Wikis are simply Web sites that provide easy-to-use tools for creating, editing, and sharing digital documents, images, and media files. Multiple participants can enter, submit, manage, and update a single Web workspace creating a community of authors and editors. Wiki projects help young people shift from being "consumers" of the Internet to creators on the Web. Wikis are effective in promoting collaborative learning within classes, between classes, among schools, with parents, and with communities. Wikis involve learners in asking increasingly sophisticated questions about a topic. (Contains 5 figures.)
