When you hear the word “Wiki” are you still a bit confused? In Hawaiian “wiki” means “quick” and if you need to know more than that there are a lot of good tutorials available on the web. A useful one that I recently came across, that is available in QuickTime video, can be found here. Meredith Farkas, Distance Learning Librarian, Norwich University, does a great job at explaining wikis in general as well as demonstrating several different applications. The archived presentation carries a “library” focus but don’t let that dissuade you, Meredith does a good job showing you some best practices in wiki usage and discusses software choices. Definitely worth a look if you haven’t used a wiki before. Mederith has also posted her slides in PDF format.
The largest application of a wiki is Wikipedia.org and if you are interested in that check out a previous posting I’ve made on the topic.
