- Task-based language teaching (TBLT) uses tasks as the core unit of planning and instruction in language teaching. It was presented as a logical development of Communicative Language Teaching. - In TBLT, the focus is on the process rather than the product. Learners learn language by interacting communicatively and purposefully while engaged in meaningful activities and tasks. - Willis proposed that tasks be sequenced according to difficulty, and recommended a task cycle including pre-task, task, planning, report, language focus, analysis, and practice stages.
