The John D. and Catherine T. MacArthur Foundation Series on Digital Media and Learning is founded upon the working hypothesis that those immersed in new digital tools and networks are engaged in an unprecedented exploration of language, games, social interaction, problem solving, and self-directed activity that leads to diverse forms of learning. The John D. and Catherine T. MacArthur Foundation Reports on Digital Media and Learning present findings from current research on how young people learn, play, socialize, and participate in civic life. The Reports result from research projects funded by the MacArthur Foundation. Both the Series volumes and the Reports are available online at the MIT Press.
