This study surveyed 2nd graders of B high school and 1st graders of A university in Gyeongnam on factors such as behavior control and interaction in non-face-to-face classes, easy or difficult concepts presented in chemistry I and general chemistry textbooks. Based on the results of the survey, the effect of changes in the difficulty level of concepts presented in chemistry I and general chemistry and changes in class types (face-to-face and non-face-to-face) on students' academic achievement by level was compared and analyzed. In the face-to-face class, the average score between the first and second semesters was similar according to the change in the difficulty of the concepts presented in chemistry I and general chemistry. In the non-face-to-face class, the average score of chemistry I in the second semester was quite low, and the average score of general chemistry was rather high. In non-face-to-face classes, the average score of chemistry I in the second semester of low-level students was significantly lowered due to changes in the difficulty of the concept and changes in class types on academic achievement by level. In the case of 10% of students at the lower level, the academic achievement of chemistry I decreased in both the second semester regardless of the changes in the difficulty level of concepts and the changes in class types.

코로나 팬더믹으로 인한 비대면 수업은 지속적인 운영을 통해 개선·발전되었다. 2022학년도부터 대면수업으로 전환되면서 온라인 플랫폼에 대한 적응력이 높아지고, 비대면 수업 경험이 축적된 학습자들을 위한 대면 수업의 변화가 필요하게 되었다. 본 논문은 프로그래밍 수업에서 비대면 방식과 대면 방식에 대한 경험이 있는 학습자들의 수업방식에 따른 만족도 및 의견을 조사·분석함으로써 서로 다른 두 방식의 장점을 활용한 수업모델을 모색하는데 필요한 학습자 의견 도출에 그 목적이 있다. 조사 결과, 학습자들은 대면 수업을 선호하나 비대면 학습경험이 많을수록 대면 수업에서의 단점을 비대면 수업을 통해서 해소할 수 있는 부분이 있음을 인지하고, 비대면 방식을 대면 수업에 활용하는 것을 긍정적으로 생각하는 것으로 나타났다. 이를 통해 향후 대면 프로그래밍 수업에서 비대면 방식을 결합한 하이드리드 방식의 수업 운영을 통한 수업 효과 증진 모델이 필요한 것으로 사료된다.

COVID-19 (Corona Virus Desease-19)로 인해 2020년에는 국내 모든 대학이 비대면 수업을 진행하는 상황이었다. 본 연구는 이러한 비대면 수업하에서 특히 실습수업이 중요한 공과대학생들의 경우 어떤 요인들이 학업 성취도에 영향을 미치는가를 연구하고자 하는 것이다. 본 연구를 위해 D대학의 공과대학생들 대상의 학습성취도 관련 설문문항을 이용하여 회귀 모델과 경로 분석을 결합한 구조 방정식 모형을 적용하고 본 연구에서 정의한 통계적 연구가설의 타당성을 검증하고자 한다. 또한 본 연구를 통해 지속화 되고 있는 비대면 수업에서, 특히 공과대학에서 고려해야 할 요소들이 무엇인지를 제안하고자한다. 조방정식의 최적의 모형 결과 학습성취도에 직접적인 영향을 주는 요인으로 질의 및 피드백 그리고 이러닝 시스템으로 나타났다. 또한 이 두 요인은 이론수업과 실습수업이라는 매개변수를 통해 학업 성취도에 간접적으로도 영향을 주고 있음을 확인할 수 있었다.

Objective: In the present study, to determine the extent of academic stress and pain from sitting for a long time, we will use a questionnaire to examine the effects of non-face-to-face stress and back pain on college students who have conducted non-face-to-face lectures. Design: Survey research Methods: A questionnaire was conducted using Naver foam to identify academic stress, attitude and time to listen to lectures, and the extent of back pain for college students who are experiencing non-face-to-face lectures. Outcome measures include the scale of academic stress (SAS), the Numeric rating scale (NRS), the Oswestry Disability Index (ODI Korea version) was implemented. The difference in academic stress was analyzed by t-test and one-way ANOVA, and the correlation between academic stress and back pain was analyzed using the Spearman correlation coefficient. In order to examine the academic stress, consistency, and stability, the reliability of the academic stress items was measured by examining the reliability with the Cron-Bach alpha coefficient. Allstatistical significance levels were α=0.05. Results: According to the general characteristics of the subject, there were no statistically significant results compared to gender (P<0.05), but the higher the grade, the higher the stress index, the higher the level of pain. Conclusions: This study confirmed that non-face-to-face lectures caused by COVID-19 have increased academic stress and the resulting increase in back pain in college students.

