I honestly think a flipped classroom would work beautifully for my autodidact children to learn math concepts and other quantitative, applied work. I DO NOT think it should be used for nonquant subjects, and I see how it would be a disaster for students with different learning styles. Also, I feel bad for teachers. Many probably do not want to do this and many are likely not suited to it.

I personally would probably like it if I could speed up the lecture speed. I don't like lectures, because people talk too slowly. I have trouble watching TED talks. I would rather read a transcription.
