The aim of the research is to examine the environmental awareness and attitudes towards the environment of 5–6-year-old children attending nature-centred private kindergartens and public kindergartens. The study group of the descriptive research that used a screening model consists of 48 children from nature-centred Private Maki Kindergartens and 48 children from public kindergartens in the province of Balikesir in the 2020–2021 academic year. A Personal Information Form and Environmental Awareness and Attitude Scale for Preschool Children, developed by Soydan and Samur (International Electronic Journal of Environmental Education, 7(1), 78–97, 2017) for 60–72 months old children, were used in the study. The scale consists of two sub-dimensions as Attitude Towards Environment (15 items) and Environmental Awareness (11 Items) and 26 pictures. The Cronbach α coefficients of the Environmental Awareness (.74) and Attitude (.78) Scale for Preschool Children and the overall scale (.82) were calculated. The data were collected by the researcher through one-on-one meetings with each child. The mean, mode, median, skewness and kurtosis values of the variables in the study were calculated. To determine whether the environmental awareness and environmental attitudes of the study group differ according to the school they attend, independent samples t-test was conducted. According to the results of the research, a significant difference was found in environmental attitudes and environmental awareness of children in nature-centred kindergartens compared to children in public kindergartens. Children attending public schools are less exposed to the environment. Preparing the Pre-School Education Program in an environment-friendly manner to increase the environmental awareness of children attending public schools will be effective in terms of making a difference in their attitudes towards the environment.
