Wikis promote collaborative thinking

Just a little note. I had an interesting example of how wikis promote collaboration today.  I was showing a group of students how they could contribute to a wiki and asked for a sample sentence in their own words to insert. A sample was offered by a student. There then followed a great debate amongst the rest of the students about how to word the sentence for publication. It only took a few minutes and the sentence went through several evolutions but the class came to a friendly consensus. The sentence was grammatically correct and although the message was the same, the amended version was more sophisticated than the original. Now, I know this took place in class, but it was the wiki that inspired the debate and the fact that the sentence was going to be online. It was really interesting to listen to the discussion, follow how the sentence evolved, why the students thought some combinations of words sounded better than others and how some of the students learnt from each other.
