CLIL (Content and Language Integrated Learning) is an approach where subjects like science, history, or geography are taught through a foreign language. It's not language teaching and it's not subject teaching — it's both simultaneously. CLIL has become the dominant approach in European bilingual education and is expanding globally.
CLIL lessons are built around four pillars: Content (subject matter — what students learn about), Communication (language used to learn and express — the language students need), Cognition (thinking skills — from lower-order recall to higher-order analysis), and Culture (cultural awareness and intercultural understanding). A strong CLIL lesson integrates all four.
Example: A CLIL science lesson on the water cycle. Content: evaporation, condensation, precipitation processes. Communication: present simple for processes ("Water evaporates"), sequencing language ("First... then... finally"). Cognition: predicting what happens if variables change. Culture: water scarcity in different regions.
CLIL lessons require dual planning: content objectives ("Students will understand the causes of World War I") AND language objectives ("Students will use past simple and past continuous to describe events," "Students will learn 15 key vocabulary items"). Both must be explicit and assessed.
Structure: Input phase (teacher presents content with language scaffolding) → Processing phase (students work with content using target language) → Output phase (students produce language demonstrating content understanding). Build in language support at every stage: word banks, sentence frames, graphic organizers.
CLIL students need three types of language support: vocabulary (key content terms pre-taught and displayed), functional language (how to classify, compare, hypothesize, evaluate), and discourse (how to structure an explanation, argument, or report). Create "language toolkits" for each lesson — reference sheets students can access while working.
The key question: do you assess content, language, or both? Best practice: assess content through the medium of the foreign language, but don't penalize language errors that don't obscure meaning. A student who writes "The plants is growing more faster with light" demonstrates content understanding despite grammatical errors.
Ideally B1+ for secondary subjects. However, primary CLIL can start from A1 with highly scaffolded, visual content. The key is matching content complexity to language level — a complex physics concept needs higher language proficiency than a simple art project.
CLIL works best with collaboration between subject and language teachers. If you're working alone, choose content areas you're comfortable with. Primary CLIL topics (weather, animals, the body) are accessible to most teachers. Secondary topics may require co-planning with subject specialists.
