CLIL

Content and Language Integrated Learning (CLIL) is a dual-focused educational approach in which an additional language is used for both the learning and teaching of content and language. The term was coined by David Marsh in 1994 and gained traction primarily in European education policy, becoming a cornerstone of the European Commission's multilingualism strategy.

Coyle's 4Cs Framework

Do Coyle (1999; elaborated in Coyle, Hood & Marsh, 2010) proposed the 4Cs as a planning and analysis framework for CLIL:

• Content -- Progression in subject knowledge and skills tied to a defined curriculum.
• Communication -- Using language to learn while learning to use language; both subject-specific and general academic registers.
• Cognition -- Engaging higher-order thinking skills (analysis, evaluation, creation) alongside lower-order ones, linked to Bloom's taxonomy.
• Culture -- Developing intercultural awareness, understanding otherness, and building plurilingual identity.

The 4Cs are interdependent: effective CLIL integrates all four simultaneously rather than treating them sequentially.

CLIL vs. Immersion

CLIL is not simply immersion by another name. In immersion (e.g., Canadian French immersion), language learning is incidental to content. In CLIL, both language and content have explicit learning objectives. CLIL teachers are expected to attend systematically to the language demands of their subject, scaffolding academic literacy rather than assuming it will develop through exposure alone.

Practical Implications

CLIL demands significant teacher competence in both subject and language, which creates training challenges. Critics note that without careful language scaffolding, CLIL risks becoming "content teaching in L2" with limited language development -- the so-called "language thinning" problem.
