A wiki is a collection of collaboratively authored web documents. Basically, a wiki page is a web page everyone in your class can create together, right in the browser, without needing to know HTML. A wiki starts with one front page. Each author can add other pages to the wiki by simply creating a link to a page that doesn't exist yet.
Wikis get their name from the Hawaiian term "wiki wiki," which means "very fast." A wiki is indeed a fast method for creating content as a group. It's a hugely popular format on the Web for creating documents as a group. There is usually no central editor of a wiki, no single person who has final editorial control. Instead, the community edits and develops it's own content. Consensus views emerge from the work of many people on a document.
Moodle's wiki is built on top of an older wiki system called Erfurt wiki http://erfurtwiki.sourceforge.net.
In Moodle, wikis can be a powerful tool for collaborative work. The entire class can edit a document together, creating a class product, or each student can have their own wiki and work on it with you and their classmates.
Tips and tricks
- We have course filled with resources and a wiki devoted to equipment located in several remote classrooms, as an aid to instructors. I created my own page that has links to equipment and process pages that I use all the time in giving directions. The front page is organized differently than my page.
- A useful way of to start a wiki, is to think of the front page as a structured table of contents. Essentially a wiki is organized by its links.
