The middle school partnership in the geometry working group is working on developing graphical representations of the Pythagorean Theorem in Geometer's Sketchpad. Two of the members are working on several proofs of the theorem. Two of the members of the group are working on developing pages in Sketchpad that is the preperatory work leading up to the proofs. Some of these ideas are coming from the Looking for Pythagoras unit in CMP.
The other group is working on a constructivist approach to Geometry using GSP (and maybe other software). The group began working on a template for overarching questions in a geometry class. A few of the resources that were looked at include: A Euclidean Geometry course using GSP: http://www.calvin.edu/~venema/eeg/eeg.html
An article addressing the "big picture" discussion we've been having: http://investigations.terc.edu/library/bookpapers/geometryand_proof.cfm
