How do children learn to collaborate with others? In this talk, Barbara Rogoff discusses cultural differences in children's collaboration and in supports for learning to collaborate. She argues that collaboration is a key aspect of a cultural paradigm for learning that is especially prevalent in many Mexican and Indigenous-heritage communities of the Americas, where children have wide opportunity to contribute to endeavors of their family and community. Collaboration appears to be less common and less supported in middle-class communities that segregate children from the range of activities of their community.
