코로나로 인해 비대면 온라인 수업으로 운영된 수업환경에서 컴퓨터공학 분야의 대표적인 실습기반 교과목인 프로그래밍 수업은 학습자들에게 온라인 수업이지만 대면 수업의 실재감을 제공하는 질적 개선 방법을 모색할 필요성이 대두되었다. 본 연구는 플립러닝에 기반 한 실시간 수업을 활용하여 실습 기반 프로그래밍 수업에서 학습자의 능동적 수업 참여를 유도하고, 교수자와 학습자, 학습자와 학습자 간의 상호작용이 원활한 수업을 통해 대면 수업 수준의 실재감을 학습자에게 제공하고 학습효과를 높이고자 하였다. 적용결과, 온라인 수업에서 플립러닝 기반 수업 설계가 실습 기반 수업에 대면수업 수준의 학습 효과 및 만족도가 있었음을 조사·분석하였다.

최근 코로나19 발생으로 산업 및 교육의 형태가 변화하였다. 많은 교육 기관에서 갑작스러운 비대면 수업이 진행됨에 따라 교수자와 교육생 모두에게 온라인 수업 환경에 대한 불편이 존재하고 있다. 기존 원격 회의 플랫폼의 경우 화상회의를 주 목적으로 개발된 기업용 플랫폼이기에 수업 환경에 적합하지 않다. 이에 본 논문에서는 해당 질병이 안정화 된 이후에도 이와 같이 집합 교육이 불가능한 상황에 대비하여 수업은 교육자 중심의 발언으로 진행되며 교육자는 교육생의 상태를 확인하거나 교육생과 교육자로 그 역할이 완전히 구분되고, 클라우드 PC를 통해 고사양 PC를 가지고 있지 않은 교육생도 고화질 영상 전송 및 프로젝트 실습이 가능하기를 희망한다.

최근 COVID-19의 확산에 따라 비대면 학습의 중요성이 화두로 오르고 있다. 과학관과 같은 다중이용시설을 이용하는 방법에서 각 학교, 또는 가정에서 지도할 수 있는 교육 방법의 변화 또한 논의해야 할 때이다. 특히 천문학 교육의 장으로 활용되고 있는 천체투영관(Planetarium)은 다중이용시설로, 상황에 따라 여러 가지 제약을 가지므로 시·공간 제약을 받지 않는 교육프로그램의 개발이 필요하고 볼 수 있다. 본 연구에서는 천체시뮬레이션 소프트웨어를 활용한 스크립트 제작 및 360° VR 영상 제작기술을 개발하고 온라인 플랫폼을 활용하여 천체투영관을 방문하지 않은 비대면 환경에서 도 참가자개인의 휴대기기등을 통한 몰입도 높은 천문학 교육을 구현할 수 있는 프로그램을 개발하여 새로운 환경에 대한 적용 기회를 제공하고자 한다. 나아가 개발한 프로그램을 천체투영관에 적용하여 천체투영관 활용 천문학 교육프로그램과 교육과정과 연계한 교육콘텐츠 개발에 활용되기를 기대한다.

This study compares Online SW-based maker education in terms of self-efficacy, learning motivation, and interest after applying differently according to blended learning strategies. First, a SW maker program for blended learning was developed and applied as a live seminar-type class including real-time interactive and a support-providing class consisting of online content and Q&A. As a result of comparing the differences between students according to the two strategies divided into pre- and post- survey, in the self-efficacy part, there was a significant difference in the positive efficacy and the overall part, and in the learning motivation part, the live seminar form was significantly higher in the confidence part. In the interest part, the support-providing form showed a significantly higher average in the instrumental interest and nervous part. In order to maintain the effect of maker activities like existing face-to-face situations in Online learning, it is necessary to increase sharing time between students, an integrated learning environment, and sufficient provision of exploration time and learning materials.

Under the influence of COVID-19, as a measure of social distancing for about two years and one month, non-face-to-face services using ICT element technology are expanding not only to the education sector but to all fields. In particular, as educational programs using the Metaverse platform spread to various fields, educators, and learners have more learning experiences using Edutech, but problems through non-face-to-face learning such as reduced immersion or concentration in education are raising In this paper, to overcome the problems raised through non-face-to-face learning and develop metaverse immersive media digital contents to improve the educational environment, we utilize VR (Virtual Reality) based on an immersive metaverse to provide education / Training contents and the educational environment was established. In this paper, we presented a system to increase immersion and concentration in educational contents in a virtual environment using HMD (Head Mounted Display) for learners who are put into military education/training. Immersion was further improved.

