ABSTRACT
It is pointed out in the preceding chapter that the science of geography appears early in the curriculum of the elementary schools because the arrangement of experiences in a general pattern of space is a natural extension into the sphere of abstract thought of the space ideas which pupils cultivate through their contacts with the objects in their surroundings. Similarly, history is introduced into the curriculum of the elementary schools as a means of extending another system in which all experience is arranged, namely, the system of time. Time is as universal a form of experience as space. A child’s ability to locate events in time matures more slowly, however, than his ability to locate objects in space.
