I have heard a lot recently about flipping classes. I started on the ground level by keeping up with the two teachers who started the vodcasting. I tried to have my students create vodcasts at the time (about 3 years ago), but wasn't really successful. The idea continues to be interesting however. Many people refer to Kahn Academy http://www.khanacademy.org/#biology as a source of videos. I plan to try some "flipped" lessons this spring to see how it works. I can see that the concept seems to lend itself well to math. There are some difficult concepts that I teach that could work better for students if flipped. One of the most difficult subject matters for my biology students is DNA, or specifically transcription and translation. I think that will be my first experiment in flipping. I would also like to get my hands on one of those compact flash camcorders like the Kodak Playsport so that I can record my own lectures.
