In this article, we chronicle our experience in team-teaching large-lecture sections of “Introduction to American Government.” A dual-instructor approach allows us to accommodate 250 students, which obviates the need for five separate sections (and instructors) of the course. In addition, our “Crossfire Approach,” in which we engage one another in frequent and unstructured political debate, generates student interest in the course and in the political science major. Students who were enrolled in this course from 2007 through 2011 were significantly more likely to declare political science as their major than those who took it from any other instructor or either of us teaching it individually. This approach conserves departmental resources while simultaneously growing the program—a clear win-win situation.
