This document discusses wikis and their use in education. It begins by defining what a wiki is - a collaboratively edited website that allows all users to freely edit pages. Wikis use simple formatting and do not require specialized software. The document then discusses how teachers can use wikis to facilitate writing, collaboration on projects, and service learning. Potential obstacles for teachers include students being uncomfortable with public and collaborative writing or reluctant to contribute due to concerns about authorship and credit. The document encourages visiting wikispaces.com to create and experience a wikispace firsthand.
