We tell our students that learning is a hands on activity. They can't learn anything unless there is active participation on their part.
I can't learn to swim by watching someone splash around in a pool but truthfully, I am probably to old to learn anyway, so it doesn't matter. The Smart Board on the other hand, I am not too old to learn how to use. I know with proper training and practice, I could become an expert in no time.
