Environmental education is a new field of education that emerges as a result of the perception that environmental degradation caused by human efforts to dominate nature can be compensated by itself. Environmental education is the main way of creating the necessary cognitive, affective and behavioral changes in the person. One of the most important tasks of every community for sustainable living is to equip children with attitudes, values, knowledge and skills necessary to protect their environment. Environmental education in preschool period has become widespread in recent years, even though it has great importance in terms of individual and social care. In parallel with environmental problems in Turkey, environmental education continues to grow and develop in all age groups. It seems that the programs prepared for the 5- 6 year old group in which preschool education is continuing in these age groups are still not enough. As seen in the literature, environmental education is efficient in natural environments in preschool period and when given by qualified, conscious teachers. In environmental education, the environment, the educational program and the role of the teacher are very important. Previous research suggests that the preschool education program and preschool teachers are not good at environmental education. The aim of this study is to get in-depth knowledge regarding knowledge of views of prospective preschool teachers’ about environmental education in preschool period, to identify the inadequacies of environmental education in the preschool period and to raise awareness of preschool teachers about environmental education.The sample of the research composed of 14 preschool teachers who accept to participate in the research from all kindergartens in Babaeski district of Kırklareli province.
