Wallwisher

Wallwisher is a Web 2.0 tools that allows participants to post coments on a digital wall. This might be comments, suggestions or contributions in a class discussion or a debate. You do not need to sign up to leave a comment but you do to set one up. This would be an excellent tool in class where more subdued students do not feel comfortable adding their opinions to full class discussions. It is also a good place for collecting resources or links that the group feel relates to a topic of study to.
