"In this book we offer the informed and reflective practioner as the ideal agent for mediating between the practice and theory of language teaching. Some of the contributors might be labelled teachers, some materials developers, some applied linguists, some teacher trainers and some publishers, but all of them share four things in common: they have all had expereince as teachers of a second or foreign language, they have all contributed to the development of second language materials, they have are all well informed about developments in linguistic and psycholinguistic theory and they all have respect for the teacher as the person with the power to decide what actually happens in the classroom." --From the Introduction
