Understanding.

Discipline is born when the child concentrates his attention on some object that attracts him and which provides him not only with a useful exercise but with a control of error. Thanks to these exercises the child becomes calm, radiantly happy, busy, forgetful of himself and, in consequence, indifferent to prizes or material rewards.

Maria Montessori

Children have real understanding only of that which they invent themselves, and each time that we try to teach them something too quickly, we keep them from reinventing it themselves.

Jean Piaget

Children learn how to make good decisions by making decisions, not by following directions.
