Web 2.0: Wiki Research

How can a wiki be used in a current class on your schedule (not this course)? Pick a class and be specific how the class could create and use a Wiki on a regular basis (tip: Use the Internet, here is a good source).
Wikis can be used for Biology class to make study guides with everyone in the class participating. Everyone can put what they each think will be on the test to get the perfect study guide. 
What are the benefits of using a wiki in class

• Everyone participates
• Everyone can put what they think is correct
• The teacher can edit it

How can we create a wiki in this class, what would we contribute to it and how would we utilize it on an on-going basis?

We can make a wiki about technology news. We can talk about how technology is changing and helping us.
What experience do you have using or creating wikis?

I have worked with wikis before in Web 2.0.
