A COMPARATIVE STUDY ON THE GROWTH IN HEIGHT AND WEIGHT OF NORMAL, BLIND, AND DEAF SCHOOL-CHILDREN.

摘要

One important conclusion to be drawn from the foregoing results put together is: Prior to the age of 5 or 6 the blind and deaf taken as a group are not notably different from the normal in the average level of growth or the standard deviation. Later, however, the average level of growth rises higher for the latter than for the former as they advance in age, the difference reaching the maximum at 18 or 19 (ages at which the process) of growth is brought nearly to a close, while the standard deviation becomes greater with age for some time former than for the latter, the ratio culminating at about 14 or 15 in males and about 12 in females and then declining till it converges to 1, i.e., it becomes equal for the former and the latter group, at 18 or 19. This seems an important fact to be noted in all special-school education, because a widely varied distribution of the period of growth in children makes uniform education very difficult in these schools. A class formed by age, for instance, will naturally be a promiscuous mixture of children for different in the level of growth. Such in convenience is to be met with to some extent in schools for normal children, but it is incomparably greater in special schools, according to the author's own educational experience with physically handicapped children. It is therefore desirous that some adequate measures be taken for these children from a more reasonable point of view.
