What's+a+Wiki?

//"In using wikis, students are not only learning how to publish content; they are also learning how to develop and use all sorts of collaborative skills, negotiating with others the to agree on correctness, meaning, relevance, and more. In essence, students begin to teach each other."// (Richardson, 2005, p.19)

What is a Wiki?
A wiki is a web site that lets any visitor become a participant: you can create or edit the actual site contents without any special technical knowledge or tools. All you need is a computer with an Internet connection. A wiki is continuously “under revision.” It is a living collaboration whose purpose is the sharing of the creative process and product by many. One famous example is [|Wiki-pedia], an online encyclopedia with no “authors” but millions of contributors and editors. The word "wiki" comes from Hawaiian language, meaning "quick" or "fast."

**//What is the difference between a wiki and a blog?//**
A blog, or web log, shares writing and multimedia content in the form of “posts” (starting point entries) and “comments” (responses to the posts). While commenting, and even posting, are open to the members of the blog or the general public, no one is able to change a comment or post made by another. The usual format is post-comment-comment-comment, and so on. For this reason, blogs are often the vehicle of choice to express individual opinions. A wiki has a far more open structure and allows others to change what one person has written. This openness may trump individual opinion with group consensus.
