What is blended learning?

Blended Learning means combining online and offline educational methods so that they reinforce each other. Blended Learning requires that the online and offline methods are carefully selected and designed, and not meant to replace one or the other. A proper ‘constructive alignment’ between the learning activities and goals is essential for deep learning. Take for example instructional videos: they will be ineffective if provided as additional material without changing lecture content and introducing interaction. However, they can be very effective when they are essential to successfully participate in class discussions, quizzes or assignments.
