Free Collaboration Tools For All...Take your Pick!

I came across some web-based collaborative tools this weekend. These tools will not only enhance collaboration between teachers, but they are also a great way to promote student-student collaboration. If used effectively, these tools can help viualize, explore, and communicate ideas. Dabbleboard  is an online whiteboard for drawing and team collaboration. I like the way it detects common shapes when drawing.  Rey told me about SKRBL, which is another online whiteboard. CoSketch is also similar, but you don't have to register at all. These are just a few, but I will have more listed under Collaboration. As always, these are completely free, some require registration, and others do not.
