Task-based language learning involves presenting students with meaningful tasks to complete rather than focusing on language structures. A task requires students to use language to arrive at an outcome and engages cognitive processing. Effective tasks mirror real-world activities like talking to a doctor. This approach motivates students and gives them confidence to use the language. It also exposes them to a variety of natural language through collaboration. Teachers take on roles like preparing students and raising consciousness of language used. Students work in groups and provide feedback to one another, taking risks and innovating with language. While it can encourage ambitious language use, some students may rely too heavily on others and large classes present implementation challenges.
