Growth concepts as they relate to motor development in children are discussed. The focus of this monograph is on structuring situations to help children develop physical skills. The first chapter deals with individual growth patterns, genetic and environmental influences on human growth, and the development of physical efficiency. Chapter two examines the changes of appearance that accompany growth. In the third chapter, increasing ability and achievement potential are examined as a part of the natural maturation process. The psycho-social aspects implicit in human growth are discussed in the fourth chapter. The final chapter considers the influence of the maturation and development rate upon setting and realizing personal goals. (JD)
