National Commission on Teaching & America's Future project with 9 university partners to "make educator development more collaborative and to give new teachers a stronger start in the profession".
Lots of money apparently. Use edweb.net - a "free social networking platform especially designed for educators".
A mish-mash of comments to a query about the effectiveness of "using online learning tools to deliver teacher professional learning programs".
Related, but a very different focus/approach to what I see PSTN doing, but there does appear to be some overlap in the literature etc.
Haven't read it yet, however, it seems to be one of the key Australian reports. Have a feeling that PSTN can help bridge some of the gaps and problems that will be mentioned. Will update.
