Wiki Basics
A Wiki works as a combination of a Word document and a Web site. The wiki can be read like any other web site, but users can work collaboratively on the content using nothing but a standard web browser.
A teacher begins a wiki on a particular topic and invites others to participate in creating the content. Each time a user makes changes to a wiki page, the revision becomes the current version, and the original document is stored.
The wiki can then track the history of the changes made to each version of the document so they can be compared side-by-side, and edits can be made or versions rolled back if necessary.
Since users come to the same place to create and edit, the need to keep track of multiple Word files and compile edits is eliminated. In addition, wikis typically include forums that let users discuss the content they’re creating. 
The Wiki has become an ideal tool for increasing the amount of collaborative work done by teachers and students. Students use wikis to share research and data while working on a group project; while faculty can use wikis to collaboratvely author lesson plans and curriculum necessary to help students meet their educational standards.
Using the wiki format helps teachers capture the students’ combined knowledge and present it in a manageable way, making it accessible to everyone. Because of this, more and more classes are writing their own textbooks built upon the wiki concept.
