This presentation explores the varieties of Content and Language Integrated Learning (CLIL) programmes that go under this umbrella term and explains the original four Cs of CLIL: content, communication, culture and cognition. The advantages and disadvantages of implementing a CLIL approach in the curriculum will be compared and some of the learning strategies to develop the cognitive domain while teaching a foreign language will be explained. The changes required in terms of professional development for teachers and changing roles for students will be explored and the efficacy of introducing a CLIL approach for bilingualism in a globalised world will be promoted.
