Ok, so I like this link because it emphasizes one often ignored point about "powerpoint" and similar softwares ... they're PRESENTATION tools, not online tools per se. I am rather surprised to find that many faculty are still loading publisher or home-grown Face-2-Face slide presentations into online courses and calling it engaging content... no, clipart is NOT engaging!
This ZaidLearn article is a good primer for anyone preparing a F2F presentation that is not intended for Web distribution... opinion alert! Seems we should respect these as two different mediums!
