Have you used wikis yet?
A wiki is a website which allows users to add and edit content collectively.
One wiki that you might like to look at is the Desert Park Education Wiki which will help you to plan educational visits to the Desert Park and to share resources with other teachers.
Another is Eduwiki. Eduwiki is a collaborative partnership between educators across the world that enables us to instantly share ideas, resources, projects, and more importantly to connect to one another. The wiki talks about various digital tools and how members of the wiki find them useful in their classrooms.
Recently a group of NT teachers, some in Darwin and others in Alice, came together via a wiki to work on Re-thinking Waste in Schools. To find out more about this project visit the Rethinking Waste wikispace
