Apparently this gentleman is the founder of a school of education known as the silent approach. The gist of this school is that the teacher cannot teach but can only hope to awaken the learner’s desire to learn. Gattegno is a wise man, especially where language instruction is concerned. I will try to learn more from him.
Power to the learners! Overthrow the teachers! Overthrow the educational establishment. The most inexcusable is the university. Anything taught at a university should be available to everyone in a free market place of knowledge, ideas and thnking. And whatever is of no interest should be abolished (and that would be a good portion of tenured professors and what they try to teach.)
