Mindful of the fact that cultures are now more interdependent than ever, this book explores the development of critical cultural awareness through the processes of teaching and learning about foreign cultures. It draws upon theoretical foundations relating to inter- and intra-cultural communication from contemporary philosophical movements, namely Critical Theory and Postmodernism. The study adopts Critical Pedagogy, as it is described by Freire, Giroux and others, as the educational framework providing guidelines for taking a critical perspective towards both native and foreign cultures. It examines the critical dimension of some selected documents and models used worldwide for teaching/learning culture within foreign language classes. It includes a research project carried out among secondary school teachers of EFL in Portugal whose national syllabus suggests a critical approach to English-speaking cultures. This project aimed to illustrate how practising teachers approach foreign cultures critically, to provide some grounded theory for a definition of critical cultural awareness within foreign language/culture education, and to inspire a proposal for teacher education and development. Finally, this book submits a general proposal for the development of critical cultural awareness and intercultural communication competence among prospective and practising teachers of foreign languages/cultures.
