I think that Web 2.0 tools would be a good way to get peer feedback on projects or papers. It could be useful to use blogs as a discussion starters in the classroom. Wikis could be a place for teachers to get ideas for class trips or things that the class should be like in the next semester. The classroom space could become more interesting for students and more interactive. The use of Web 2.0 ideas could be the next step in educational systems.
