I explore questions about the socio-cultural dimensions of learning and development in everyday and intergenerational contexts. In one line of work I examine the practices that children and families use to reason and build knowledge about the natural world. I am particularly interested in (1) how families coordinate attention and observation while participating in science activities, (2) how mobility and place structure activity and (3) cultural variability in sensemaking practices such as question-asking and explaining. I also investigate Native American participation in STEM and cultural models of self as related to senses of capability and competence. Across my scholarship, I take a participatory approach and employ a variety of research designs and methods including: community-based design research, cognitive tasks, studies of everyday practices, content analysis, discourse analysis, interaction analysis and video-ethnography. Through my work I aim to answer basic research questions about development, innovate methods, and design teaching and learning tools that contribute to the goals and well-being of Indigenous and non-dominant communities.
