What happens between student and teacher when computers move into the classroom? Drawing from over 20,000 episodes in the longitudinal database of Apple Classrooms of Tomorrow, this book gives case studies and teacher testimonies, addressing teachers' perennial concerns: teacher learning and teacher beliefs about instructional change; redefining student and teacher roles; maintaining student engagement; reducing teacher isolation; managing the technology-rich classroom; and support for instructional change from school principals, school districts, technology trainers and colleagues.
