In sticking with the Wiki theme, Wikinews looks like a project with some constructivist potential for classroom teachers. Not that they’ve set their goals very high or anything:
We seek to promote the idea of the citizen journalist, because we believe that everyone can make a useful contribution to painting the big picture of what is happening in the world around us. The time has come to create a free news source, by the people and for the people. We invite you to join us in this effort which has the potential to change the world forever.
Ok, so let’s think about this…a news feed that is created by communities of reporters each of whom can add sourced content to flesh out the story. There is a review process by which the information is vetted. You have published articles where corrections can be made for a period of time. And they are archived for future reference.
How cool would it be to create such a space in a school, where anyone could contribute what they know that can be verified, and where accuracy is pursued post publication? What would that teach about journalism…since reporters don’t really need to go to J-school anymore anyway?
