“The flipped classroom model encompasses any use of using Internet technology to leverage the learning in your classroom, so you can spend more time interacting with students instead of lecturing. This is most commonly being done using teacher created videos (aka vodcasting) that students view outside of class time.
It is called the flipped class because the whole classroom/homework paradigm is “flipped”. What used to be classwork (the “lecture”) is done at home via teacher-created videos and what used to be homework (assigned problems) is now done in class.”
