Dear Nebu Sir,
Thank you for sharing your views on he Flipped Classroom approach.
One thing i would like to add is that a Flipped classroom gives room for participative collaboration making the paradigm shift from the sage on stage to everyone is a part of centrestage to learning.
It may not only be pre recorded videos but can be live conferences through skype and interactive online discussions or making collaborative powerpoints like using the google docs. it certainly has a backward approach to learning instead of classroom to learner , it is learner bringing learning to classroom.
