This document provides information about task-based language teaching (TBLT). It begins by defining a task as "an activity where the target language is used by the learner for a communicative purpose (goal) in order to achieve an outcome." It then explains that TBLT engages learners in authentic language use through a series of tasks to both acquire new linguistic knowledge and proceduralize existing knowledge. The document outlines the rationale and design of TBLT, including its focus on meaning over form, motivation through task achievement, and negotiation of learning difficulty. It also discusses the role of the teacher in guiding tasks and providing feedback, as well as the role of students in interacting and presenting results.
