In this paper, we propose a virtual learning platform based on various interactions that occur during real class activities, rather than the existing content delivery-oriented learning metaverse platform. In this study, we provide a learning environment that combines AI and a virtual environment to solve problems by talking to real-time AI. Also, we applied G-learning techinques to improve class immersion. The Virtual Edu platform developed through this study provides an effective learning experience combining self-directed learning, simulation of interest through games, and PBL teaching method. And we propose a new educational method that improves student participation learning effectiveness. Experiment, we test performance on learninng activity based on real-time video classroom. As a result, it was found that the class progressing stably.

The purpose of this study is to analyze the learners' satisfactions of the video conferencing for global engineering education and provide the implications for effective video conferencing. This study analyzed the learners' satisfactions on their participation in the video conferencing. We conducted a questionnaire survey with 132 subjects who studied in the video conferencing universities, and performed interviews with 27 learners. The results include learners wanted to have more practical themes to satisfy their interests; faculty roles among domestic professors and abroad professors should be specified: distance learners should be guided to have diverse interactions among themselves. The implications are explored for the future study and video conferencing practices.

The aim of this study is to design a Real-time video Korean curriculum. Curriculum using real-time video, which is a variant of distance learning, teaches Korean to students studying in distant places through real-time video communication program. This is expected to supplement the lack of interaction in existing video classes and enable online simultaneous interaction, while increasing learning opportunities for Korean language students living in distance places. To find out the needs of the subjects for the curriculum design, this study conducted a one-on-one interview with 9 female married immigrants who are enrolled in the Cyber University which is opening a curriculum later. According to the survey, the students answered that they have a high intention of attending classes if the lack of interaction in existing distance classes are supplemented. Therefore, we could confirm the demand of a curriculum consisting of an overall real-time video education and multilateral individual connection. Also, we found out that there is a demand in performance rather than comprehension and a high demand for detailed feedback from the teacher. The result shows that the curriculum needs to establish performance-oriented contents to progress to an advanced level Korean Language, and include a study plain comprising of real-time interaction.

원격 교육 시스템에서 화상 교육의 기능을 제공하는 교사나 학습자가 모두 카메라가 달린 PC 앞에 앉아서 약속된 시간에 개설된 교과목으로 세션으로 들어가서 수업을 진행하고, 학생들의 질문 요청이 있을 때, 이에 대한 답변을 파일 또는 화상으로 제공하고 있다. 그러나, 강의실에서 프로젝트 등을 이용하여 강의를 할 경우의 강의 장면을 실시간으로 원격지 학생들에게 제공할 수 있는 기능들에 대해서는 현재 가상 대학 시스템에서 고려를 하지 않고 있는 것 같다. 따라서 본 논문에서는 실시간 원격 강의를 효율적으로 수행할 수 있는 환경을 제공하기 위한 시스템을 설계하고 이에 대한 프로타입을 만들었다. 본 논문에서 제안하는 시스템을 가상 대학에서 뿐만 아니라 여러 분야에서 원격 프리젠테이션이 필요할 때 효과적으로 이용할 수 있으리라 생각된다.

The influence of COVID 19 has a direct impact on the education field. In the situation where non-face-to-face classes are inevitably required, interest in the learning satisfaction and intention to use real-time video conferencing is increasing. This study analyzed the effects of learner-teacher interaction, social presence, availability, self-efficacy and academic engagement as video conferencing characteristics and learner's characteristics on perceived usefulness, perceived ease of use, learning satisfaction and intention to use video conferencing. The results of this study showed that learner-teacher interaction, availability, and self-efficacy had a positive effect on perceived ease of use, and all variables except availability had a positive effect on perceived usefulness. Also, perceived usefulness and ease of use were factors that increased learning satisfaction and video conferencing use intention, and learning satisfaction was identified as variables that increased video conferencing use intention. This study has significance in that it provided various theoretical and practical implications for real-time video conferencing which will be used in many educational fields in the future through empirical analysis.

