Hi Carolyn: Your use of time sequencing is innovative and I think you are fortunate your curriculum allows that kind of adjustment. It sounds like a good idea, although not all teachers have lecture/lab, and would be unable to make such a switch. However, having course related material that doesn't take a lot of preparation and is very low tech (so it could be used anytime-anywhere) would very hehpful when a teacher is having "one of those days" when everything seems to be going awry.
