As many institutions of higher education increase STEM offerings, the impact can be more pronounced at liberal arts colleges, because the growth in STEM typically results in new construction or renovation in their only science building. The construction of new space is most challenging in organic chemistry, where the number of fume hoods per section is a unique pedagogical requirement. To avoid disrupting a department entirely during construction, an institution can encourage students to take a course elsewhere—at a community college or nearby university partner—or to plan their schedule to avoid the downtime. But this reduces only the number of sections, not the entire need, because maintaining the faculty’s teaching ability and course’s availability to students are critical to the institutional mission. The solution is to find or create swing space.
