If one is exploring how to join Communities of Practice, University of Washington host an extensive grouping. The target appears to be those students/professors who either learn differently or teach those who learn differently. I could not find something similar on BSU's website.
Students were supposed to put the title of the class into action and they were to pick a cause or issue that they cared about and use social media. This was a great way to have the students actually see what was out there and to get involved rather than just learn from books.
The DO-IT Center's goal is to empower people with disabilities through technology and education. There are a wealth of resources here, some of which are specifically geared towards students and educators. They promote awareness and accessibility in both the classroom and the workplace.
