Task-based language teaching (TBLT) is one of the widely discussed teaching approaches at present. Teaching a lesson using tasks needs careful consideration of the age and interests of the learners. This paper provides an overview, characteristics and advantages of TBLT; highlights teacher and student roles; and explores teachers' perceptions of task-based language teaching. For this, I purposively selected two English language teachers teaching at secondary levels as the participants of my study. This study applies ethnographic research method and explores the participants' perceptions of using language tasks in their classrooms. The findings suggest that though English language teachers hold positive attitudes on task-based language teaching as a current EFL approach, they are not well aware of the methods of using this approach in their classrooms.
