I ran across an old paper today written by Julian Weissglass in 1976 and it seemed somewhat relevant to our group. It included the following list:
Most of the suggestions are fairly straightforward and entail general courtesy. I’m sure most are already aware of and use these suggestions regularly, but as many in the group are teachers/professors who may be experimenting with flipped classrooms, you may find some of the commentary in this MAA paper from the 1970’s fairly useful, and may want to “borrow” portions for your own classes.
