How can Berklee offer online courses at one-third the cost of residential classes?

Robert Ubell, the vice dean emeritus of online learning at New York University's Tandon School of Engineering, has written in EdSurge that students will increasingly seek online courses and that higher education is getting more comfortable with them. He says online learning can be adopted without excessive expense, and recommends that colleges consider hiring an online program manager and moving carefully, as well as expanding the student body to include other types of students the way Berklee did.