초고속 인터넷의 확산으로 인해 교육시스템이 서서히 바뀌어가고 있다. 칠판과 책, 노트, 펜을 이용한 수업이 빔 프로젝트와 컴퓨터를 통한 수업으로 대체되어가고 있고, 나아가 인터넷을 이용한 사이버 교육시스템이 점차 확산되고 있다. 사이버 교육을 통해 공간의 제약성을 무너뜨리고, 교통비와 이동 시간 등을 절약할 수 있을 뿐만 아니라 다운로드한 강의 자료를 Off-Line 상에서 반복 학습 할 수 있다는 커다란 장점이 있다. 이런 사이버 원격 교육에는 크게 3가지의 데이터, 즉 음성, 화상 및 판서 데이터가 있는데, 본 논문에서는 이 데이터들을 어떻게 하여 효율적으로 데이터를 관리할 수 있는 지, 그리고 강의 자료를 제작시 어떻게 하여 강의 제작 및 수정이 용이할지에 대해 그 구현 방안을 제안한다.

Distance learning is becoming recognized as the key to meeting the needs of more people on more subjects with cost-effective way. The purpose of this paper was to review the literature and current information related to distance education. The topics include, the characteristics of distance education, definitions of distance education, various applications of distance education, and needs of distance education in our society. This paper focused on lastest technologies of distance education such as two-way videoconferencing, e-mail, and on-line classroom. Suggestions for the effective implementation in our educational environments that include, proper teacher training and as an interactivity of the distance education program were discussed.

원격강의 방식은 일반 면대면 수업 방식과 비교할 때 교수자와 학습자의 실시간 질의응답이 잘 이루어지지 않는 점과 학습자의 흥미도와 집중도를 높이기 어려운 단점이 있다. 이러한 단점을 보완하기 위하여 일부 웹사이트에서는 메신저 등을 사용하기도 하지만, 키보드에 익숙하지 않은 학습자는 학습 도중에 키보드를 통해 질문을 하는데 많은 어려움을 겪을 수 있다. 그러나, 실시간 음성과 화상통신(H.323)과 SIP을 사용하면 교수자와 학습자간에 또는 학습자와 학습자들 간의 질의응답을 보다 편리하게 처리한 수 있고 공동체 활동을 활성화 할 수 있다.

In the database design course, the team project is a very important process to develop students' database design competencies. In order to carry out team projects smoothly, active interaction between students and the professor as well as collaboration among team members are very important. However, a full uncontacted class was suddenly decides in the first semester of 2020, it was questionable whether it would be possible to effectively manage this course, where team projects to construct database take up a big portion. However team projects were able to proceed without major problems through interaction using real-time video media such as zoom, and discussions, quizzes, and Q&A supported by the online education support system (LMS), and online presentations, mutual evaluations, and so on. This paper shares the experience of managing engineering team projects in uncontacted classes and based on three surveys introduces desirable improving directions of this instruction and some suggestions to improve uncontacted classes overall.

In this paper, we analyzed the misconceptions and errors incurred during factorization learning. We also examined whether online individualization classes had a positive effect on students' mathematical achievement. The experiment was conducted for 4 weeks (16 times in total) on middle school juniors in rural areas of Gyeonggi Province, where the influence of private extra education was small. In the class, the 'Google Classroom' was used as a LMS, the video lecture was uploaded to YouTube, and the teacher interacted with the students through "Zoom" and "Facetalk". In the online class situation, students' assignments and test answers were checked in real time through 'Google Classroom', and immediate feedback was provided to the experimental class group's students. However, for the control group students, feedback was provided only to those who desired. A total of 7 achievement evaluations were conducted in the order of pre-test, formative evaluation (5 times), and post-test to confirm the change in students' ability improvement and achievement. Through the formative evaluation analysis, it was possible to grasp the types of errors and misconceptions that occured during the factorization process. Students' errors were divided into four types: theorem or definition distortion error, functional errors such as calculation, operation, and manipulation, errors that do not verify the solution, and no response. As a result of ANCOVA, the two groups did not show any difference from the 1st to 4th formative assessment. However, the 5th formative assessment and post-test showed statistically significant differences, confirming that online individualization classes contributed to improvemed achievement.
