Hi Kris:
For me, a good back up plan can serve multiple purposes. One is for when we're having one of those days when everything planned can;t happen for whatever reason. These should be low tech, easy to implemment on short notice, and relative to the course topic.
Another is to have more varied activities than time will allow. The benefit is mixing up exercises to keep the class upbeat and lively by using diiferent learning strategies.
Regards, Barry
