A Wiki is an online discussion board that allows a certain number of people to edit and change and add information to discuss on a particular issue. Wikis need to be formatted and structured properly for them to be effective. Wikis are sort of like blogs but can be edited by a number of people providing they know the password. Other users can add comments to it and ask questions. Wikis are particularly useful in the classroom because they enable groups to come up with ideas independently, post these and then other people in the group can change or offer suggestions to these posts, they can also add points that they think are important. I think that Wikis are good however; they are hard to structure, without really thinking about the appropriate headings, they are just a jumble of posts by a group of people.
