Wikis in the classroom

Using wikis is a good idea as well but the students would have to be in fourth or fifth grade probably to be able to understand the concept. I think the students would like to research and make their own website kind of as a class. The teacher could give them a topic to research and they would have to research it and maybe write a few sentences about it. And then another day or night for homework have them look at someone elses post and make sure it is correct. This seems like a great learning tool about effective websites and things of that nature.
