In this article, we describe how technical communication students explored user advocacy and coalitional action by creating trauma-informed, intimate partner violence (IPV) awareness campaigns for our campus. The nature of this project required us to develop a trauma-informed approach to teaching at the undergraduate level. To create a supportive community of practice for instructors and students, we used a lesson study methodology in which a team of teacher-researchers collaboratively designed, observed, analyzed, and revised a sequence of lessons. We provide the larger context for our lesson study project, the lesson study structure including preparatory material for students, trauma-informed teaching strategies, and reflections on the lesson. To effect meaningful change and learning, we needed to have difficult conversations with students; this required us to acknowledge the presence of trauma in the classroom and then work to support the students who have experienced trauma. Finally, we offer a reflective critique of our experience as a heuristic for instructors to use as they implement and reflect on trauma-informed pedagogy in their own classes.
