This interesting article, "Three things I learned through teaching a flipped class," is a report from the classroom by a teacher who is using the "flipped classroom" model pioneered in Khan Academy partnerships with schools. It's good to get these first-hand impressions from a working teacher.

"I’ve always felt that, within 5–10 years, we won’t be talking about the 'flipped classroom' — we’ll just be talking about the 'classroom.' This way of teaching, in other words, will be normative and it will be straight lecturing that will seem odd, out of place, and ineffective. Maybe we’re closer to that point than I first thought."
