In order for environmental education to be revitalized and improved, efforts to improve the professionalism of environmental education instructors, which are the subjects of cooperative education, are also very important. The purpose of this study is to find out the ways in which instructors practicing early childhood environmental education provide detailed teaching and learning experiences in early childhood education institutions and to have opportunities to reflect on how to improve early childhood environmental education methods and lecturers. The results is followed: Instructors who work for early children in environmental education fields have troubles such as too many children in a class, uncertainty of belief on teaching contents, poor technical knowledge on early children, and insufficient cooperation with educational institutes etc. This study suggest that practical environmental education contents for early children and training programs for professional instructors be provided.
