초록
본 연구의 목적은 무게 재기 단원을 지도한 교사가 겪는 어려움과 무게 재기 단원을 학습하는 학생들이 겪는 어려움을 탐색하는 데에 있다. 이를 위해 교사 대상으로는 설문지, 면담, 자기반성성찰지를, 학생 대상으로는 설문지, 단원평가지, 면담을 통하여 자료를 수집하였으며 반복적으로 자료를 검토하고 범주화 하였다. 분석한 자료는 과학교육 전문가 2명과 함께 검토하였다. 연구결과 교사들이 겪는 어려움은 교사들의 절차적 지식의 부족, 교육과정의 연계성 부족, 충분하지 못한 수업환경, 그리고 학생들의 조작능력 미숙으로부터 나타났다. 학생들이 겪는 어려움은 오개념의 발생, 이해하기 어려운 개념, 조작 능력 미숙, 수학적 능력의 부족, 실제에 원리 적용의 어려움, 문제해결능력 부족으로부터 나타났다. 그리고 교사들은 학생들이 실험부분에서 더 어려움을 겪는다고 인식을 하였으나 학생들은 개념을 이해하는데 더 많은 어려움을 겪는 것으로 나타났다.
Abstract
The purpose of this study is to investigate the difficulties of teachers and students on the unit about 'measuring weight.' In this research, we have acquired data about teachers through survey, interview, and self-reflection journals, at the same time we have collected information on the students through survey, assessment test, and interview. We have extracted the difficulties from analysis with constant comparison method. In addition, we have analysed the curriculum of science and mathematics to know the leaning sequence. The analysis had been checked up by experts in science education. The result of the study is as follows: The difficulties of teachers are from the lack of teachers' descriptive knowledge, disorder of conceptual hierarchy in the curriculum, poor experimental instruments, and low psychomotor skill of students. The difficulties of students are from common misconceptions, opaque concepts, lack of manipulation skill, insufficiency of mathematical ability, difficulty of application of principles to the real situation, and lack of problem-solving ability. In addition, teachers have recognized that students face more difficulties in experiment class, while students think that they face more difficulties in conceptual understanding class.
