The purpose of this study is to determine the views of social studies of teacher candidates about light pollution. This research is designed by using qualitative research method. In the research, case studies--that is one of the qualitative research methods--is used. Case study is a kind of research that offers a rich perspective on analyzing the learning and management implications of what educators and students have gained through experiences they have gained. Maximum diversity sampling--one of the purposive sampling methods--was used. A total of 40 students from 1st, 2nd, 3rd, and 4th grades were included in the Social Studies Teaching Department of Agri Ibrahim Çeçen University Faculty of Education. A semi-structured interview form consisting of 6 open-ended questions developed by researchers was used to collect the data. After the questions that take place in the interview form were prepared, expert opinion was consulted. After the expert opinion was received, the questions were revised and piloted on 20 teacher candidates. Pilot application form was prepared and presented again to expert opinion. After receiving the feedback from the experts, the final form was given to the interview form and applied in the spring semester of 2016-2017 academic year. In the analysis of the data, a descriptive analysis method was used. As a result of the study, it was determined that social science teacher candidates generally have information about light pollution but having this information is not enough for some of them. Social Studies Teacher candidates have shown that pollution damages living and non-living assets in general and that light pollution is among pollution types. Excessive use of light among the causes of light pollution, lights overflowing from houses and buildings, and prospective teachers showing the absence of correct light use, have indicated that light pollution causes significant negative effects on both humans and the living and nonliving environment. Teacher candidates have expressed the opinion that people need to be conscious in order to reduce the effects of light pollution. It is remarkable that some teacher candidates should not have knowledge in this regard.
