A wiki is a collection of web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language. Wikis are often used to create collaborative websites and to power community websites. For example, the collaborative encyclopedia Wikipedia is one of the best-known wikis. Wikis are used in businesses to provide affordable and effective intranets and for Knowledge Management. Ward Cunningham, developer of the first wiki software, WikiWikiWeb, originally described it as "the simplest online database that could possibly work".
A blog (an abridgment of the term web log) is a website, usually maintained by an individual, with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.
The bottom line is – ‘How can you become a part of this information exchange?” The answer is very simple and free (that’s the best part.) A wiki can be started and maintained on http://www.pbwiki.com/. A blog can be started and maintained on http://www.blogspot.com/. There is abundant help and information available on both sites to get you started. Make it a class project. Use it to inform parents, fellow academics, and your students of what is happening. Just remember that a wiki can be interactive and thrives on two way communications. A blog is basically a one way fountain of information.
