For a forum to explore the educational potientials of Mobile Learning (of which I believe AR is the most promising approach) go to the blog
CIRCL is the Consortium for Innovation & Research in Converged Learning.
A global community of practice whose members share their research and innovation in converged technology to enhance learning. We encourage you to sign up to participate in the great discussions here, to receive event notifications, and to find and connect with colleagues.CIRCL is a free community-supported network. We especially hope that those involved in mobile learning and all other forms of converged learning find this a supportive community and a comfortable place to start being part of the digital dialog. It is also our hope that researchers, professors, teachers and other education professionals will be able to connect with people who are engaged in similar mobile and converged learning practice and research. To prevent spammers, we require membership requests to be approved by an administrator. While your membership is pending you are welcome to peruse the site and attend events!
