초록

본 연구에서는 PISA 검사결과를 토대로 온실효과에 대하여 우리나라의 만 15세 학생들이 지니고 있는 전형적인 학생개념의 유형을 분석하였다. 온실효과에 대한 기존 선행연구에서 밝혀진 학생들의 대안적인 개념에 비추어 볼 때, 현재 우리나라의 만15세 학생들의 온실효과에 대한 이해 수준을 온실효과의 자연적 요인과 인위적 요인으로 나누어 분석하고, 온실 효과를 초래한 원인에 대한 학생들의 오개념 유형을 살펴보았다. 이산화탄소 이외에 지구의 온도 상승에 기여하는 요인들 우리나라 학생들은 프레온 가스, 매연, 수증기, 메탄 등을 지적하였다. 또한 많은 학생들이 온실효과와 오존층 파괴가 인과관계를 지니고 있는 것으로 파악하고 있음을 알 수 있었다. 과학과 교수 학습에 얻을 수 있는 시사점을 도출하였다.

This study investigated Korean fifteen-year-olds' (mis)conceptions on the greenhouse effect based on the PISA results. Based on previous studies on students' ideas about the greenhouse effect, Korean students'understanding of the natural factors and human-induced factors of the greenhouse effect were analyzed. Students' misconceptions about causes of the greenhouse effect were also examined. In addition to CO2, Students mentioned CFCs, atmospheric pollution, water vapor and methane as greenhouse gases. Many students indicated that the greenhouse effect and ozone depletion have a causal relationship. Teaching implications of the misconceptions were also discussed.
