This study aims to analyze lesson plans prepared by prospective non-native Korean language teachers, examine the characteristics of non-native Korean language teachers as a group, and recommend efficient measures for Korean language education practicum. While the interest of researchers in Korean language teachers has increased, they have focused mainly on native teachers. Although research on non-native Korean language teachers has increased recently, previous studies have not examined lesson plans prepared by prospective non-native teachers. Thus, this study analyzed the composition and content of 30 grammar lesson plans prepared by foreign students undergoing Korean language education training at universities in Seoul. The results showed a lack of diversity in types of exercise and task activities from a compositional perspective. Furthermore, the content quality was often attributable to their language proficiency. Based on this, measures were proposed to enhance the educational effectiveness of Korean language education courses for prospective non-native Korean language teachers.

박진철(Park Jinchul) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.10

본 연구는 2000년 이후 발표된 한국어교육에서의 멀티미디어 활용 연구의 동향을 살펴보는 데에 목적이 있다. 이러한 연구 동향의 분석은 한국어교육에서의 멀티미디어의 관련 연구 쟁점을 살펴보고 향후 방향성을 모색하고 연구 영역에 대한 논의가 가능할 것이다. 이를 위해 한국학술정보서비스(RISS)를 통해 한국어교육에서 멀티미디어 관련 연구가 활발히 수행된 2000년대 이후 발표된 석사 및 박사 학위 논문과 주요 학술지 게재 논문 257편을 2019년 1월부터 3개월 간 검색한 후 연구물의 시기별, 유형별(학위논문, 학술지), 주제별 연구 동향을 살펴보았다. 우선 연구를 위한 분석 대상 및 절차를 기술하고 기술의 발달과 학습 형식의 변화에 따라 새롭게 등장한 용어를 정리하였다. 멀티미디어의 활용 연구는 시기별로 2000년대 초반에는 연구물의 수가 많지 않았으나 2010년부터 급격히 늘어난 것을 확인할 수 있었다. 이는 모바일 기기의 보급과 무선 인터넷 통신 기술의 발달에 기인한 것으로 기술적 환경이 조성과 새로운 교수・학습 모형의 등장과도 무관하지 않다. 유형별 연구 동향 분석 결과 대부분이 학술지와 석사 학위 논문에 치우쳐 유형별 편중성이 심각했다. 학술지의 경우 한국어교육 관련 대표 학술지가 높은 비중을 차지하였고 기타 학술지의 경우 교육학, 교육공학, 멀티미디어학, 컴퓨터・정보통신공학 등으로 다양했는데 이는 한국어교육에서의 멀티미디어 관련 연구가 세부 주제 측면에서 하나 이상의 범주에 속하는 특성에 기인한다고 볼 수 있다. 기능적 측면에서의 연구 동향은 학습자 중심의 자가 학습을 위한 프로그램 개발 관련 연구가 가장 많았 고 다음은 교사 중심 수업에서 시청각 자료로서의 도구적 활용 방안 연구 순이었다. 한국어교육 측면에서 연구 동향은 멀티미디어의 교육적 적용 및 활용을 다룬 ‘교수법 일반’으로 분류될 수 있는 연구가 가장 많았으며 교육과정 개발 및 분석 연구, 교수 자료 개발 연구 등의 순이었다. 또한 교육 내용에 대한 분류는 언어 기능 교육 을 위한 멀티미디어 활용 연구가 가장 많았고 다음으로 언어 지식 교육 연구가 그뒤를 이었다. The purpose of this study is to look at trends in multimedia utilization studies in Korean language education published since 2000. This analysis of research trends will allow us to look at related research issues in multimedia in Korean language education, explore future directions and discuss areas of research. To this end, we examined 257 master s and doctorate papers published in major journals and 257 papers published since 2000 when multimedia-related research was actively conducted in Korean language education, including research trends by timing, type (degree paper, academic journal), and subject. First, the analysis objects and procedures for the study were described and the newly emerged terms were put together as the technology developed and the learning style changed. Research on the utilization of multimedia did not have much research in the early 2000s, but it has increased sharply since 2010. This is due to the proliferation of mobile devices and the development of wireless Internet technologies, and is also related to the creation of a technical environment and the emergence of new teaching and learning models. In the research trends by type, most of the studies subject to analysis were biased towards academic journals and master s thesis, which led to serious bias by type. However, the distribution of academic journals was attributed to the characteristics of one or more categories of multimedia research in Korean language education, as well as those related to education, multimedia, computer and information communication engineering. First of all, research trends in functional aspects led to studies related to the development of learning materials for learner-oriented self-learning, followed by the research on tooling utilization as audiovisual material in teacher-centered classes. In terms of Korean language education, research trends were most frequently classified as professional law general, which deals with the educational application and utilization of multimedia, followed by research on curriculum development and analysis and research on teaching materials development. In addition, classification of educational content was the largest study of multimedia utilization for language functional education, followed by language knowledge education research.

