Our institution is, like many others, encouraging the use of technology in large lecture courses. I jumped into the deep end with the CPS clickers and think once I really learn more than basic uses that it will be really great- although I completely underestimated how awkward it would feel to stand around in front of a large class for 60 seconds while they all entered an answer. I am now contemplating the use of a GeoPad, not only in teaching but in research as well.
Geopad is "the integrated combination of GIS software, a GPS receiver, and a Windows XP TabletPC (GeoPad) or a PocketPC Personal Digital Assistant (GeoPocket)." Sounds great, but I have such little experience with this stuff and really no clue where to start. My biggest fear is that I drop a bunch of dough on some equipment that will take a ton of time to integrate. On Inside-out, based out of Lawrence University, there's a good bit of blogged info on using this technology in teaching intro environmental science courses. I'm scrounging for info and hope that once this semester reaches its final throes I'll be able to dig into this a bit more.
But I mean check it out- how cool would it be to be able to do this:
