Bridgework: Diversity and Collaboration in an Undergraduate Preengineering Course

In this article, we draw on ethnographic findings to examine the meaning of “diversity” and “collaboration” within the context of an undergraduate preengineering course at a large Hispanic-serving institution located on the U.S.–Mexico border. Using bridgework, a new theoretical concept, we analyze interactions and interactivity that occurred within and among jigsaw groups attempting to solve mathematical problems as part of a precalculus review. Our use of bridgework, contributes to cultural-historical activity theory to demonstrate how contradictions and multivoicedness among interacting activity systems can work to change patterns of activity, thus providing a complex view of diversity and collaboration.
