The purpose of this study is to analyze the experiences of teachers who participated in the development of online science class videos in the context of covid-19, their perception of online science class, and the characteristics of the online science class content developed by teachers. A survey and interviews were conducted with ten elementary school teachers who made online science class videos themselves. Also the characteristics of the online science class were investigated by analyzing the online science class video produced by the participants. As a result, participants in the study recognized the lack of production time, difficulty in filming and editing, concerns over misconceptions, the problem of solving copyrights for existing materials, and the burden of external disclosure. Although it was a teacher who had experience producing online science class video contents, no research participants actively answered the merits of online science class. On the other hand, the study participants cited that the shortcomings of online science classes were that students had fewer opportunities for inquiry and lack of communication or interaction. In particular, these shortcomings were thought to have a great influence on the quality of online science classes, especially in making inquiry classes difficult. Some teachers took a negative view that online science classes could not completely replace face-to-face classes. However, if multiple teachers are presented with supplementary teaching activities that complement the content-based online teaching method, the method of combining online science classes and face-to-face classes is not. Through the analysis of the contents of the online science class, the introduction and arrangement steps of the online science class were similar to the process of the face-to-face science class, but the inquiry step and the conceptual explanation step showed a big difference from the face-to-face science class.

This study explores what factors influence college students' synchronous online learning satisfaction and what advantages and disadvantages exist when it comes to taking synchronous online learning courses. In-depth interview results suggest that advantages of synchronous online learning are convenience (no need for travel, no limitation for study place), saving money, and no worry for contracting Corona 19. However, disadvantages of synchronous online learning are instability of online learning system, lack of interaction between learners and educators, difficulty of instant communication, low education quality, and unfairness of exams. This study found that college students taking synchronous online course think that synchronous online learning is more appropriate for theory-based course than practice-based courses in that theory-based courses are lecture-oriented while practice-based courses require interactivity between learners and educators. This study provides educators a baseline understanding on how college students think over synchronous online learning and how to enhance students' satisfaction with synchronous online learning.

Sudden implementation of online classes in higher education due to Covid19 pandemic implies a lot of worries about academic performance declining. Thus, this paper analyzed a class(CalculusI) taught 100% online which was the same as the offline class before. This class tried to maintain the same quality as the offline one by utilizing various teaching strategies. The result shows the academic achievement level was similar or higher than that of offline class, and so was the students' perception and satisfaction degree. However, this was not just the outcome of online class, but it came from the professor's well-designed teaching plan and smooth operation of the class. It implicates successful teaching methodology is more important factor than such medium difference as online or offline. This study suggests the potential of online classes after the Covid19 pandemic, and expects further studies verify the result in a lot more curricula.

2020학년도 1학기는 외부 환경 요인으로 인해 대학교육시스템에 큰 변화가 발생한 시기라고 할 수 있다. 컴퓨터공학 분야의 대표적인 실습기반 교과목인 프로그래밍 수업에서 학습자들에게 온라인 수업이지만 대면 수업의 실재감을 제공하는 방법을 모색할 필요성이 대두되었다. 본 연구에서는 다양한 유형의 수업 방식을 온라인 수업에 활용하여 대면 수업 수준의 실재감을 학습자에게 제공하고 학습효과를 높이고자 하였다. 강의 동영상 수업과 상호작용을 포함한 실시간 수업을 혼합하여 수업한 후 설문 조사를 통해 실시간 수업을 선호하는 학습자들이 수업목표인 프로그램 개발 능력을 타 학습자들보다 잘 습득하여 수업 만족도가 높았고, 이를 통해 온라인 수업에서 실시간 수업이 능동적인 학습자들에게는 대면 수업과 동등한 수준의 학습 효과가 있었음을 조사·분석하였다.

