The PBS video on Clintondale in the post below is excellent especially since it addresses what to do with students who are more disadvantaged. Both George and I have to deal with that in our schools. One of the things I do is have more fluid due dates. In fact my flipped students only have late assignments after the test is over. I also have lots of kids come to my class during our "flex" periods, as well as at lunch and after school. If you want to see Clintondale's videos go here. You can look a few posts below to see how to make your own videos. If you want more I have a book coming out in the late spring with Corwin that spends some time on flipping the classroom - and a lot more, but more on that in coming months.
