On the influence of environmental factors on moter development of young children(3) ―with especial reference to kindergarten and home―

The purpose of this study was to clarify the influence of environmental factors on the motor development of children. The running, jumping, throwing and ten events of motor skill of the 275 children of three (134 boys and 141 girls) were tested over three years. On the strength of the data, all the children were divided into two groups : the one was an improved group and the other was a stagnant group. Two main divisions were made according to the degree of their motor development is running, jumping, throwing and ten events. The factors which caused this division were made clear by the help of the discriminatory analysis attempted by T. Hayashi. Five biological factors such as height and age, and fourteen environmental factors, such as, home-play, width of ground, number of plaything and teacher\u27s leadership were used as independent variables. Though it was an established theory that basic motor ability, such as running and jumping, has high correlation to biological factors, the result of this analysis indicated the influence of environmental factors on their motor skill in kindergarten, especially the influence of playthings on the jumping and motor skill of children. The adequate equipment of playthings with kindergarten depends upon the teachers enthusiasm to encourage children to take exercises. From these results it can be estimated that environmetal factors play a vital part in the motor development of children in kindergarten
