Abstract
This research focused on clay modeling classes at Steiner schools and examined their significance for human development. It confirmed the founder R.Steiner’s viewpoints of human nature and children’s development, and discussed the literature about clay modeling and activities at the Nuremberg Steiner school, where the author conducted an observation of teaching practices. As a result, this paper clarified that clay modeling mainly works on the “Body (Leib)” due to the characteristics of the clay that is manipulated directly with the hands, on the “Soul(Seele)” due to the imaginative activities connected with learning content from classes spanning 1st to 8th grade work, and on the “Spirit(Geist)” by making invisible and abstract works in classes after 9th grade, so that the whole human being is educated systematically over 12 years of education. According to the above, this research may suggest how the subject teaching with art activities should be done in the Japanese education and the possibility of education for harmonious human development.
