Blended learning combines online and face-to-face learning in a planned, pedagogically valuable way where a substantial portion of content is delivered online and students typically meet face-to-face as well. It converges asynchronous online learning with synchronous human interaction in face-to-face settings, blending the effectiveness of the classroom with self-directed online learning. Blended learning can be defined as a combination of time spent learning in a supervised physical location and learning online, with the student having some control over the time, place, path or pace of learning.
