Blended learning is defined as a formal education program in which a student learns:
(1) at least in part through online learning, with some element of student control over time, place, path, and/or pace;
(2) at least in part in a supervised brick-and-mortar location away from home;
(3) and the modalities along each student’s learning path within a course or subject are connected to provide an integrated learning experience.
There are a few different models of blended learning. To learn more about these models, read here: Blended Learning Models Simplified
