Power in the Classroom [PDF ebook] 
Communication, Control, and Concern

In the belief that power is something that is negotiated by participants in the instructional process and with the goal of understanding how communication and power interact, this book looks at power and instruction in many different ways. Drawing from the lessons of the social sciences generally, it examines research that has been conducted by instructional communication specialists, looks at newer approaches to power, presents a status report on what is now known, and points to the divergent directions that offer opportunities for future scholarship.
