My experience of the flipped classroom is that students are to view videos or read material or do whatever other passive thing introduces them to the topic at hand and then during actual class time they solve problems and the teacher is there to assist.
I was skeptical, but my son's AP Economics teacher did a flipped classroom in the way I have described and it was incredibly effective.
My son did honors precalculus two years early. His teacher also did not teach, but he also didn't do a flipped classroom. If he had, it would have been much more effective.
