본 연구의 목적은 연소 모델의 사회적 구성 과정에서 나타나는 소집단 활동의 특징을 살펴보는 것이었다. 본 연구를 위해, 중학교 2학년 1개 반을 대상으로, 8개의 소집단으로 나누고, 각 소집단이 3차례의 논의를 통해 연소에 관한 모델 구성을 하도록 MIS과정에 따라 2차시로 수업을 구성하였다. 수업 내용 및 학생과 학생, 학생과 교사의 담화 내용은 비디오 촬영 및 녹음을 한 후 전사하여 분석하였다. 분석 결과, 소집단별 모델 생성에서 협력 유형은 비협동형인 나열형과 의존형, 협동형이 있었으며, 모델 생성과정을 경험함에 따라 2개의 소집단을 제외한 6개의 소집단이 협동형으로 발달하였다. 또한 연소에 관한 모델의 발달을 살펴본 결과, 플로지스톤설에서 산소설로 발전하는 과정에서 나타난 과학자들의 사고와 비슷한 사고 발달이 보였으며, 이를 통해 연소현상에 대한 이해가 발전되고 현상을 설명할 수 있는 모델로 발전하는 것이 나타났다. 협동형 소집단 중 구성원간의 존중, 리더의 민주적인 태도가 높을수록 목표 모델 도달 횟수가 높았다. 또한 성공적인 모델 생성을 위해서는 구성한 모델에 대한 소집단 내, 소집단 간 비판적 검토가 필요하며, 교사의 도움을 모델 수정과 평가에 활용할 줄 아는 능력 또한 요구됨을 알 수 있었다. 이 연구는 과학 모델의 사회적 구성 과정이 학생들의 현상에 대한 이해를 높이는 과학 탐구의 한 방법으로서 교육적으로 의미가 있으며, 모델링 수업 중 교사의 역할에 대한 시사점을 얻는데 그 의의가 있다.
In this study, we explored the development of scientific model through the social-construction process on "combustion." Students were 8th graders from one middle school class. Each student engaged in small group discussions three times and made a group model on combustion. Discourses between peers and teacher were videotaped, audiotaped, and transcribed. The results show that the small groups constructed an initial concept: 'Conditions of combustion', which they then evaluated and revised the initial concept through combustion experiment. Following the discussions, some small groups evaluated their model and made a revised model. Then, the small groups compared various models and constructed a scientific model through consensus within the small group and as a whole class. Finally, students kept revising their model to 'Burning needs oxygen.' This tells us that the social construction process of scientific model made a meaningful role to build scientific model through diverse discussion between the students and their teacher, although they have had some difficult process to reach the final consensus. The data also showed some group features: the members were open to other's ideas. They analyzed the differences between their own ideas from others and revised their model after the whole class discussion. Lastly, they showed the tendency to make a good use of teacher's guidance. This study implies the importance of having social interaction process for students to understand the scientific model and learn the nature of scientific inquiry in class.
