This reflective essay follows a faculty working group as they attempt to understand barriers to access to course materials through the scholarship of teaching and learning (SoTL). Through the workgroup's research and collaboration with students in a problem-based learning course, the workgroup uncovered elements of the hidden curriculum in assumptions regarding course material procurement. The collaboration has served as the foundation for efforts to begin to transform the way that faculty on campus make use of textbooks and course materials in their courses. This transformation should make explicit to faculty that the utilization of course materials for all aspects of the course are often hidden pedagogy and must be made explicit by each instructor.
