This study was conducted in order to examine the effect of environmental education program supported by multimedia on the environmental attitudes and awareness of children. The effect of the Environmental Education Program on the attitudes and awareness towards the environment of the children attending kindergarten was examined by the Pre-test Post-test Control Group experimental design. The nursery classes of two primary schools in Sivas center giving education before noon were determined as the study. The "General Information Form" developed by the researchers and the "Environmental Awareness and Attitude Scale for Preschool Children" developed by Soydan and Samur (2013) were used as data collection tools in the research. "Environmental Education Program Supported by Multimedia" developed by the researchers was implemented in order to reveal the effect of the Environmental Education on the attitudes and awareness of the children attending the kindergarten to the environment. The effects of the environmental education program supported by multimedia on the children's environmental attitudes and awareness were examined by the Mann Whitney U Test to make comparison among independent groups, and the Wilcoxon Signed Rank Test was used for comparison among dependent groups. In order to determine the permanence of the education, the Environmental Awareness and Attitude Scale for Preschool Children was reapplied to the children in the experimental group four weeks after the training program was completed. As a result, it was determined that the Environmental Education Program supported by Multimedia is effective on the attitudes and awareness of the children towards the environment and this effect is permanent.
