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.

In this study, the multiplicity of synchronous online class discussion activity is explored at conceptual level. From the cultural-historical activity theory (CHAT), each utterance may be considered as a product of the activity system. Alderfer's ERG theory is employed as another theoretical framework for the study. Based on the subject's existence, relationship, growth needs, their class discussion activities constitute four different dimensions: physical/biological, cultural/institutional, social/relational, and cooperative knowledge construction. It is inherent in individual activities and has a different arrangement according to their interests and situations, and at the same time acts as a factor of cooperation and competition among the participants. Through this, collective discussion activities represent complex and dynamic development patterns.

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 aimed to analyze cases of online class design by pre-service science teachers to identify the teaching strategies employed for online classes. For this purpose, the real-time online class lesson plans of 12 pre-service science teachers, who had experienced education utilizing online teaching tools for a semester, were collected and analyzed. The pre-service science teachers considered all the elements that were essential in traditional face-to-face class designs, including prerequisites, statements of learning objectives, stimulating motivation, teaching and learning methods, wrapping up, teacher-student interaction, and assessment. They devised teaching strategies that could overcome the limitations of online teaching and were not feasible in face-to-face classes for each element. Additionally, they were considering new instructional strategies tailored to the online teaching environment, such as creating a conducive environment for using online teaching tools and strategies related to checking the online teaching environment. However, for statements of learning objectives, stimulating motivation, and wrapping up, most of the pre-service science teachers predominantly utilized teaching strategies from traditional face-to-face classes, especially those involving the presentation of visual materials through online tools. Student-centered approaches were rarely implemented in stimulating motivation or wrapping up. These findings imply that one semester of exposure to the utilization of online teaching tools may be insufficient in teacher education. Thus, there is a need for a continuous and expanded educational program on the utilization of online teaching tools as part of pre-service teacher education.

The purpose of this study is to confirm the effect of recording online classes and real-time video classes on other behaviors, lecture satisfaction, and lecture flow in during the COVID-19 period. Data were collected and analysis using a structured questionnaire from May 20th to June 4th in 2021 for 550 nursing students in the D University. As a result of the study, it was found that there were more others behaviors in record online classes than in real-time online classes (t=-2.00, p=.046), lecture satisfaction(t=-1.54, p=.124) and lecture flow in real-time online classes it was higher in the record online classes (t=-.63, p=.529), but it was not statistically significant. However, the 2nd year students who participated in the two types of online classes showed statistically significantly higher lecture satisfaction (t=13.55, p=.000) and lecture flow(t=4.48, p=.004). And 4 th grade students of others behaviors was statistically significantly lower (t=4.68, p=.003). In the multiple regression analysis, the main factor affecting lecture flow was lecture satisfaction, and the explanatory power of the model was 55.1% in record online classes (F=128.49, p <.01), and in real-time classes 47.2%(F=77.24, p<.01). In the future, research should be conducted to confirm the difference between the two types of online classes of the same instructor and the difference in other things, lecture satisfaction, and class commitment that appear after applying learner-centered learning.

The aim of this study is to identify the learning performance of online classes using problem-based learning(PBL) for clothing and textiles majors in college with the increased use of online learning tools after the COVID-19 pandemic. In order to achieve this goal, the PBL was developed and applied to the 'Fashion Marketing and Merchandising' class conducted in real-time online at University in North Chungcheong Province, Korea for four weeks. After a four-week PBL class, a survey was conducted on 35 students in the 'Fashion Marketing and Merchandising' class and the 35 completed questionnaires were used for analysis. The measurement tools of this study were self-directed learning, cooperative learning ability, problem-solving ability, and learning achievement regarded as an important learning effect in PBL class. In addition, students' self-reflective essays were also analyzed to examine the educational effect of PBL applying online classes. As a result of this study, bivariate correlations among the four variables, students' self-directed learning, cooperative learning ability, problem-solving ability, and learning achievement were significantly positive. Furthermore, the results of multiple regression analysis showed that the three independent variables had significant effects on students' perceived learning achievement, in the order of cooperative learning ability, self-directed learning, and problem-solving ability. The students' self-reflective essays indicated that problem-based learning worksheet was helpful for identifying problems, and clarifying what they already and what they need to study more. Based on this study, it could be recommended that online class applying PBL could contribute to the improvement of student's learning performance.

급격하게 증가하는 온라인 수업 환경에서 원격으로 학생들의 집중도를 파악하는 것은 중요하다. 집중도를 측정할 수 있는 시스템이 필요하지만 아직까지 실시간으로 정확하게 수업 집중도를 파악할 수 있는 알고리즘이 제안되고 있지 않고 있다. 따라서, 우리는 이러한 문제를 해결하기 위해 최근 발전하는 딥러닝 네트워크와 이에 기반한 시선 추적 알고리즘을 동시에 활용한 수업 집중도 추정 프레임워크를 제안한다. 결과적으로, 이를 통해 학생들의 집중도를 실시간으로 정확하게 측정하여 온라인 수업 환경 개선에 기여한다.

비대면 프로그래밍 수업에서도 대면 수업에서와 유사한 학습 실재감을 느낄 수 있는 수업 방법을 모색하기 위해, 2020학년도 1학기부터 2년에 걸쳐 실시간 화상수업과 미리 제작된 동영상 콘텐츠를 제공하는 온라인 콘텐츠 수업 방법을 순차적으로 적용해보았다. 두 방법의 공통점은 중요한 단원을 공부하는 4주 동안은 플립러닝을 적용하여 예습 동영상을 제공하고 본 수업은 실시간 화상수업으로 진행하면서 예습확인 퀴즈를 실시하고 심화수업으로 운영하였다. 각 수업 학기말에 학생들을 대상으로 5점 척도 방식의 만족도 조사를 실시하여 수업 내용의 이해도, 수업에 대한 흥미도 그리고 수업 참여의 적극성에 대한 학습 효과를 비교해보았다. 그 결과, 세 가지 학습 영역 모두 실시간 화상수업 방식에 참여한 학생들의 만족도가 높은 것으로 분석되었다.

The purpose of this study is to provide fundamental background to improve the quality of teaching and learning performance in online classes by analyzing the students' learning experience aspects on online environment. This study explores the relationship between learning experience and teaching and learning performance according to the online classes types(synchronous/asynchronous class), and identifies the mediation effect of students' perception and attitude toward online classes using Structural Equations Model(SEM). The findings are shown as follows: First, learning experience has positive effect on teaching and learning performance statistically. Second, learning experience has different effect on teaching and learning performance depending on the type of online classes. Specifically, learning experience in synchronous environment has higher influence on teaching and learning performance than in asynchronous environment. On the other hand, perception and attitude toward online classes have greater influence on teaching and learning performance in asynchronous class than in synchronous class. Lastly, the students' perception and attitude toward online classes do not have mediation effects significantly in the relationship between learning experience and teaching and learning performance. The result of this study can be a guide for researcher to approach to teaching and learning performance in online environment of university.
