Exp loring  Classroom Discourse : Language in Action sets out to propose that the concepts of CIC and SETT frame- work ，which combine conversation analysis with teacher reflection through  classroom  interaction ，provide  an  approach  to  enhan- cing both teaching effectiveness and teachers' professional development． The book stands out  as substantially  important  literature in classroom discourse studies with its novel perspective ，rich material and linkage between linguistic theories with teaching prac- tice and teachers' professional development．
