Done right, blended learning breaks through the barriers of the use of time, place, path to understanding, and pace to allow each student to work according to his or her particular needs—whether that be in a group or alone, on practice problems or projects, online or offline. It preserves the benefits of the old and provides new benefits—personalization, access and equity, and cost control.
The question is how educators can capture these benefits. Blended learning is not inherently good or bad. It is a pathway to student-centered learning at scale to allow each child to achieve his or her fullest potential, but it is not a guaranteed success.
