online survey with 1,542 officers of the Ministry of Health and Welfare Affairs (MHWA) regarding learner recognition to mobile learning. The analysis of learners' attitudes toward mobile learning, based on age and position, indicated that subordinate workers appeared to place more value on mobile learning. Many participants preferred mobile learning because of its mobility and the effectiveness of anywhere and anytime. However, some participants continue to misunderstand mobile learning and its necessity. Therefore, consideration of learning effectiveness, the form of the content, and learner-centered learning must be reviewed in advance. This study could lead to practical implications of mobile learning.

  • The current research dealt with two areas which have been at the center of attention in the field of second language acquisition (SLA): recasts and intake. Although these two are continuously discussed in many studies, not enough research has addressed how they are related. Hence, the current research sought to identify the relationship between learner intake of language forms delivered in the form of recasts in adult EFL classrooms and learner immediate responses to recasts (i.e., uptake). The data were collected from 11 classrooms. A total of 221 recast episodes were observed and learners' responses to recasts were analyzed. On the basis of the recast episodes, multiple-choice recognition tests were developed and administrated to measure learner intake of the linguistic forms targeted by recasts. The study found that a half of recasts brought about learner intake. In addition, the learners responded to recasts in many different ways and their ways of responding were closely related to their intake of linguistic forms targeted by recasts.

  • Due to a series of online sex crimes cases and online class conversions caused by the spread of the coronavirus, alternatives to sex education in schools are urgently required. As a result of this study, the metaverse sex education platform was designed. Using this platform, learners are expected to cultivate correct adult awareness and digital citizenship. Within the metaverse platform, learners can participate more actively in learning. Instead of exposing one's name and face in a place dealing with sensitive gender issues, one can participate in education through his or her decorated avatar and participate in education much more actively than face-to-face education and express one's opinion through chat. In addition, education by level can be received regardless of time and place, which can have the effect of bridging the educational gap between urban and rural areas. In this paper, we propose a new sex education platform without time and space constraints by utilizing metaverse.

  • 최근 몇 년에 걸쳐 우리나라 스마트폰 사용자가 급격히 늘어났다. 이들 중에서 영어 학습에 스마트폰을 이용하고자 하는 사람들이 많아졌다. 이에 본 연구에서는 우리나라 성인 영어 학습자 100명을 대상으로 스마트폰 사용 관련하여 활용 정도, 영향 요인에 대해 조사를 하였다. 그리고 이 일반 성인 영어 학습자 집단과 비교될 수 있는 집단으로 스마트캠퍼스 환경에서 스마트폰으로 영어를 학습할 수 있는 사이버대학교 재학생 62명의 응답을 비교 분석하였다. 분석 결과 두 집단 모두 스마트폰 사용을 긍정적으로 보면서 많이 사용하고 있었고, 계속 사용할 의도를 갖고 있었다. 영어 학습 관련하여 이들은 스마트폰을 이용해서 영어를 배울 의사가 많았고, 30분 이내의 짧은 시간 동안 학습하는 콘텐츠를 선호하였다. 학습하고자 하는 영어 콘텐츠로는 듣기와 읽기처럼 수용적 기술(receptive skill)과 발음과 어휘 등 짧은 단위로 학습할 수 있는 콘텐츠를 선호하였다. 그런데, 두 집단 모두 실제 영어 학습 관련하여 스마트폰에 설치한 영어 학습 앱은 많지 않았고 만족하는 앱도 많지 않았다. 스마트캠퍼스 환경에 있는 사이버대 재학생들도 스마트폰 사용과 관련하여 전반적으로 일반 영어 학습자 집단과 비슷한 응답을 보였으나, 스마트폰을 이용한 영어 학습에 대해서는 다소 유보적인 태도를 보였다. 이는 스마트캠퍼스를 구축하여 스마트러닝을 통한 학습 성과를 얻고자 하는 교육기관의 목적이 아직 제대로 달성되지 못한 상황을 보여주는 것이다.
