초록

이 연구에서는 증강현실을 활용한 협력적 과학 개념학습에서 나타나는 학생들의 언어적 상호작용과 물리적 상호작용을 심층적으로 조사하였다. 3개의 소집단으로 구성된 고등학교 1학년 학생 12명이 연구에 참여하였다. 이들은 화학 결합 개념 이해를 목표로 개발된 스마트 기기 기반의 증강현실 어플리케이션을 활용한 수업에 참여하였다. 학생들의 수업 과정은 녹음 및 녹화하였으며, 반구조화된 면담을 실시하였다. 연구 결과, 언어적 상호작용 중 개별 진술 단위에서는 정보 질문과 정보 설명 및 방향 질문과 방향 설명에 관한 진술의 비율이 높았고, 상호작용 단위에서는 교정형 및 누적형 상호작용의 비율이 높았다. 학습 진행에 관한 개별 진술 및 상호작용의 비율도 높게 나타났다. 학생들의 물리적 상호작용은 유의미한 언어적 상호작용 없이 단독으로 이루어진 경우가 가장 많았다. 학생들이 지식 구성 언어적 상호작용을 하며 물리적 상호작용을 할 때는 가상 객체를 응시하거나 활동지 관련 활동을 하는 비율이 높았던 반면, 물리적 상호 작용만 수행하거나 운영 관련 언어적 상호작용을 하며 물리적 상호 작용을 할 때는 증강현실의 마커의 조작과 관련한 다양한 탐색적 활동이 주로 나타났다. 연구 결과를 바탕으로 과학 교과에서 증강현실을 활용한 협력적 개념학습이 효과적으로 이루어지기 위한 방안을 제안하였다.

This study investigated verbal and physical interactions which appeared in collaborative science concept learning using augmented reality. Twelve 10th grade students participated in this study. After being organized into three four-member small groups, they participated in classes using smart device-based augmented reality application developed for the understanding of the chemical bonding concept. Their class activities were audio- and video-taped. Semi-structured interviews were also conducted. The results revealed that within individual statement units of verbal interaction, the proportions of information question/explanation and direction question/explanation were found to be high. Within interaction units, the proportions of reformative and cumulative interaction were relatively high. The proportions of progress were also found to be high within both individual statement units and interaction units of verbal interaction. Students' physical interactions were mainly conducted without meaningful verbal interactions. When their physical interactions were accompanied by knowledge construction-related verbal interactions, the proportions of gazing virtual objects and worksheet-related interactions were high. In contrast, various exploratory activities related to the manipulation of markers mainly appeared when they conducted physical interactions only, or when their physical interactions were accompanied by management-related verbal interactions. On the bases of the results, effective methods for collaborative concept learning using augmented reality in science education are discussed.
