"With the opportunity of online learning coming on,…what we talk about is shifting from this factory model system to a student-centered one that personalizes for each and every child," says Michael Horn, co-founder of the Clayton Christensen Institute and co-author of the new book Blended: Using Disruptive Innovation to Improve Schools. Horn recently sat down with Reason magazine Managing Editor Katherine Mangu-Ward during the National Summit on Education Reform in Washington, D.C., for a discussion of how blended learning joins traditional classroom models with software-based and online learning.
