One source says ‘wiki’ is the acronym for “what I know is”
another says wiki is a Hawaiian word for ‘quick.’
A wiki is a collaborative website that allows users to add and edit content easily. Wikis are especially good tools for sharing knowledge—for collaborating, communicating, or contributing information on a specific topic. Unlike blogs that have one identifiable author, wikis are developed around specific subject interests and may have several contributors. Anyone is allowed to add or edit content using nothing more than a web browser. Basically, users click on the edit button, make changes, and hit save.
Wikis offer a way for students to learn. They are basically online collaboration tools, where someone can post something (text, pictures, audio, video) and another person can comment on what has been posted and then write more. Wikis work best when there are numerous links to other web pages.