현재 코로나 사태로 인해 많은 학교에서 온라인으로 수업이 진행되고 있지만 대면강의에 비해 온라인수업은 진행자와 수강자의 상호작용이 원활하지 않아 집중도가 떨어지는 문제가 있다. 따라서 본 논문에서는 진행자가 전체 수강자의 집중도를 파악하고 전체적인 집중도가 낮아졌을 때 진행자에게 메시지를 전송하여 적절한 주의/환기 등을 줌으로써 온라인수업의 집중도를 향상시킬 수 있는 온라인 수업집중도 분석시스템을 제안한다. 본 시스템을 활용하여 수강자의 집중도 향상 뿐만 아니라 수업의 진행 방향을 조절할 수 있으며 상호작용을 가능하게 하여 수업의 질을 향상시킬 수 있다. 본 논문의 시스템은 dlib 의 안면 검출기와 OpenCV 및 PyQt5 의 QtDesigner 를 사용하여 프로토타입을 구현하였다.

This study aimed to understand and analyze the learners' class satisfaction and the effectiveness of synchronous online classes after COVID-19. A total of 188 learners participated in the survey conducted at the end of the Fall Semester 2020 at C University located Gyeongsangnam-do. Findings revealed that learners' satisfaction with the synchronous online classes was relatively low, and the learners had negative perception of that. Learning content have the biggest effect on the learners' class satisfaction. Next came class management and the online learning platform. Therefore, instructors need to organize learning content effectively and enhance learners' understanding considering the most influential variable, learning content so that learners are satisfied with the synchronous online classes. Also, instructors should make it possible for learners to get familiar with the online learning platform and use it without any problems through systematic and faithful class design for effective learning in unfamiliar online learning environment. In addition, instructors need to know learners' needs and difficulties and plan their synchronous online classes. This study has limitations in that it was conducted only at one college and the limited number of variables was measured.

The purpose of this study is to explore the current status and effects of online discussion classes in universities. To this end, a survey was conducted on university students attending a total of four universities in Seoul and Gyeonggi Province to diagnose their perceptions of the operation of online discussion classes and their effects. The collected data were analyzed using frequency analysis, descriptive statistical analysis, cross-analysis, F-test, T-test, and Scheffe test by applying SPSS program. As a result of the study, first, it was found that 'non-real-time recorded lessons' and 'real-time interactive video lessons' were mainly conducted at universities after the COVID19 crisis. Second, in the online class method, 'real-time interactive video class' had a positive effect on 'debate class preference' and was found to be more meaningful. Third, college students recognized participation in online discussion classes as a foundation for expanding creative thinking skills, suggesting that strengthening through smooth communication and exchanges based on learners' sufficient cognitive processes on discussion methods and procedures is more helpful.

비실시간 온라인 수업은 학습자가 원하는 시간에 학습을 할 수 있고, 공간의 제약이 없다는 장점이 있다. 그러나 실시간으로 이루어지는 수업이 아니다 보니 수업 콘텐츠에 문제가 있거나, 설명이 부족한 부분에 대한 학습자들의 의견이 교수자에게 전달하는 것에 한계점이 존재한다. 본 논문에서는 수업 콘텐츠를 듣는 학습자들의 피드백 정보를 교수자에게 전달하는 시스템을 제안한다. 학습자에게는 온라인 녹화 수업 콘텐츠를 정지했을 시 정지 사유를 조사하고, 정지 사유와 정지한 콘텐츠의 시간 정보를 교수자에게 전달할 수 있고, 교수자에게는 학습자들의 온라인 녹화 수업 영상의 피드백 정보와 정지시간을 교수자에게 그래프로 나타내어 한눈에 수업 콘텐츠의 문제점이 많은 부분을 파악할 수 있게 해서 전달한다. 교수자는 피드백을 반영해 콘텐츠를 재업로드하여 질 높은 수업 콘텐츠로 인해 학습자들은 학업 성취도를 높일 수 있을 것이다.

This study was aimed to grasp online learning quality satisfaction in Dental Hygiene students. A survey was conducted targeting finally 228 dental hygiene students at a university in Gangwon Province from February 3, 2021 to February 17. As a result of analysis, the online class satisfaction by good instruction component was lower overall than importance. The learning environment satisfaction was lower than its importance. A difference between importance and satisfaction with online learning by detailed good instruction component showed a relatively big difference in systematic class, online learning environment, ability to convey the class contents. The need for online learning content was high in teaching material and VOD. The class operation type satisfaction was high in a non-real time class. Accordingly, a continuous effort is conceivably necessary for improving quality given the teaching-design establishment of online learning.
