This paper focuses on the undergraduate experiences in computer sciences (CS) disciplines of eight Native women and two-spirit undergraduates and how their values and experiences around the communal goal of giving back enable them to persist in computing. The paper draws from a one-year study that included participants across the U.S.A from predominantly White institutions, Native serving institutions, and tribal colleges. Utilizing the decolonizing and participant-centered methods of photo elicitation, our interviews used photographs taken by participants as starting points for conversations. This method resulted in deep understandings of participants' experiences of the supports and barriers in their CS programs, and of the importance of giving back for persistence. We adapt Page-Reeves and colleagues' 2019 framework for giving back and Native students in STEM--particularly the concepts of giving back as a Native value and giving back in the context of CS education--to illuminate the ways in which participants persisted and navigated their identities as Native students and emergent computer scientists. We also introduce a new concept, culturally connected giving back, to describe the ways in which Native undergraduates in computing contributed, or planned to contribute, towards technology sovereignty and cultural preservation. CS, like many STEM fields, is typically viewed as highly individualistic and not aligned with communal goals of helping others. However, Native participants in this study identified computing as having the potential for giving back. They incorporated a broad range of giving back actions into their computing professional identities through teaching, mentoring, serving as role models, creating counterspaces, or preserving their cultures using their computing skills. Through giving back, participants fulfilled a sense of obligation to their communities or counteracted negative stereotypes about Native learners. Beneficiaries of these acts of giving back included Native and other minoritized peers, younger students, home communities, and other Native communities. Importantly, opportunities to give back served as strong motivators to persist in CS in spite of challenges. We discuss the implications of these findings for policy and practice and also explore the implications for how institutions and CS departments can support Native student recruitment, retention, and success.
