Abstract

In this study, we applied the flipped-classroom to the general chemistry experiment lecture of the domestic university with strong teacher-led, and explored the effects and possibilities of the course. For this purpose, 30 students who were enrolled in the Science Education Department of the College of Education in the metropolitan area were randomly assigned to two groups, namely, the flipped-classroom group and the traditional class group. Then, we developed a general chemistry experiment lessons based on the flipped-classroom along with visual materials and we applied the lessons for 15 weeks. After all the classes, we conducted a survey to see the students' perception of the general chemistry experiment lecture by flipped classroom. As a result of analysis, the students of the flipped-classroom group were more positive than the students of the traditional class group in terms of the usefulness of the class activity, the importance of each activity element for the successful learning, the learning level, and the intention for another lesson. As a result of analyzing students' perceptions in terms of general chemical experiment activities such as conducting experiments or writing reports and understanding the contents of experiments, the average score of the flippedclassroom group was higher than the traditional class group, and the main cause of this result was the video material provided by prior learning activities. In addition, as a result of analyzing students' perceptions in terms of interactions and self-directed learning in class, the average score of the flipped-classroom group was generally higher than the traditional class group. In particular, students' interactions and self-directed learning were statistically significant differences between the two groups. And the students' perception of video material was very positive, and it was analyzed that the video that the instructor directly explained experiment theory and method was the most favorite videos of students. We discussed educational implications of these findings.

이 연구에서는 거꾸로 교실을 교사 주도성이 강한 국내 대학의 일반화학실험 강좌에 적용하고, 이를 통해 거꾸로 교실을 적용한 대학 실험 강좌에 대한 효과와 가능성을 탐색하였다. 이를 위하여 수도권 소재의 사범대학 과학교육과에 재학 중인 30명의 학생들을 15명씩 거꾸로 교실 수업 집단과 전통적 수업 집단의 두 그룹으로 각각 무선배치 하였다. 그런 다음, 동영상 자료와 함께 대학에서 적용 가능한 일반화학실험 수업 안을 개발 및 적용하였고, 모든 수업을 마친 후에는 일반화학실험 강좌에 대한 학생들의 인식을 살펴보기 위한 설문 조사를 실시하였다. 일반화학실험 수업에 대한 전반적인 인식 분석 결과, 수업 활동의 유용성, 성공적 학습을 위한 각 활동 요소 별 중요도, 학습 수준, 추후 수강 의향 등의 측면에서 거꾸로 교실 수업 집단의 학생들이 전통적 수업 집단의 학생들 보다 긍정적인 인식을 나타냈음을 알 수 있었다. 실험 수행이나 보고서 작성 등과 같은 일반화학 실험 활동과 실험 내용의 이해 측면에서 학생들의 인식을 분석해 본 결과, 거꾸로 교실 수업 집단의 평균 점수가 전통적인 수업집단의 평균 점수 보다 높았고, 이와 같은 결과의 주된 원인은 담당 강사가 사전 학습 활동으로 제공한 동영상 자료 때문인 것으로 나타났다. 또한 수업 중 상호작용과 자기 주도적 학습 측면에서 학생들의 인식을 분석한 결과, 거꾸로 교실 수업 집단의 평균 점수가 전통적 수업 집단의 평균 점수 보다 전반적으로 높았으며, 특히 학생들 간의 상호작용과 자기 주도적 학습의 수월성은 두 집단 간에 통계적으로 유의미한 차이가 있는 것으로 나타났다. 그리고 동영상 자료에 대한 학생들의 인식이 매우 긍정적이었고, 이 때 학생들이 가장 선호한 동영상은 담당 강사가 직접 실험 이론과 방법을 설명해 주는 동영상이었던 것으로 분석되었다. 이에 대한 교육적 시사점을 논의하였다.
