초록

선행 연구에 의하면 많은 교사와 학생들이 원소에 대한 현대적 개념을 가지고 있지 못하고 원자 개념과의 구분도 잘하지 못한다고 한다. 교과서 서술 내용이 그 원인의 하나가 될 수 있으므로 본 연구에서는 해당 중학교와 고등학교교과서의 원소관련 서술 내용을 분석하고자 하였다. 이를 위해 현행 2009개정 교육과정에 의해 출간된 중학교 과학② 교과서 9종과 고등학교 화학I교과서4종을 모두 선정하여 해당 단원의내용을 몇 가지 분석 관점을 설정하여 분석하였다. 그 결과 원소의 정의는 더 이상 분해할 수 없는 물질의 기본 성분으로 되어 있어 거시적 수준의 정의를 하고있는 것으로 나타났다. 그 이후 원자 개념과 비교하여 미시적 수준의 설명이 제시되고 있으나 원소가 원자종이라는설명은 중학교 일부 교과서에만 있었다. 고등학교 교과서는 원소를 기본 성분 대신 기본 물질이라고 표현한 교과서가 일부 있고, 홑원소 물질로서의 원소 개념은 제시되었으나 원자종으로서의 원소 개념은 제시되지 않았다. 따라서원자 개념 도입 이후에는 원소가 원자종의 개념과 홑원소 물질의 개념을 모두 가지고 있음을 교과서에 명확하게 제시할 것을 제안한다.|Previous studies showed that many teachers and students did not know the modern definition of chemical element and they had difficulties distinguishing the concept from that of the atom. One of the reasons for this might be the insufficiency of descriptions for the chemical element in textbooks. In this study, the descriptions for the chemical element in the current secondary school textbooks were reviewed. Nine Science ② textbooks for middle school and four Chemistry I textbooks for high school published based on the 2009 Revised National Curriculum were selected and the contents of the chapters related to chemical element were analysed from several perspectives. The results showed that the definition of chemical element in the textbooks was found to be a macroscopic one; the chemical element is a basic component of matter and cannot be decomposed into simpler matter. The microscopic meaning of chemical element compared to atom was presented afterwards. However, the concept of chemical element as a species of atoms only appeared in a few middle school Science ② textbooks. High school Chemistry I textbooks had only the concept of chemical element as an elementary substance. Some high school Chemistry I textbooks used the expression of ‘basic substance’ instead of ‘basic component’. It is proposed that textbooks present both definitions of chemical element- a species of atoms and an elementary substance- after the atomic concept is introduced.
