What are the characteristics of true education?

One contemporary educationist has identified three characteristics that distinguish true education from such things as rote learning, purely mechanical training, indoctrination or brainwashing. True education,

(a) Deals with knowledge that is recognized worth-while and capable of achieving a voluntary and committed response from the learner;

(b) Leads to a quality of understanding that gives rise to new mental perspective in the learner.

(c) Uses methods that encourage the exercise of judgment by the learner and the use of his critical faculties.
