While a great deal has been written on the theory and practice of communicative language teaching, there have been comparatively few studies of actual communicative language practices. A classroom-based study of communicative language practice revealed the persistence of non-communicative patterns of interaction. A follow-up study demonstrated that it is possible for teachers to foster more communicative language use. These studies demonstrate the importance of validating theory against what actually happens in the classroom.
