Wikis are useful tools. Their main strength is also their main weakness – anyone can edit them. (I know that’s not original, I’ve read it somewhere and can’t remember where – oops) On the face of it, that might make them a bad tool for teaching/learning – we’ve all heard stories about Wikipedia being banned from being cited in a student essay, on the basis that the information might be wrong – although why that only applies to Wikipedia and not any other web page I have never understood. But there are controls for this. Looking at the history of a page will tell you who has edited it, and when. You can also restrict who can edit the page, which should (in theory) mean that you don’t get entire pages replaced with ‘I love World of Warcraft’, unless you want that of course!
It could also be a good way for us to interact with students – updating a wiki is much quicker than updating a web page, as you don’t have to go through several people and processes before getting the information online. It might not be as polished as the library web page, but if it connects people to the information that they need, does that really matter?
They’re also great for internal communication too – although we have things like shared drives and public folders, you can’t always access them. A wiki, being accessible via the web, is available anywhere, which is much handier!
