I think this video shows a very interesting educational model and I'm so glad that it's been successful in their school! Most of the time when I think of progressive educational models, I assume that they could only work for older students (such as university students or at least older high school students), so when the speaker explained in the video that his school has younger students I was happily surprised.
My favourite thing about this video is that it reminds me of how Gaby teaches us body percussion in class. I love that you can see and hear them become more in sync with each other as the video goes on. Also: notice that he doesn't count them in!
