WIKI
Wiki is a piece of server software that allows users to freely create and edit Web page content using any Web browser. Wiki supports hyperlinks and has a simple text syntax for creating new pages and crosslinks between internal pages on the fly.

Georgia Tech (ftp://ftp.cc.gatech.edu/pub/gvu/tr/2000/00-19.pdf ) has had very successful use of Wikis in curriculum called CoWeb. Used in over 120 different classes. Distinguishes several types of exercises:

- Distributed Information: Where teachers and students are sharing information, and the CoWeb’s role is to ease the collection and distribution of that information.
        
- Collaborative Artifact Creation: Where students are working to create an artifact (e.g., a collaborative paper) are using the CoWeb to gather the pieces, assemble the work, or just to coordinate the work.

- Discussion and Review: Where the CoWeb serves as a place to review something (papers, ideas, designs) and critique/discuss them.

- Other: Those uses that we don’t have a category for yet.

BLOG
A blog is similar to a wiki in that a blog can be edited online without having to use an HTML editor or FTP client. The focus of a blog (or weblog) is usually the personal expression of the owner of the blog. The genral audience of the site is usually allowed to post comments around the owner's writings, but the owner's writings remain the central theme.

Blogs: Web Journals in Education - project investigates the use of blogs to promote collaborative, intercultural writing by secondary school-aged students of English and of French.
