Makila,
Goo - especially the moving back and forth between PPT and... whatever: discussion, illustrations, case study, written activity or exercise, demonstration. I think PPT slides work best for me when I can create my own, then have each slide more of a shorter, bullet-style outline of main points that allow me to elaborate or ampflify. I feel that's what I'm there for - to expand on the basic information (vs. putting it all into the PPT).
Regards, Barry
