Task-based language teaching (TBLT) focuses on using authentic tasks to promote meaningful language use. It views tasks as the core unit for planning instruction and is presented as a logical development of communicative language teaching. Some key assumptions of TBLT include focusing on process over product, using purposeful and communicative activities, and sequencing tasks by difficulty level. A task in TBLT is an activity or goal carried out using language. The approach emphasizes learning language through interaction to complete tasks that could be needed in real life or have pedagogical purposes.
