Tom Daccord, my partner at EdTechTeacher, and I recently made a series of professional development videos with McGraw Hill for their new Social Studies program Networks. I'll post them here over time, and the whole collection can be found at http://vimeo.com/edtechteacher/videos/sort:newest.
One of the really fun parts for me was that the producer of the videos was Liz Walker, one of the last-of-the-breed TV News anchors from the Boston area, and a really wonderful lady. A figure from my childhood.
