This document describes Caleb Gattegno's method of language teaching which is based on the premises that the teacher should remain silent and encourage learners to produce as much language as possible. It involves learning through discovery and problem-solving using physical objects, rather than repetition. The method focuses on propositional meaning of sentences rather than communication, uses vocabulary as a central dimension of learning, and relies on an "artificial approach" with the teacher remaining silent and learners using inner criteria.
