Abstract
This study comparatively examined the environmental affordance of elementary children's rooms between the lower and the higher grades, and investigated the affects of the rooms'affordance on children's satisfaction of the rooms. Survey questionnaires were given to 412 elementary school children(221 in the lower grades and 191 in the higher grades), including their parents. Frequency analysis, $x^{k}$ -tests, t-tests, correlation tests, and regression analysis were mainly employed for the data analysis. The findings indicated that the environmental affordance of the children's rooms differed in each group in terms of the four dimensions: Social interaction, privacy, safety, and uniqueness. Meanwhile, the more environmental affordance was sufficient, the higher degree of the satisfaction was showed. In the lower grades, conveniency, accessibility, social interaction, and uniqueness were influenced their satisfaction of the rooms, whereas social interaction, conveniency, order, and privacy were affected the children's satisfaction in the higher grades.
