According to Leuf and Cunningham, a wiki is "a free expandable collection of interlinked webpages, a hypertext system for storing and modifyinh information, a data base, where each page is easily edited by any user." A Wiki can be thought of as a combination of a web site and a Word document. At its simplest, it can be read just like any other web site, with no access privileges necessary, but its real power lies in the fact that groups can collaboratively work on the content of the site using nothing but a standard web browser. The Wiki is gaining traction in education as an ideal tool for collaborative work.
Connected Learning is " when you are pursuing knowledge and expertise around something you care deeply about, and you're supported by friends and institutions who share and recognize this common passion or purpose".
