Determination of pre-service elementary science teachers' knowledge level about global warming

The main purpose of this research is to determine of pre-service elementary science teachers? knowledge level about global warming.Survey method was used in this research, which is one of the quantitative research methods. Population of this research consist of undergraduate students, who have been studying in Gazi University Department of Elementary School Teaching, Science Teaching Program in 2008-2009 academic years. During research, data was gathered via closed-form Likert type Questionnaire, which was developed by the researcher. In this research two samples have been built up via cluster sampling method, which is one of the probability sampling methods. Questionnaire?s validity and reliability studies were carried out with the first sample, which consist of 328 pre-service science teachers. Then the application of the questionnaire was carried out with the second sample, which consists of 271 pre-service science teachers.According to the results pre-service science teachers? knowledge level about global warming is above average but they have lack of knowledge about some issues. It is thought that global warming issue in primary and undergraduate science programs should has been referred more adequately and should has been given an effective environmental education to pre-service science teachers. The knowledge levels of pre-service teachers, who have been studying in different disciplinary, could be compare with a similar study, which is been dealt with different disciplinary.
