초록

본 연구는 멀티미디어 학습에서 이미지, 목소리, 메시지 스타일(개인화) 등 사회적 단서의 수준을 차별적으로 처리한 네 가지 유형의 콘텐츠들이 학습성과에 미치는 영향을 탐색하는데 있다. 이를 위해 동일한 내용과 분량의 한국지리 강의를 첫째, 강사출연 동영상(강사의 이미지, 목소리, 메시지 스타일) 둘째, 칸스타일 동영상(목소리, 메시지 스타일) 셋째, 아나운서 내레이션 동영상(메시지 스타일) 넷째, 파워포인트 등 네 가지 종류의 학습 콘텐츠로 제작하여 학습용 태블릿에 저장하여 검사도구로 사용하였다. 고등학교 1학년 60명의 참가자들은 사회적 단서가 수준별로 처치된 콘텐츠 유형에 따른 4개의 집단에 무선할당 되었고 50분간 통제된 실험 상황에서 연구가 실시되었다. 실험 결과 콘텐츠의 사회적 단서는 수준별 제시 여부에 따라 학습만족도(F=5.178, p=.003)와 학업성취도(F=3.457, p=.022)의 집단간 차이에서 각각 통계적으로 유의미하였다. 실험을 통해 본 연구는 첫째, 사회적 단서의 수준이 높을수록 학습만족도와 학업성취도가 높다는 사실을 검증하였으며 둘째, 다양한 수준의 사회적 단서를 포함하고 있는 멀티미디어 콘텐츠 학습에서 메시지 스타일을 통한 개인화의 원리가 매우 중요하게 작용하고 있음을 확인하였다.

Abstract

This study aims to observe how social cues influence learners’ satisfaction and learning performance in the process of learning contents which contain different levels of social cues such as image, voice and style of message (individualization). To achieve a significant statistical result, this study assigned four types of experimental groups and studied their differences. There are four types of video contents according to the level of social cue included; the first type consists of the image and voice of a lecturer and a style of the message which are high-level social cues. The second type has a voice of a lecturer and a style of message, and the third one is in a third-person perspective where a voice of a lecturer is dubbed by an announcer’s narration. And the last type only consists of PowerPoint contents without any social cues. 60 first year high school students from a major Korean city participated in this experiment. They were randomly divided into four different groups which were classified according to the contents with different levels of social cues. After the participants performed learning under the controlled experiment for 50 minutes with their own tablet PC, they answered questionnaires. The result showed a statistically significant difference between the groups in terms of learner’s learning satisfaction (F=5.178, p= .003) and learning achievement (F=3.457, p= .022). Learner’s learning satisfaction was observed highest in the video where a lecturer is present, and it was followed by Khan style video, PowerPoint, and announcer narration, accordingly. Based on the results of the experiment, first this study could verify that both learner’s satisfaction and learning achievement are proportional to the level of social cues, and second, identify that the principle of individualization through the style of message in multimedia contents learning including various levels of social cues plays a significantly important role.
