This research commentary argues for more research that attends to the processes of organizational change in mathematics departments. It outlines both the ways that research on organizational change can benefit scholarship in mathematics departments, and how mathematics education researchers are needed to develop theories of change that are contextualized to the teaching and learning of undergraduate mathematics. This commentary closes with a research agenda for moving this emergent field of study forward. This agenda involves applying change theories to historical, ongoing, and new change projects in mathematics departments, while simultaneously attending to issues of equity and social justice.
