Abstract

The purpose of this study is to investigate differences in learning flow and teaching presence according to the lecturer's appearance and the lecturer's speech rate. For this experiment, 183 freshman students from Xingtai University in China were selected as subjects of the experiment, and a total of four types of lecture videos were developed to test the lecturer's appearance and their speech rates. Data was analyzed through multivariate analysis of variance. According to the results of the analysis, first, learning flow and teaching presence of groups who experienced the presence of the lecturer appeared were significantly higher than the groups who learned without the appearance of the lecturer. Second, the groups who learned from videos with a fast speech rate showed higher learning flow and teaching presence than the group who learned at a slow speech rate. Third, there were no significant differences in both learning flow and teaching presence according to the lecturer's appearance and speech rate. This result provides a theoretical and practical basis for developing customized videos according to learners' characteristics.

본 연구는 동영상 학습에서 교수자 출연 여부와 교수자 발화속도가 학습몰입과 교수실재감의 효과에 차이를 나타내는지를 실험을 통해 밝히는 것이다. 실험 대상자는 중국 형태대학교 1학년 183명이며, 이들에게 교수자가 출연여부와 발화속도 고저의 4가지 동영상을 학습하도록 한 후, 학습몰입과 교수실재감을 측정하였다. 수집된 자료는 다변량분산분석을 통해 분석하였다. 분석결과 첫째, 교수자가 출연한 동영상을 학습한 집단이 그렇지 않은 집단보다 학습몰입과 교수실재감이 모두 높게 나타났다. 둘째, 교수자의 발화속도가 높은 동영상으로 학습한 집단이 낮은 동영상으로 학습한 집단보다 학습몰입과 교수실재감이 모두 높게 나타났다. 셋째, 교수자 출연여부와 발화속도의 학습몰입과 교수실재감에 대한 상호작용 효과는 유의한 차이가 없는 것으로 나타났다. 이러한 연구결과는 대학 수업에서 효과적인 학습을 위한 강의 동영상을 개발할 때 교수자의 출연여부와 발화속도를 어떻게 설계할 것인지에 대한 이론적·실천적 근거를 제공한다. 즉 가급적 동영상에 교수자가 출연하여 표정, 몸짓과 같은 비언어적 방식으로 사회적 단서를 제시하는 것이 중요하다. 또한 교수자는 동영상에서 약간 빠른 속도로 설명함으로써 학생이 학습에 더 집중하여 몰입하게 할 수 있다. 교수자 출연과 빠른 발화속도는 학습에 몰입하게 하고, 동영상에서 교수행위가 실재로 이루어지고 있다는 느낌을 주게 한다는 것을 시사한다.
