A highly respected overview of the field of instructional supervision that covers the three domains of supervision: instructional development, curriculum development, and staff development. The authors adhere to the beliefs that supervisors should look at teaching before looking at the teacher, and that the supervisor should look at the classroom and school environment within the context of instruction. Continuing in approach and philosophy as previous editions, the Eighth Edition will continue to lean toward practice, with heavy emphasis on the supervisor's responsibilities as an instructor.
