Much of the current research on scientific literacy focuses on particular text genres read by students within the classroom context. We offer a cross-case analysis of literacy as social practice in multicultural communities around the world, through which we reveal that individuals with no formal education, as well as people with varied levels of schooling completed, customarily and actively engage in literacy events with the goal of learning about science as part of their everyday lives. We argue that these outcomes substantiate the notion that multiple ways of being scientifically literate actually exist and that scientific literacy in its most fundamental sense is crucial in science education, despite the fact that the most common definitions and notions of scientific literacy have predominantly considered its derived sense (Norris and Phillips 224).

In this methodological and theoretical article, we address the need for more cross-case work on studies of literacy in use within different social and cultural contexts. The Cultural Practices of Literacy Study (CPLS) project has been working on a methodology for cross-case analyses that are principled in that the qualitative nature of each case, with its layers of context and interpretive meaning making by the researcher, is maintained while still allowing for data aggregation across cases. We present a model of a literacy practice that emerged from this work as one that may contribute to the work of other literacy researchers who are looking for theoretically driven ways to analyze and interpret ethnographic accounts of literacy practice on a larger scale and to answer questions about literacy practice across studies. We describe our theoretically based coding scheme, as well as the development of a large ethnographic database of literacy practices data and the technical aspects of lifting ethnographic data into a large database. We also provide a description of a pilot cross-case analysis as an example of the promise of such qualitative cross-case databases.
