In the attempt to evaluate the quality of teacher talk, recent communicative approaches have suggested that the modification of teacher classroom speech and the functional distribution of teacher talk in terms of pedagogical goals should be considered (Seedhouse: 1996). This study investigates the relationship between language use and pedagogic purpose from an analysis of a lesson transcript of a grammar lesson, and evaluates the quality of the teacher talk based on the Self-Evaluation of Teacher Talk (SETT) Grid. The purpose is to examine whether the teacher talk is appropriate in the classroom context or mode and to bring about a more conscious and effective use of teacher talk in her teaching profession in the future.
