Adopting appropriate teaching methods and designing suitable teaching materials are among the major concerns of language teachers around the world. Although many teachers are eager to find the ‘best’ or most effective ways of teaching, there are no easy answers, given the wide range of sociopolitical contexts in which teaching takes place. In this interview, Alan Waters, a leading expert in English language teaching (ELT) from Lancaster University, talks about the trends and issues surrounding language teaching methodology, materials design, as well as teacher education in ELT. With extensive experience in the field, Alan has taught English as a foreign language and taken part in teacher training projects in various parts of the world, and has published several books and numerous journal articles. He is interested in all the main aspects of the theory and practice of ELT.
