Bonk, a professor of instructional systems technology at Indiana University, surveys this landscape in The World Is Open: How Web Technology is Revolutionizing Education (Jossey-Bass).
U. of Southern California's online master's in teaching, designed to "scale up" the production of instructors, enrolls 450 students in first 6 months -- more than four times the number in its on-campus program.
