Outdoor day care was provided individually to preschool children with symptoms of development disorders. Most of the children showed a kind of clumsiness but the stimulation of outdoor day care effected improvement. This developmental progress helped them to create, determine, and execute activities on their own. Accordingly, their initiative and motivation toward these activities were also improved. The results demonstrated the importance of children's firsthand learning experiences by trial and error at their own paces. Furthermore, it is important to have nursery staff who have the capacity to wait and watch carefully how children will experience these outdoor activities. Finally, it is suggested that the outdoor day care method is very effective to stimulate preschool children's development.
