DebateGraph

Debate Graph is a "cloud-based service that offers individuals and communities a powerful way to learn about and deliberate and decide on complex issues. It does so by enabling communities of any size to externalize, visualize, question, and evaluate all of the considerations that any member thinks may be relevant to the topic at hand – and by facilitating intelligent, constructive dialogue within the community around those issues."

This media allows students to create a visual graphic organizer of their thoughts and argument. They can share it for a global perspective, or just use it on their own. There are a lot of possibilities. For more ideas, check out the graphic organizer on Ways to Use Debate Graph.  Links to an external site.

This is a free service, but does require a subscription and email address to use and share the service.
