This edited book compiles pedagogical practices and studies of Content and Language Integrated Learning (CLIL) from two sites: Spain, where CLIL has been widely implemented for more than a decade, and Japan, where the CLIL approach is still in its relative infancy, and quickly gaining momentum. Focusing on three aspects of the CLIL implementations: policy, practice and pedagogy, the authors describe how CLIL has evolved in distinctive socio-political, historical and cultural contexts.