In this study we conducted a research regarding the effect on learning immersion and perception of the learning environment by learning presence of students in the Department of aeronautical science and flight operation in the context of non-face-to-face lectures caused by COVID-19. The relationship between learning presence (cognitive presence, emotional presence, and social presence) and learning commitment showed a high correlation. The learning immersion was also found to increase when cognitive presence, emotional presence, and social presence increased in multiple regression analysis to find out the effects of cognitive presence, emotional presence, and social presence, which are sub-factors of learning presence. The advantage of non-face-to-face classes was to be the ease of learning, and the disadvantage of non-face-to-face classes was the most difficulty of the learning process in the content analysis of the non-face-to-face class environment.

This study is a questionnaire about the lesson environment that radiation major students prefer in a non-face-to-face live online lesson environment for a total of 133 students, 65 second graders and 68 third graders who are enrolled in the department of radiology at a university located in the Seoul metropolitan area. And checked the satisfactory level by grade. The questionnaire consists of three categories: 1st real-time non-face-to-face lectures, 2nd professor lectures, and 3rd corona lectures. A total of 14 questions, with multiple choice and descriptive response methods. As an evaluation method, in the case of a multiple-choice question, the average was calculated using a 5-point Likert scale. As a result of conducting the independent sample T-test of the SPSS program, the response by grade was P > 0.05, and no significant result was shown by the contents of the questionnaire survey of the second grade. As for the lecture method of the department of radiology after the end of Covid-19 virus, it is better to promote face-to-face lessons in radiation training subjects and non-face-to-face real-time education in subjects centered on radiation theory.

Objectives: To investigate the perceived quality of classes, academic emotions, and learning achievement levels associated with the non-face-to-face classes of health science students, and to analyze the factors related to class satisfaction. Methods: Using a questionnaire, 238 health science students were surveyed regarding the quality of classes, academic emotions, and learning achievement levels. Factors related to calss satisfaction were analyzed using stepwise multiple regression. Results: Lecture types that the students were most satisfied with were 'video lectures using PPT' and 'recorded lectures provided by LMS', while 'real-time video lectures' were scored the lowest (p=0.005). Factors affecting non-face-to-face class satisfaction were perceived achievement (β=0.425, p<0.001), learning content (β=0.265, p<0.001), learning emotion (β=0.171, p<0.001), and learning environment (β=0.137, p=0.012). The adjusted explanatory power for this model was 63.9%. Conclusions: To increase the satisfaction of health science students with non-face-to-face classes, it is necessary to prepare an institutional foundation and to develop an educational program that can increase perceived achievement.

이 연구의 목적은 초등 예비교사를 대상으로 비대면 수업 자료 만들기 활동을 실시한 후 영상 자료 제작에 대한 인식과 과학 교수 능력에 미치는 효과를 알아보는 것이다. 이 활동은 초등 예비교사들이 탐구를 수행하고 관련 과학 개념을 이해하고, 교과서를 분석한 후 영상 자료를 제작하는 과정과 동료들이 제작한 영상을 시청하는 과정으로 구성되었고, 8주 동안 89명의 예비교사들에게 실시되었다. 이 활동이 종료된 후 초등 예비교사들에게 영상 자료 제작에 대한 인식과 과학 교수 능력에 미치는 효과를 알아본 후 그 결과를 분석하였다. 비대면 수업 자료 제작과 시청 과정에서 초등 예비교사들은 영상 자료 제작에 대해 교수-학습, 영상 제작, 정서 및 태도 측면에서 긍정적으로 인식하는 것으로 나타났다. 그리고 초등 예비교사들은 이 활동을 통해 과학 교수 역량이 향상되었고, 이 활동에 대해 매우 만족하는 것으로 나타났다. 그러나 학습자의 자기 결정권 배제, 다양한 의사소통 통로 부족, 자료내용의 오류 등 아쉬운 점도 언급하였다. 이러한 문제점을 해결한다면 비대면 수업도 하나의 좋은 수업 형태가 될 수 있음을 시사한다.

This study surveyed 233 students who experienced non-face-to-face and face-to-face classes in "86 first-year, 76 second-year, and 71 third-year students" enrolled in the radiology department of universities in the Seoul metropolitan area. The main question of questionnaire consisted of a total of 14 questions, including online lectures and face-to-face lectures, use of electronic devices during classes, students' thoughts on flipped learning methods, and finally, whether it was helpful for students who were unable to participate in face-to-face classes due to COVID-19 to take classes online. The responses were composed optional to select the content of the questionnaire and descriptive to obtain open thinking from students. Comparing the significance level of responses of second and third graders based on the first graders, p>0.05 for second graders and p<0.05 for third graders, showing a significant difference in satisfaction with third graders who were greatly damaged by COVID-19 and freshmen. In conclusion, even in a situation where face-to-face lectures can be conducted, it is considered beneficial for students to conduct online lectures and face-to-face lectures according to the method of the major subject.
