A Case Study of Middle School Students' Conceptual Change on the Concept of Force: Conceptual Ecological Approach

  • 발행 : 2007.10.30

초록

이 연구에서는 힘 개념에 대한 중학생의 개념생태 요소를 탐색하고 개념변화의 사례를 살펴보는 데 그 목적이 있었다. 연구는 질적 방법을 사용하였으며, 수업관찰과 면담으로 수행되었다. 연구 참여자는 중학생 11명으로 여학생 7명과 남학생 4명이었다. 면담은 힘단원의 수업 시작 전 사전 검사와 2차레 개별 심층 면담으로 이루어졌다. 수집된 자료는 모두 전사되고 해석적으로 분석되었다. 연구 결과는 두 부분으로 기술되었다. 첫째, 연구 참여 학생들의 힘 개념을 구성하는 개념생태는 크게 인식론적 확신근거(일방향 및 상호작용적 설명 일관성), 비유(속성, 작용), 형이상학적 신념(인간중심의 존재론, 물활론, 인과적 추론, 혼합형), 과거 경험의 네 범주로 분류할 수 있었다. 둘째, 학생들의 개념변화의 대표적인 유형으로, 개념의 안정 상태와 개념변화로의 과도기 상태를 보여주는 사례를 제시하였고, 개념생태의 특정을 살펴보았다. 이 연구의 결과는 중학생의 힘 개념의 위치와 변화 가능성에 대하여 개념생태를 통하여 구조적이고 상호 연관적 이해를 추구한다는 점에서 기존 연구 결과를 통합적 관점에서 볼 수 있도록 해 준다. 뿐만 아니라 개념생태의 진화적 관점으로 개념 변화를 추구해야 할 것으로 시사한다.

This study explored the types of conceptual change of 'force' within middle school students' conceptual ecologies. This qualitative study was implemented with the use of classroom observations and two interviews with the participants. 11 middle school students (7 females and 4 males) joined in this study. The interviews with the participants were conducted individually before and after the 'force' unit. The collected data were all transcribed and analyzed interpretively. The results of this study consisted of two parts. First, the participants' conceptual ecologies of 'force' were categorized into 4: epistemological commitments (fixed or interactional explanatory consistency), analogy (attribute, working), metaphysical beliefs (people-oriented ontology, animism, causationism, mixed), and past experiences. Second, two representative cases including 'stable' and 'transitional' states were explained based on the interactions within their own conceptual ecologies. We can see students' conceptions with the integrated perspective in the sense that this results tried to get contextual and interactional understandings of the status of the conception and the possibilities of conceptual change. In addition, it implied that conceptual change research should have the perspective of conceptual ecology evolution in the future.
