Teachers always have been and always will be the essential element in the classroom. They can create magic inside four walls, but they have never been able to create learning environments outside the classroom like they can today, thanks to blended learning. Blended learning allows students and teachers to break free of the isolation of the classroom. Blended learning can have different definitions. First and foremost, blended learning is all about personalizing learning for students. It's not necessarily a fundamental redesign of the classroom, but it is a fundamental redesign of the time outside the classroom. The important difference in these definitions is the element of student control that allows the student to determine where he or she can learn and, equally as important, at the speed that allows content mastery.
