Wikis

The most popular Wiki is wikipedia, an online encyclopedia that is freely written and edited by multiple authors. More generally speaking, wikis are websites that have multiple authors. The information is not copyrighted and all edits are kept track of- a history provided for every change made.
Making a wiki is actually a lot like making our websites but also seems to combine some elements of a class blog, where students can post responses to things other students contribute. The biggest difference is that instead of responses, the input of other students is actually incorportated into the original. Chris said something that seemed like a helpful metaphor: you build a house but keep all the scaffolding on and you can just keep adding new rooms, changing things around constantly with no real hassle.
The most interesting use of a wiki that I learned about was a WikiBook. Your students could make a Wikibook about the topics covered all year. VERY COOL! They basically write their own textbook. Obviously a few issues pop up, besides the typical censoring inappropriateness. Organization is a toughie. But you could go in and at least make an initial set up, in an outline format, and the students could provide the "meat" of the wiki, which other students can correct and improve upon. I love this idea and can't wait for the day that all my students have internet access and I could actually do this as a class project. My various students over the course of years even! could work on it!
