Culture has been commonly used in science education research, in particular to examine issues of equity for students from low-income, racial, and ethnic minority communities. It has provided a lens with which to appreciate science classrooms as cultural places and to recognize the importance of students' cultural ways of being as resources for science learning. Scanning the ways that "culture" has been used in recent publications shows that much science education research continues to draw from an older view of culture(s) as a bounded and coherent set of beliefs and practices associated with a distinct social world, referred to as a pluralizable or discontinuous view of culture. This view of culture has been critiqued on the basis of its assumptions of homogeneity of groups and as masking the role of systemic inequity in the marginalization of people from certain communities. This view of culture is often associated with a particular set of metaphors, such as cultural borders, gaps, mismatch, conflict, and tension. Despite increasing attention in science education research to an alternative view of culture as porous and emergent, these newer ways of thinking about culture do not yet seem to have been taken up in research around science teacher preparation. Recognizing the usefulness as well as the limits of the older view of culture as bounded and coherent social worlds, this paper points to other metaphors about culture--such as funds of knowledge, third space, and figured world--that might be more helpful in preparing science teachers. By exploring the metaphors we use to think about culture and how they structure the inferences and actions of teachers and researchers alike, we can envision new avenues of research and practice that will inform the preparation of science teachers for the complexity of our schools and classrooms.
