The purpose of this study is to verify the effectiveness of non-face-to-face lectures conducted at universities in Korea under the influence of COVID-19. So this study analyzed the satisfaction level of the students according to the type of class operation, such as face-to-face classes and remote video classes. To this end, this study compared the differences in class satisfaction by class type and class size for a total of 8,707 courses operated by a university between 2019 and 2020. The study found that the satisfaction level of the remote video class was significantly high. In addition, the combination of remote video classes and face-to-face was more satisfactory than other cases. On the other hand, the satisfaction level of small classes in both face-to-face and remote video classes was higher than that of medium or large classes. This means that even remote video classes are highly satisfactory in small-scale classes. Based on the findings, the study proposes a paradigm for new college classes.

The purpose of this paper is to suggest design principles for videoconferencing using an English Native Speaker. For this, Design-Based Research which is emerging newly was applied. During the research period of 3 months, several English classes were recorded. After finishing each class, Korean teacher and Native teacher wrote reflective diary and a researcher implemented interviews to students who had this class. Based on these data, this class was divided into 3 steps which is consisted of before class, under class, and after class. And then a research analysed patterns of this class, errors, and interactivity etc. The result of this paper, because a Korean teacher and students in the classroom meet a Native speaker in the distance through the videoconferencing system, teachers who design this class should consider many aspects due to the complexity of this.

The study aims at analyzing and comparing the effect of video teleconferencing English class with native speakers on class satisfaction and self-efficacy of elementary school students according to grades. Revised Kim's self efficacy and researcher's class satisfaction measuring tools were used for this. Grade 3 got the highest score and grade 6 had the lowest one in class satisfaction. In post-testing on self efficacy, average score was lower than in pre-testing except grade 3. Grade 3 got the highest score and grade 6 had the lowest one in self efficacy. I conclude that as students' grade goes up, their interests decrease in teleconferencing class and native speaker teachers.

Through the questionnaire, I analyzed the merit, the defect and the solution of problems of the lecture using the Video Lecturing System. In the paper, we present that the Video Lecturing is a substitute tracking method by demonstrating the superiority of it. For tile purpose of this, I compared and analyzed the Video Lecturing with the general lecture from the viewpoint of the class satisfaction and the effectiveness through the results of the questionnaire obtained by students who took the Video Lecturing class.

현재 사용되고 있는 대부분의 화상 회의 및 화상 강의 시스템은 고정된 위치에 있는 카메라를 사용하므로 원격지 학습자는 고정된 장면만을 보면서 학습에 임해야 한다. 예를 들어, 강의 진행자가 카메라 시야를 벗어나 수업을 할 경우, 원격지 학습나는 강의 진행자의 모습을 볼 수 없으므로, 수업에 대한 능률이 감소될 수 있다. 따라서 화상 강의가 진행되는 동안 강의 진행자는 정해진 위치에서만 강의할 수 있도록 하는 제약상하을 부여하므로 강의 진행자에게 부담감을 안겨주고 있다. 본 논문에서는 강의 진행자가 카메라의 위치에 신경쓰지 않고 강의를 할 수 있는 환경을 제공하기 위한 영상 강의 시스템을 제안하고자 한다. 시스템은 카메라로부터 입력되는 영상을 분석하여 강의 진행자의 위치를 추적하므로 강의 진행자의 위치에 따라 변화되는 강의 환경을 적절히 촬영할 수 있다.

This study explored effective teaching-learning activities under the hybrid teaching model combining flipped learning, direct instruction, cooperative learning and distance learning. Subjects were 99 college students enrolled in 2 teacher preparation courses. Students evaluated effectiveness of 22 teaching-learning activities according to Likert scale at the end of the semester. As a result, all 22 teaching learning activities were considered effective more or less. They facilitated motivation, comprehension, participation, thinking, and led to mastery of the task. ② Activities scored low were 'questioning and answering at the beginning of online class', 'open book test'. ③ Hybrid teaching model was favored over traditional instruction. Open ended responses were consistent with the ones in the questionnaire. This research supports the notion that key teaching models to be combined for successful flipped learning in college setting are direct instruction and cooperative learning. Furthermore, effective and ineffective teaching strategies for flipped learning were found.

The main purpose of this paper is to examine the efficacy and future potential of a newly-emerging concept of a metaverse in online education environment. In order to achieve this goal, this paper showcases various scenes that happened in the metaverse classes using the ifland app. Through an in-depth analysis of theoretical grounds and preliminary survey findings of 32 university students, this study suggests that as students in a metaverse space are engaged in the interactive learning process and environment with an avatar that projects oneself, it can be an effective educational platform coming from the benefits of gamification and edutainment. In addition, a metaverse space provides existential encounters and hands-on experiences, which in turn increases the level of 3D learning immersion. It may overcome the shortcomings of online live streaming platforms such as Zoom or Webex that provide 2D experiences. Based on the findings, this paper further suggests a blueprint for online education suitable for the transition to a digital society.

This study examined how different types of remote video lectures, which universities are using in earnest now due to the COVID-19 pandemic, impact the academic achievement of learners. Zoom-based remote video lectures were divided into two types-general lecture-centered and group task-oriented-and experimental and control groups were set up accordingly. An achievement test and a questionnaire were conducted to determine how academic achievement differed between these two approaches. The achievement test revealed no significant differences in achievement scores between the two groups. Meanwhile, the questionnaire regarding satisfaction with Zoom-based video lectures indicated that both groups were highly satisfied. Participants in the general lecture-centered type group cited the effect of learning, their instructors' class preparation and attitudes towards the class, and the promotion of participation in learning activities as the causes of their satisfaction, while participants in the task-oriented type group highlighted communication and sharing, the efficiency of group discussions, and the moderate difficulty level of group tasks as the reasons for their satisfaction with the video lectures. Remote video lectures in the untact era are becoming increasingly common, and educators will need to develop various Zoom-based teaching strategies to maximize their efficiency.
