Webster's points are: (1) the principal must teach teachers using an informed vision of the school as an ideal setting for learner growth, (2) teaching the universe of discourse and its skills are the most important activities in schools because discourse is the master switchboard of all teaching and learning, and (3) effective principalship is eclectic and pragmatic. The focus of the book includes educationally sound, legally defensible teacher evaluation that has been developed with other principals who have perfected the science of writing up teachers. Innovations in Webster's method involve approaches to staff development, different portrayals of the authoritative basis of the principalship, and the evaluation of teaching from the point of view of discourse among practiced and inexperienced teachers.
