CLIL (Content and Language Integrated Learning) involves teaching content subjects like science or social studies in a foreign language. It aims to create connections between students' lives and what they learn in school. Students learn language through content and content through language use. CLIL recreates the natural conditions of first language acquisition. It provides rich input, intake, and output opportunities to support language learning, though not all input is intake. CLIL fits within national curricula and seeks to enrich learning environments through cooperation between language and content teachers using common strategies and activities. Thinking and cognition drive CLIL methodology, which focuses on developing students holistically through meaningful personal and social reflection.
