I find the idea of the Flipped Classroom very interesting and innovative, although I wonder how it would work in the early childhood prep to 3 classrooms.
I am also wondering how it would work in the lower socio-economic schools. I wonder if all students would have freely available computers and internet access, parents to help/guide the students with 1. technically eg. getting the program set up to watch the lecture and 2. support for processing the information learnt and finally the time to watch the lectures. Some students might be flooded with chores and need to help their parents around the home or business outside of school hours.
I do believe that if the Flipped Classroom were able to work, the depth of learning in any particular subject would greatly be intensified as time would be freed up to practice and master the concepts rather than being introduced to it.
