Abstract: Task-based language teaching (TBLT) focuses on the use of authentic language and meaningful tasks. There are varieties of tasks in English teaching, with each of them designed to solve a communicative problem. The task should have some connections with a real world of learners’ lives and learning experience and stimulate their interest and participation. Assessment is based on task outcome rather than on accuracy of language forms. This paper aims to elaborate the theoretical basis and features of TBLT, its application in senior middle English classes, and its advantages and disadvantages.
