Book excerpt: This Critical Perspectives on Language Teaching Materials brings together a collection of critical voices on the subject of language teaching materials for use in English, French, Spanish, German and Content and Language Integrated Learning (CLIL) classrooms. It is firmly located within the 'critical turn' in Applied Linguistics and seeks to build on the growing body of work in this vein. Collectively the authors take it as axiomatic that the politics of representation and identity, and issues of ideology and commercialism cannot be neglected in any serious study of language teaching materials. Rather, it sees these issues as central. The book draws on research carried out in the UK, Spain, North America and Brazil, and is aimed at language teachers, teacher educators, students, researchers, materials writers and those working in the materials publishing industry.
