Many graduate public affairs programs offer both residential and online options for students. One of the challenges for multi-format programs is creating a sense of belonging among online students who may never set foot on campus. In 2017, the MPA program at the University of North Carolina at Chapel Hill developed an "immersion" course designed for residential and online students in a weekend intensive format on campus to help create a greater sense of connectedness and satisfaction among (principally) online students, while benefiting students in both formats. This paper examines immersion courses as one strategy to address gaps in belonging and satisfaction between online and on-campus students. The case study of UNC-Chapel Hill developing the immersion course and the first three iterations of it are described, offering practical insight for other campus-based public affairs programs that also have online degrees who may want to try something similar.
