To foster and better understand collaboration in the Scratch Online Community, we created Collab Camp, a month-long event in which Scratch community members form teams (�collabs�) to work together on Scratch projects. Our goals include: analyzing how different organizational structures support collaboration in different ways; examining how design decisions influence the diversity of participation in collaborative activities; and studying the role of constructive feedback in creative, collaborative processes. (Collab Camp was a collaboration with Yasmin Kafai's research group at University of Pennsylvania.)
