Justified or not, lecture stands as perhaps the single symbol of non-progressive learning.
The visual is clear enough for most. A sage-on-stage stands and delivers wisdom and expertise while attentive learners jot down what they can that sounds important for later exploration.
In the case of an incredibly curious and resourceful, this model can function, and has for decades, if not centuries. But even a functioning lecture model pales in comparison to a well-designed learner-environment where learners ask question, self-direct, revisit old thinking, and self-initiate the transfer of important thinking.
In this Edutopia video as part of their Big Thinkers series, Sal Khan of the Khan Academy discusses mastery learning, personalized learning, access to content, simulations, and the need to “get the lecture out of the room.” The big idea of the video was to promote the Khan Academy’s exercise platform.
Little of it is new beyond the titular quote which really resonated–itself an argument itself for the flipped (and blended learning) model the Khan content supports so well.
Above all else, blended learning is about rethinking interaction patterns, including how we use tow of our most valuable resources: time and space.
