Since there is no single set of abilities running throughout human nature, there is no single curriculum which all should undergo. Rather, the schools should teach everything that anyone is interested in learning.
John DeweyExperiences in order to be educative must lead out into an expanding world of subject matter, a subject matter of facts or information and of ideas. This condition is satisfied only as the educator views teaching and learning as a continuous process of reconstruction of experience.
John DeweyFailure is instructive. The person who really thinks learns quite as much from his failures as from his successes. Genuine ignorance is profitable because it is likely to be accompanied by humility, curiosity, and open-mindedness; whereas ability to repeat catch-phrases, can't terms, familiar propositions, gives the conceit of learning and coats the mind with varnish waterproof to new ideas.