인공지능(AI)을 활용한 한국어 듣기 교육 자료 제작 연구 -음성합성기술(TTS) 활용을 중심으로-

박진철 ( Park Jinchul ) 이중언어학회 2021 이중언어학 Vol.82 No.-

Although the scope of application of artificial intelligence(AI) related technologies has been expanding to various fields over the past decade, research on utilization in Korean language education has been minimal. Therefore, in this study, we sought to explore the educational use of listening material produced by the TTS program. First of all, as a result of the listening evaluation on learners, there was no significant difference between the sound source recorded by a professional voice actor and the listening material using the TTS program. Second, Listening materials were evaluated for Korean teachers. ‘Pronunciation’ could be considered good overall. 'Intonation and Accent' needs to be elaborated according to context of situations, including the speaker's feelings. and that ‘time factors’ can be accepted naturally in general, but some sentences were awkward. Third, after analyzing the accuracy of the listening material produced through the STT program, 96%, the pronunciation of the listening material was generally clear. Overall, the listening material produced by the TTS system has been evaluated in various ways, and the possibility of educational use in the Korean language education field can be evaluated positively. However, expanding the scope of the TTS program requires continuous performance improvement efforts. (Yonsei University)

박진철 ( Park Jinchul ),장지영 ( Jang Jiyeong ) 연세대학교 언어연구교육원 한국어학당 2020 외국어로서의 한국어교육 Vol.59 No.-

The purpose of this study was to examine the type, frequency, and characteristic aspects of feedback after conducting peer feedback activities in online Korean writing classes using Zoom for foreign university students and to find out the educational utility and learners’ satisfaction of peer feedback. Peer feedback activities were conducted for sixty students in academic Korean writing classes for one semester in four domestic universities (or graduate schools). Using Zoom, students’ writings were shared during the class and feedback was provided by peers. The results of quantitative analysis of the contents and the style of peer feedback were as follows. First, the contents of feedback were provided in the order of content, vocabulary and expression, grammar, and spelling. Second, the way of feedback was used frequently in the order of pointing out errors, suggesting alternatives, paying compliments and asking questions. In addition, a follow-up in-depth interview was conducted to analyze learners’ perception of peer feedback on aspects of educational utility and satisfaction of feedback. 78% of the students surveyed responded positively to motivating learners to study Korean, giving confidence and having interest, which means that peer feedback activities in writing class had an significant effect on the satisfaction of writing classes with educational utility.

학문 목적 한국어 말하기 수업에서의 음성합성기술(TTS) 활용 사례 연구 -‘발표하기’ 과제를 중심으로-

박진철 ( Park Jinchul ) 국제한국어교육학회 2021 한국어 교육 Vol.32 No.3

The purpose of this study is to apply the TTS(Text-to-Speech) program to the field of Korean language education and to improve presentation skills by leading input/output activities. In this study, learners’ perceptions were examined through a survey after using listening material produced by the TTS program in intermediate Korean speaking classes for foreign students. The Korean speaking class focused on presentation. In the class, the presentation written by the learner was produced as a listening material using the TTS program and distributed to the students. It also induced input/output tasks by presenting students with tasks to record after listening to the listening material and practicing presentation. At the end of the semester, the final composition written by the students was produced as listening material and distributed to provide a model for pronunciation practice. As a result, it was confirmed that the use of TTS program in academic speaking classes provided sufficient input/output opportunities for students to learn Korean speaking and listening. However, it was confirmed that the task of improving the performance of TTS programs remained to produce listening material close to natural languages. (Yonsei University)

