This revision of a previous edition discusses an approach to language teaching called the Silent Way. This method is based on the notion that learning a foreign language is in many respects radically different from learning the mother tongue. It can be learned in the schools by artificial methods and with materials designed for the purpose. The techniques in the Silent Way make it possible for the teacher to say less and the students to say more as the lessons advance. The specific subjects covered in this book are: (1) the subordination of teaching to learning in the case of foreign languages; (2) the spirit of a language -- its structure, and the literature and philosophy of the group using it; (3) the distinction between language and vocabulary and the idea that much language use can go on with a small functional vocabulary; (4) a discussion of materials for vocabulary development; and (5) a discussion of results one might expect and an exposition of the rationale for this method. An appendix contains ten testimonials to the method by teachers who used it in teaching several languages. (AMH)
