Kimberley,
That's great! I always have new instructors sit in other instructors classes. It gives insight to how different instructors approach similar topics, or demonstrates the variety of creative methods different instructors have come up with. I'm sure most observers learn to take what they feel as meaningful and adapt those methods and activities into their own version. Also, even undesirable instructor traits can be useful to witness, as these can drive home the point not to follow that path.
