abstract: Many college campuses institute residency requirements intended to provide intentional support, engagement, and assistance in the transition into life as a first-year college student. However, first-year students opting to continue living at home with family and commuting to campus each day has become a growing trend. This group of students can often be more sizable than some may assume and their developmental needs can be consistent with those of their on-campus peers. The objective of this mixed-methods action research study was to better understand how peer-to-peer experiences and opportunities are perceived and to describe and explore the concept of social capital and sense of belonging within the first-year commuter student population. This feeling of isolation can often expand to a lack of campus involvement and engagement in social opportunities. As a result of the perceived needs of this growing first-year commuter student population, a peer mentoring program was launched as a pilot to localize, personalize, and support students by providing a peer student leader in the form of a commuter peer mentor (CPM). Results from the qualitative and quantitative data collected as a part of this study demonstrated that first-year students value specific and easily-identified resources made available to their unique need cases and while many first-year commuter students may feel well supported and connected academically, they articulated challenges with social connections within the university setting. The understandings gained from this action research can inform higher education and student affairs practitioners as they seek to establish or improve programs, resources, and practices that intentionally and thoughtfully support first-year commuter students. / Dissertation/Thesis / Doctoral Dissertation Leadership and Innovation 2020
