My research with CELF focuses on children's socialization to and through their material environments through language.  How do children learn to use and share objects in their surround?  How do families create local patterns of consumption and discard?  By drawing on the CELF video-ethnography of family interaction and the extensive collection of photographs and diagrams of family homes, I hope to investigate how young people learn stances towards the natural environment and to the economic systems in which families are embedded.
