It's interesting how overly animated he is given that the student is not a child, but you can tell that she is pulled in by all of that energy. But if you look at other videos you'll see that most teachers are a little more contained (and maybe sane-seeming): https://www.youtube.com/watch?v=Swc0RTrxjpw

The one thing, I saw that in their teacher training they aim for a 70/30 ratio of student to teacher speech and I haven't found any videos where that was the case. Though maybe it is only for more advanced students.

Overall a really nice platform though!
