This book on the theory and practice of language teaching and learning develops the argument that learning a language depends on "what goes on inside and between the people in the classroom." The material is presented in three parts. Part 1 is a nontechnical account of how teacher and students interact, and of how the mind deals with foreign language data. The second part discusses a wide range of techniques for pronunciation, memorization, grammar, audiovisual and other aids, oral activity, writing material for one's class, and adapting existing texts. The emphasis is not primarily on amassing a large number of workable techniques, but on understanding the technique, seeing what is behind it, and how it is related to other techniques. The last section looks at basic linguistic data, especially phonology and grammar. The final chapter gives suggestions for further reading. (AMH)
