Creative thinking is valuable and necessary in society today and in the development of solutions to environmental issues. Fostering creative thinking skills and environmental values should begin early in life. The purpose of this study was to investigate the influence that a nature preschool experience has on the development of creative thinking in young children. The "Thinking Creatively in Action and Movement" (TCAM) instrument was used to assess creative thinking through measuring children's fluency, originality, and imagination scores at four nature preschools and one non-nature preschool. Results indicate that nature preschooler's creative thinking scores increased significantly from pretest to posttest measures. Results further suggest variation in influence on creative thinking across the nature preschool sites.
