Content and language integrated learning (CLIL)[1] is a method of teaching school subjects in a foreign language, thus teaching both the subject and the language. It has many synonyms such as bilingual education, content based instruction, English (or other languages) as medium of instruction.[2]
Content-based instruction (CBI) is a similar approach. The term CLIL is more common in Europe, although the terms are sometimes used interchangeably.
CLIL has been identified as a priority by the European Commission [3] because
It can provide effective opportunities for pupils to use their new language skills now, rather than learn them now for use later. It opens doors on languages for a broader range of learners, nurturing self-confidence in young learners and those who have not responded well to formal language instruction in general education. It provides exposure to the language without requiring extra time in the curriculum, which can be of particular interest in vocational settings.
