초록
이 연구에서는 증강현실을 활용한 소집단 학습에서 나타나는 중학생의 지식 형성 담화의 유형과 지식 형성 과정을 탐색하였다. 서울시소재의 남녀공학 중학교 2학년 학생 8명이 증강현실을 활용하여 용해도 개념, 끓는점과 녹는점 개념에 대한 소집단 학습에 참여하였다. 수업은 2차시에 걸쳐 이루어졌으며 모두 녹음 및 녹화하였다. 이후, 연구에 참여한 학생들은 반구조화된 면담에 참여하였다. 지식 형성담화의 유형에서 지식 공유와 지식 구성의 비율은 비슷하게 나타났다. 지식 공유에서는 기초 수준의 토의, 증강현실의 핵심 요소 확인의순으로 나타났고, 사전 지식의 회상은 거의 나타나지 않았다. 지식구성에서는 심화 수준의 토의가 가장 높았고, 그다음으로 다른 수준에서의 공유 및 비판과 현재의 설명 수준을 넘어서려는 노력이 나타났으며, 두 요소의 비율은 유사하였다. 지식 공유의 하위 요소인 기초 수준의 토의와 증강현실의 핵심 요소 확인은 지식 구성의 하위 요소인 현재의 설명 수준을 넘어서려는 노력과 다른 수준에서의 공유 및비판으로 발전되어 나타났다. 지식 형성 과정을 시각화했을 때, 모든학생의 누적 영향 값 그래프는 우상향하는 형태로 나타났지만, 소집단별로 두 학생의 누적 영향 값은 차이가 나타나는 경우가 있었다. 이상의 연구 결과를 통해 증강현실을 활용한 중학생의 소집단 학습촉진 방안을 제시하였다.
Abstract
This study analyzed the types of knowledge building discourse and knowledge building processes in small group learning using augmented reality. Eight 8th grade students took classes using augmented reality in solubility, boiling and melting points. These classes were carried out twice and all the classes were videotaped and recorded. Every student participated in a semi-structured interview. In the types of knowledge building discourse, the proportion of knowledge sharing and knowledge construction was similar. Beneath the knowledge sharing, the proportion of introductory level discussion was higher than identifying key elements of augmented reality. Recalling existing knowledge rarely appeared. Under the knowledge construction, the proportion of advanced level discussion was the highest and the proportion of sharing and critiquing ideas at a different level and efforts to rise above current levels of explanation was similar. The introductory level discussion and identifying key elements of augmented reality were developed into efforts to rise above current levels of explanation and sharing and critiquing ideas at a different level. Visualized results of knowledge building processes showed all the students’ graph drew an upward curve, though cumulative number of impact value was different by each student. As a result of the study, effective ways of improving small group learning using augmented reality are discussed.
