"In this book we offer the informed and reflective practitioner as the ideal agent for mediating between the practice and theory of language teaching. Some of the contributos might be labelled teachers, some materials developers, some applied linguist, some teacher trainers and some publishers, but all of them have experience teaching a second or foreign language, have made a contribution to the development of second language materials, are well informed about developments in linguistic and psycholinguistic theory and respect the teacher as the person with the power to decide what actually happens in the classroom" Brian Tomlinson.
