Content-based instruction is a method that integrates language and content learning. It focuses on using meaningful content from other subject areas as the basis for developing language skills. Key aspects of CBI include using the content and students' background knowledge and experiences to drive the curriculum; focusing on purposeful, contextualized language use; and having students play an active role in interpreting information while teachers facilitate learning. CBI aims to make language learning more motivating by focusing on meaningful ideas rather than just language forms.