This study aims to break away from uniform academic regulations in preparation for nurturing future talents for the 4th industrial type, and apply the intensive course system to promote exchange and competition in the global education market. We would like to suggest a way to learn efficiently in an environment. To this end, we analyze the literature and prior research on design subjects in the intensive course system and non-face-to-face environment, analyze the requirements of teachers and students in charge of actual design subjects, and propose a utilization plan through expert review, and apply the persona technique. presented. This study will be able to provide basic data that can be practically used when operating intensive course design courses in the future.

2020년 전자서명법 개정으로 공인인증서가 폐지됨에 따라 자체 인증 기술의 도입이 필요한 실정이다. 특히나 COVID-19로 인한 비대면 상황이 지속됨에 따라 기존 아날로그 방식을 통해 대면으로 계약서를 작성하고 수립하는데 많은 비효율적 문제가 대두되었다. 디지털 전환 가속화와 비대면 거래확대로 인한 전자 신원확인 중요성이 점차 커지고 있음에 따라 전자 서명 및 전자 봉투 방식으로 계약할 수 있는 안전한 시스템 개발을 진행하고자 한다. 이를 위해 계약 시스템의 보안 요구 사항을 도출하였으며 최종적으로 NFT 연동을 통해 안전한 계약을 진행할 수 있도록 프로세스를 설계하였다. 시스템의 동작 방식을 표현하기 위하여 DFD 등을 포함한 Diagram 형태로 나타내었으며 실제 프로토타입을 제작 후 블록체인 네트워크에 연결한 뒤 테스트를 진행하여 시스템 검증을 수행하였다. 추후 이 시스템을 통해 B2B, B2C 모델 등의 모델 기반 다양한 거래와 계약이 가능하도록 구성할 예정이며 추가적인 연구를 진행하여 사용자 측면에서 더 간편하고 안전한 환경이 될 수 있도록 고도화 시키는 것을 목표로 한다.

The purpose of this study is to identify the antecedents and consequences of perceived fairness of assessment in an online class, such as Google classroom. Based on an extensive literature review, a research model and research questions were designed. We found that the perceived interactivity of contents and social presence were found to be antecedents of perceived fairness of assessment. Further, perceived fairness of assessment was found to have a substantial influence on class satisfaction and achievement.

Due to the recent coronavirus outbreak, many universities in Korea have started to implement remote education. Accordingly, the Ministry of Education has stated its plans to continuously encourage and maintain remote learning as the future innovation model for education and suggested the need for a diverse range of remote learning models. However, studies on the development of practical learning models have not been carried out actively until now. Particularly, there are not many case studies in the field of design, especially regarding mobile website development. As means to improve the newly designed practice environment, this study therefore proposes the "modoo" project that offers domain creation and online marketing services. As a result of this study, the researcher suggests the use of a mixed(blending) teaching method and realized that the effectiveness of education multiplies when project-based learning and flipped learning is combined appropriately. The research methodology was divided into two big sections, education content and operations, and the effect was evaluated using the course evaluations. The study results confirmed that the applicability will increase given that learning satisfaction levels increased by more than 5% compared to face-to-face learning.

This study aimed to investigate the feasibility of an interactive singing-based synchronous videoconferencing program for children with autism spectrum disorder (ASD). This study was conducted in four stages: analysis of interactive singing tasks in the literature for children with ASD, examination of differences in perception of sounds transmitted via synchronous videoconferencing platform depending on the type of singing tasks and accompaniment, construction of singing-based synchronous videoconferencing program and determination of its validity, and implementation of the constructed program with three children with ASD and confirmation of its feasibility. The results showed that different types of singing tasks and accompaniment affected perception of sounds transmitted online, which highlights the importance of considering such effects when designing synchronous videoconferencing music therapy programs. Also, increases in program engagement and singing behaviors were observed for all three participants, and their caregivers reported high levels of satisfaction with the program. The findings support the applicability of this intervention as a tele-music alternative during the COVID-19 pandemic. Clinical implications and suggestions are discussed.
