Teachers, gamers, journalists, bloggers and tech wizards – almost anyone creating and sharing knowledge online – can participate in a competition for $2 million worth of grants, announced by the University of California Humanities Research Institute. The competition is supported by the John D. and Catherine T. MacArthur Foundation’s $50 million Digital Media and Learning initiative. The competition will help find ways to use social networks like MySpace as educational tools for young people, said David Theo Goldberg, director of UCHRI and professor of comparative literature at UC Irvine.
