This book received the XV Research Award of the Spanish Association of Applied Linguistics (XV Premio de Investigacion de la Asociacion Espanola de Lingueistica Aplicada) 2012. The present volume bears witness to the Europewide character of the Content and Language Integrated Learning (CLIL) enterprise by featuring contributions from researchers and teacher-educators from a range of European countries spanning the geographical expanse of the continent from east (Estonia) to west (United Kingdom) and from north (Finland) to south (Spain, Italy). More importantly, the different national contexts are characterised by diverse cultural stances and policies vis-a-vis second and foreign language learning in general and learning specific languages in particular and it is evident that such contextual factors impinge on what are identified as central concerns both in CLIL implementation and research.
