Scientific and technical French

" Make your pupil attentive to the phenomena of nature, and soon you'll have him curious; but, to feed his curiosity, never hurry to satisfy it. Put the questions within his reach, and let him solve them. Let him know nothing because you have told him, but because he has understood it himself; let him not learn science, let him invent it. If you ever substitute authority for reason in his mind, he will no longer reason; he will only be the plaything of other people's opinions. "The idea of usefulness. Children must be made aware of the usefulness of what they learn. In this way, he will be accustomed to not allowing himself to be led blindly, and his initiative will increase." Emile ou de l'éducation. Jean Jacques ROUSSEAU.
