Abstract
In Japanese nursery school, there is no standard of group formation of one-year-old children's class which can be seen in many foreign countries. In the existing circumstances, many classes respectively have large group formation, that is, each class consists of children whose range of growth is wide. In this study, in relation to the group formation of classes which is most important when a nursery room is planned, they is divided into the three conditions, that is, the group formation of the minimum age of 1 year and 6 months - the maximum age of 2 years and 7 months, that of the min. 1 year and 2 months - the max. 2 years, and that of the min. 1 year and 1 month-the max. 2 years and 7 months, and in each condition the experimental care is taken. After this, the influence on the one-year-old children and the nurse staffs is investigated and the suitable group formation is considered. As the result, this point is confirmed. In group formation of one-year-old children, conversions of nursery activities and nurse staffs' fatigue are relatively lightened in the nursery room planned so that each class may consist of children whose range of growth is narrow.
