Wiki

A wiki is different than a blog because you can change the information that someone put on the wiki. You cannot change what is posted to a blog, you can only comment on it. If someone chooses to read your comment than you can make your point about the information. If no one reads your post than the original blog stands. On a wiki you can write your comment on the wiki page and everyone will see it when the wiki is opened. If someone doesn't like your comment they can change it. A wiki would be good for group projects where several members of the group can add information for everyone to see. Two problems I see with that are: someone in the group could change what another person added and the new information may be incorrect. Another problem might be one or two people in the group doing all of the work. You might want to have each person sign what they add. A blog would be better for individual projects or assignments that are ongoing in nature. One problem with that is if it is a research project that everyone is working on, people may wait and read someone's blog and copy the information to their own blog. The nice thing about the blog is everyone in class can read it and comment on it. You could use it like a brainstorming activity also. Some students might be more likely to add their input on the computer rather than out loud in class.
