Wikis, wikis, wikis. This thing is when we get to set up our own wikis. Here's one that I've established. The first page is about promethean boards. However, the real theme behind the wiki could very easily be professional development. The difference between a wiki and a blog is that the wiki allows for collaboration. Others could add to the page. Teachers who know how to use the promethean board could add their own tips and tricks. This could allow for teachers to take ownership of the page. That could increase the usage and usefulness of the page.
