초록
아동들이 형식 교육을 받기 이전에도 수학을 이해하고 있으며 학습능력에 따라 이런 이해에 차이가 있을 것이라는 가정을 검증하기 위해서 본 연구를 실시하였다. 이를 위해서 초등학교 1, 2, 3 학년 학생들이 분수를 학습하기 전에 형성하고 있는 분수에 대한 개념 그리고 학년 및 학습능력에 따른 분수 개념들의 이해 정도를 알아보았다. 학습능력은 추론능력 및 학업성취도를 조합한 것으로 조작적 정의를 하였으며, 학습능력에 따라 학년별로 6명씩(상, 중, 하 각 2명)을 연구 대상으로 선정하였다. 분수개념에 대한 과제를 개발하고, 구조화된 면담을 실시하였으며, 질적 분석을 위해 비디오 녹화, 면담 프로토콜, 관찰 등을 통해 아동의 반응을 수집하고, 아동들의 반응은 유형에 따라 분석하였다. 분석 결과로부터 다음과 같은 결론을 얻을 수 있었다. 아동들은 형식 교육을 받기 이전에 분수에 대한 다양한 비형식적 지식을 형성하고 있었으며, 이 중에는 분수의 형식적 학습에 바탕이 될 수 있는 것과 오개념을 유도할 수 있는 것이 존재하였다. 또한 아동이 형성한 비형식적 지식에는 학년, 학습 수준에 따라 차이가 존재하였다. 이는 비형식적 지식이 다양한 학습 경험과, 일상생활의 경험에 영향을 받기 때문인 것으로 분석되었다.
Abstract
Based on the thinking that people can understand more clearly when the problem is related with their prior knowledge, the Purpose of this study was to analysis students' informal knowledge, which is constructed through their mathematical experience in the context of real-world situations. According to this purpose, the following research questions were. 1) What is the characteristics of students' informal knowledge about fraction before formal fraction instruction in school? 2) What is the difference of informal knowledge of fraction according to reasoning ability and grade. To investigate these questions, 18 children of first, second and third grade(6 children per each grade) in C elementary school were selected. Among the various concept of fraction, part-whole fraction, quotient fraction, ratio fraction and measure fraction were selected for the interview. I recorded the interview on digital camera, drew up a protocol about interview contents, and analyzed and discussed them after numbering and comment. The conclusions are as follows: First, students already constructed informal knowledge before they learned formal knowledge about fraction. Among students' informal knowledge they knew correct concepts based on formal knowledge, but they also have ideas that would lead to misconceptions. Second, the informal knowledge constructed by children were different according to grade. This is because the informal knowledge is influenced by various experience on learning and everyday life. And the students having higher reasoning ability represented higher levels of knowledge. Third, because children are using informal knowledge from everyday life to learn formal knowledge, we should use these informal knowledge to instruct more efficiently.
