Oops, I had forgotten that October is Connected Educator’s Month.
Connected Educators is an initiative of the Office of Educational Technology at the U.S. Department of Education and is conducted by the American Institutes for Research in collaboration with several partner organizations and a technical working group. Numerous other organizations and individuals have contributed to its success as organizers and participating organizations in Connected Educator Month.
Connected Educators pursues this mission through seeking to understand and promote educators learning and collaborating through online communities of practice and social networks.
You can find some older, but still useful, resources at The Best Resources For Connected Educators Month.