WBAN에서 신체 내부 센서의 라이프타임 향상을 위한 LI 프로토콜

박진철(Jinchul Park),이정규(Jongkyu Lee) 대한전자공학회 2014 전자공학회논문지 Vol.51 No.6

WBAN(Wireless body area network)에서 신체에 삽입된 센서는 신체의 생물학적인 특성에 의해 일반 센서보다 프레임의 오류가 발생 할 확률이 높아진다. 본 논문에서는 신체에 삽입된 센서의 라이프타임을 향상시키기 위해 삽입 된 센서의 재전송을 외부 센서에서 대신 전송해주는 방법으로 삽입된 센서의 전송을 줄이는 방법을 제시한다. 제시된 LI(Lifetime Increment) 프로토콜은 기존의 CSMA/CA 전송방식에서 데이터 프레임에 외부 센서의 ID를 추가하고, 내부 센서가 전송한 프레임이 재전송이 요구 될 시에는 추가 되어있던 ID의 외부 센서에서 재전송을 책임지는 방법이다. 제안하는 프로토콜의 성능 비교를 위해 WBAN CSMA/CA 전송 방식과 비교한 결과 에너지 소모량이 적어져 라이프 타임이 향상되는 것을 확인하였다. A implanted sensor’s error probability is more likely to external sensor’s error probability by biological characteristic in WBAN. In this paper, we present method that external sensor transmits frame instead of doing implanted sensor’s retransmission for improving lifetime of implanted sensors in WBAN. The proposed method, LI(Lifetime Increment) protocol is to add external sensor"s id in transmission data frame of a implanted sensor. When the retransmission is required, external sensor that have to registered id in data frame retransmits frame instead of implanted sensors" retransmission. The comparison result shows that the proposed protocol reduces power consumption and improves life time.

한국어 교육용 익힘책 유형 분석 연구

박지순(Park Jisoon),민진영(Min Jinyoung),박진철(Park Jinchul) 한국문화융합학회 2021 문화와 융합 Vol.43 No.12

본고에서는 체계적인 익힘책 개발을 위한 원리를 도출하기 위해 선행 연구 검토하여 익힘책의 역할과 기능을 설정하고, 이를 바탕으로 익힘책 5종의 유형 분류를 실시하였다. 분석 대상 익힘책은 교육 시수에 따라 200시간 교육과정과200시간 미만 교육과정으로 나누었고, 익힘책의 유형은 주교재 보완 기능, 학습 목표 구현 기능, 맞춤형 학습 기능, 자율 학습 기능의 네 가지로 구분하여 분석하였다. 분석 결과, 초급의 경우 분석 교재 5종 중 서로 다른 교육과정을 배경으로 하는 2종이 동일 유형이고, 나머지 익힘책들은 그 유형이 서로 다른 것으로 나타났다. 중급 익힘책 역시 분석 교재 4종 중 서로 다른 교육 시수를 배경으로 하는2종만이 동일 유형으로 나타났고, 고급의 경우에는 교육과정이 다른 2종이 서로 다른 유형을 보였다. 그리고 1종을 제외하고 동일 교재의 익힘책은 초급, 중급, 고급 수준이 모두 동일한 유형으로 개발되어 있었다. 이렇게 익힘책은 교육 시수라는 교육 환경의 차이나 숙달도 수준별로 공통적인 특징을 보이지 않고 교재마다 다른 양상을 보이고 있음을 확인할수 있었다. 이는 교육 기관별 주교재의 집필 방향에 준해서 익힘책이 개발되었기 때문인 것으로 판단된다. 이러한 익힘책분석과 선행 연구 검토를 통해 본고에서는 익힘책 개발의 원리로 다섯 가지를 제시하였다. In order to derive principles for the workbook development, this study reviewed prior studies to establish the roles and functions of workbook and conducted classification of five types of workbook based on them. The analysis workbook was divided into 200 hours of curriculum and less than 200 hours of curriculum according to the number of curriculum sessions, and the types of workbooks were divided into four: main textbook complementary function, learning objective implementation function, customized learning function, and self-regulative learning function. According to the analysis, two of the five beginner s workbook set in different curriculum are the same type, and the rest of the workbooks are different types. Intermediate level’s workbook also showed only two of the four analytical workbook with different educational times in the background, and two of the advanced workbook showed different types of curriculum. In addition, except for Type 1, the same workbook was developed with the same level of beginner, intermediate, and advanced. It was confirmed that the mastery of the educational environment, called education time, showed no common characteristics by level and showed different characteristics of each workbook. This is believed to be due to the development of workbooks in accordance with the direction of writing main textbooks by educational institutions. Through these workbook analyses and prior research reviews, this paper presents five suggestions for workbook development.
