I’m very happy to be able to link to “Mashing Congress,” the article that Jesse Silva and I wrote for Dttp: Documents to the People, detailing our wiki mash-up tool for Congressional research. (ALA login required, rassenfrassen.)
If you’re not interested in Congressional research (and who isn’t?) I think this is still an interesting application for wikis and screencasts. Basically, we used a wiki framework to open screencast tutorials simultaneously with live database windows for learners to practice their skills in. No frames, no clicking back and forth between windows. A little bit of scrolling may be required, depending on your monitor size. But generally speaking, a more immediate and elegant way to provide active learning opportunities (read: hands-on practice) and feedback for your tutorial users.
Thanks, Jesse! And thanks, DttP!
