Learning through another language is a multilingual (Catalan, Spanish and English) compendium of valuable contributions from leading investigators to further the understanding and practice of Content and Language Integrated Learning (CLIL). The book offers an ample range of perspectives regarding CLIL learning and teaching. This review takes a look at how the collection deals with the following topics: the challenges involved in plurilinguistic education (chapters 1-4); the integration of content and language in the discourse of CLIL classrooms (chapters 5-7); and the need for in-service and pre-service teacher education and the role of collaboration among subject and linguistic specialists on the one hand, and investigators and practitioners on the other, in the successful implementation of CLIL programmes in the educational system (chapters 8-10).
