In undeveloped social groups, we find very little formal teaching and training. Savage groups mainly rely for instilling needed dispositions into the young upon the same sort of association which keeps adults loyal to their group. They have no special devices, material, or institutions for teaching save in connection with initiation ceremonies by which the youth are inducted into full social membership. For the most part, they depend upon children learning the customs of the adults, acquiring their emotional set and stock of ideas, by sharing in what the elders are doing.

[T]he schools, through reliance upon the spur of competition and the bestowing of special honors and prizes, only build up and strengthen the disposition that makes an individual when he leaves school employ his special talents and superior skill to outwit his fellow without respect for the welfare of others

The aim of education is to enable individuals to continue their education — or that the object and reward of learning is continued capacity for growth.

The importance of language in gaining knowledge is doubtless the chief cause of the common notion that knowledge may be passed directly from one to another. It almost seems as if all we have to do to convey an idea into the mind of another is to convey a sound into his ear. Thus imparting knowledge gets assimilated to a purely physical process.

The teacher loses the position of external boss or dictator but takes on that of leader of group activities

The development occurs through reciprocal give-and-take, the teacher taking but not being afraid also to give.

In the olden times, the diversity of groups was largely a geographical matter. There were many societies, but each, within its own territory, was comparatively homogeneous. But with the development of commerce, transportation, intercommunication, and emigration, countries like the United States are composed of a combination of different groups with different traditional customs. It is this situation which has, perhaps more than any other one cause, forced the demand for an educational institution which shall provide something like a homogeneous and balanced environment for the young.
