Technology in Composition’s History and Pedagogy

On the Blunt Edge: Technology in Composition’s History and Pedagogy tells the stories of composition’s techno-history, from the roads of the ancient world, which allowed students to travel to school, to the audio-visual aids that populate the classrooms of the modern world. Computers are only a small part of this discussion, a technological Johnny-come-lately in a long-running pedagogical palaver.
