这项研究是一项尝试，旨在帮助学生了解越来越多的关于环境和自然资源问题的概念和观点。以下问题得到了解答：“9年级(15-16岁)和12年级(18-19岁)的瑞典学生如何解释温室效应？”，“他们认为减少二氧化碳排放将如何影响社会？”以及“他们如何解释臭氧层耗尽是个问题？”回答这些问题的方法是让学生完成开放式的书面任务。答案中出现了温室效应的五个模型，这些模型或多或少都不完整，但仍具有发展潜力。学生们的回答也表明，他们并不完全理解二氧化碳排放量的大幅减少会带来哪些根本性的社会变化。另一方面，他们非常了解臭氧层的枯竭对人类的危害。对这些发现进行了讨论，包括对教学的启示。(C)2000 John Wiley&Sons，Inc.
This study is an attempt to contribute to the growing body of knowledge about students' conceptions and views concerning environmental and natural resource issues. Answers have been sought to the following questions: "How do Swedish students in grade 9 (15-16 years ord) and grade 12 (18-19 years old) explain the greenhouse effect?", "How do they think reduction of CO2 emission would affect society?" and "How do they explain that the depletion of the ozone layer is a problem?" The method chosen to answer these questions was to give students written tasks of the open-ended type. Five models of the greenhouse effect appear among the answers, all more or less incomplete, but nevertheless with potential for development. The students' responses also indicate that they do not fully understand what fundamental societal changes would occur as a result of a drastic reduction in CO2 emission. On the other hand, they are rather well informed about how injurious depletion of the ozone layer is to humans. The findings are discussed, including implications for teaching.
