Abstract
It is the purpose of the study to investigate how high school students understand the concept of carbon cycle according to their spatial perception ability. For this, a total of 30 male students and 33 female students, who belong to the science course of the 2nd grade at a general co-education high school located in a megalopolis of Korea and have finished the class of Earth Science I in the first semester, took part in the spatial perception ability test, and four male students and four female students were selected as members of two groups : one group of higher spatial perception ability and the other group of lower spatial perception ability, and they agreed to participate in the study and have got the test of the carbon cycle concept. The results are as followings. It was found that the students who had higher spatial perception ability recorded more scores in the carbon cycle concept, state change concept, and process concept at the factor of word association and the carbon cycle concept, state change and process concept at the factor of drawing than those who had lower spatial perception ability. Connecting link used in the systemic viewpoint was disclosed like this in the factor of causal map of those who had higher spatial perception ability : one student 2 and another one student 1 and the other two students 0 : and in the factor of drawing three students 1 and the other 0 ; But nothing was found in the factors of causal map and drawing of those who had lower spatial perception ability. In addition, it was also found that those students who had higher spatial perception ability, when compared with those students who had lower spatial perception ability, have understood the fact that carbon moves through the interaction of the earth system's lower parts; Three students, who showed higher spatial perception ability, had a low level of systemic thinking concept, and one student who had higher spatial perception ability and four students who had lower spatial perception ability did not have a systemic thinking concept.
본 연구의 목적은 공간지각능력에 따른 고등학생들의 탄소 순환 개념을 알아보고자 하는 것이다. 이를 위하여 광역시 소재의 평준화 일반계 남녀공학 S고등학교 학생들 중 2학년 1학기에 지구과학 I을 이수한 자연계열 남학생 30명과 여학생 33명을 대상으로 공간지각능력 검사를 실시하고 공간지각능력 상 하 두 집단의 학생들 중에서 본 연구 참여에 동의한 남학생 4명과 여학생 4명을 대상으로 탄소순환 개념 검사를 실시하였다. 본 연구의 결과, 공간지각능력이 높은 학생들은 공간지각능력이 낮은 학생들 보다 단어연상에서 탄소 순환 개념, 상태 변화개념, 과정 개념이 더 많았으며 그림 그리기에서 탄소 순환 개념, 상태 변화와 과정 개념도 더 많은 것으로 나타났다. 시스템적 관점에서 사용된 연결고리는 공간지각능력이 높은 학생들의 인과지도에서 1명이 2개, 1명이 1개, 2명이 0개로 나타났고 그림 그리기에서 3명이 1개, 1명이 0개로 나타났으며 공간지각능력이 낮은 학생들의 인과지도와 그림 그리기에서는 전혀 나타나지 않았다. 공간지각능력이 높은 학생들은 공간지각능력이 낮은 학생들에 비해 지구시스템의 하위영역의 상호작용으로 탄소가 이동하는 것을 이해하고 있었다. 공간지각능력이 높은 3명의 학생들은 낮은 수준의 시스템 사고 개념이 있었으며 공간지각능력이 높은 학생 1명과 공간지각능력이 낮은 학생들 4명은 시스템 사고 개념이 없었다.
