초록
이 연구는 중학생의 증강현실을 활용한 2인 1조의 소집단 학습에서 나타나는 언어적⋅물리적 상호작용을 분석하였다. 서울 시내 중학교 2학년 학생 12명이 용해도, 녹는점과 끓는점 개념에 대해 증강현실을 활용한 2인 1조의 소집단 학습에 참여하였다. 이 수업은 녹음 및녹화되었으며, 수업이 종료된 후 학생들을 대상으로 반구조화된 면담을 시행하였다. 연구 결과는 개별 진술 단위, 상호작용 단위 그리고물리적 상호작용으로 각각 분석하였다. 개별 진술 단위에서는 정보 설명과 정보 질문의 비율이 높게 나타났다. 상호작용 단위는 단순상호작용, 정교화 상호작용의 비율이 높았다. 정교화 상호작용을 하위 영역별로 보면, 누적형 상호작용의 비율이 높았으며 뒤를 이어 교정형 상호작용이 나타났다. 물리적 상호작용은 활동지를 쓰는 행동과 가상 객체를 관찰하는 행동의 비율이 높았다. 이상의 연구 결과를 바탕으로 중학생 2인의 증강현실을 활용한 소집단 학습을 효과적으로 구성할 수 있는 적절한 방안을 제시하였다.
Abstract
This study analyzed paired middle school students’ verbal and physical interactions in small group learning using augmented reality. Twelve 8th graders were paired to take classes of solubility and melting/boiling points based on augmented reality. These classes were videotaped and recorded. After the classes, all the students participated in a semi-structured interview. The results were analyzed in three sections; individual statement units of verbal interaction, interaction units of verbal interaction and physical interaction. In the individual statement units of verbal interaction, the proportion of information question/explanation was found to be high. In the interaction units of verbal interaction, the proportion of simple interaction was the highest, followed by elaborated interaction. Beneath the elaborate interaction, the proportion of cumulative interaction was found to be the highest, followed by reformative interaction. In the physical interaction, writing a worksheet and gazing at a virtual object were higher. On the basis of the results, effective ways to form a proper environment in small group learning using augmented reality are discussed.
