A determination was made of whether any change occurred in the self-concept of children in the open space environment as compared to the change of self-concept of children in a self-contained environment. A total of 216 children, part from an open space environment school and the others from self-contained classrooms at grade levels with one teacher per grade level, were administered the Self-Social Symbols Tasks and the Children's Self-Social Constructs Tests. From the data collected, it was concluded that: 1) children in open space have greater identification with the group than the children in self-contained classrooms; 2) children in open space have an increase in self-esteem while children in self-contained classrooms demonstrated a loss; 3) children in open space do not view themselves differently in the relationship of their size to that of an adult; and 4) children in open space do not identify with any one particular teacher.
