hello Sylvia:
Mostly, I have to listen and learn in these conversations, but I would like to offer up a piece of very wise advise I picked up at an EduCAUSE conference a couple of years ago.
A paraphrase (which, of course, runs the risk of my reinterpretation) that goes something like this: when you're thinking of introducing some piece of educational technology into a course design/development, ask yourself what you hope to achieve by doing so, and ask yourself whether or not you could achieve the same thing by some other method.
This was not a luddite talking, but a distinquished prof and expert in e-learning. I've thought on this many, many times. In my school, we complete around 50 curriculum projects/year and my early questions in every project are Why are we doing this? what do we hope to achieve? what's the best way to approach this course?
Just something to think on (or not).
Cheers, Chris
