If you have not visited Edutopia, you should. A wonderful resource for different and innovative ways of teaching and learning. Some of the resources/topics that I find particularly useful are on project based learning, assessments and technology integration. However, there is a topic for every educator for every grade level. Visit Edutopia and join its learning community!

When I visited Cool Tools for Schools, I thought it was the place for learning about Web 2.0 tools. Thanks to Diigo, I have learned about another site that has information about Web 2.0 tools. This wiki, titled WebTools4U2Use, is designed by a school librarian for school librarians. However, educators from all disciplines can use this site. This wiki is very interactive: you can click on a tool, listen to music, and leave a note! In addition, this particular wiki features a page titled Finding the Right Tool. This page helps educators find the right tool according to the task, learning and cognitive style. This wiki is pretty cool!
