Do female physics students benefit from informal physics programs they facilitate?

Gender bias, reduced sense of belonging, and lower physics self-efficacy are among the challenges faced by female students who choose to study physics. Prior studies focusing on this underrepresented group have examined the experiences and impacts of formal educational settings, leaving the impact of informal physics programs as a relatively overlooked area. Existing research on the impact of informal physics programs indicates that student facilitators, who help run the programs, can experience positive impacts on their learning and sense of community beyond the formal setting of a classroom or laboratory. In this study we took a first step, narrowing our focus to explore the relation between facilitation of informal physics programs and female students' physics identity, persistence, mindset, and worldview. We analyzed survey responses (32) and interviews (11) collected from undergraduate and graduate female students at a large, land-grant university. Our results, based on self-reported data, showed a statistically significant shift in confidence of choice of major after facilitating informal physics programs. Analysis of interviews indicated a positive effect of facilitation of informal programs on female student interest and motivation with regards to the field of physics, improved performance and competence beliefs, and the development of characteristics indicative of a growth mindset. A semantic network analysis showed statistically significant interdependencies between positive persistence and constructs including growth mindset, important early undergraduate experiences, gender stereotype threat, external recognition, and confidence.

Creating a Physicist: The Impact of Informal Programs on University Student Development

Physics outreach programs provide a critical context for informal experiences that promote the transition from new student to contributing physicist. Prior studies have suggested a positive link between participation in informal physics outreach programs and the development of a student's physics identity. In this study, we adopt a student-focused investigation to explore the effects of informal programs on dimensions of physics identity, sense of community, 21st century skill development, and motivation. We employed a mixed methods study combining a survey instrument (117 responses) and interviews (35) with current and former undergraduate and graduate students who participated in five programs through a physics and astronomy department at a large land-grant university. To examine interviews, we employed a framework based on situated learning theory, transformative learning theory, and the Dynamic Systems Model of Role Identity. Our findings, based on self-reported data, show that students who facilitated informal physics programs positively developed their physics identity, experienced increased sense of belonging to the physics community, and developed 21st century career skills. Specifically, students reported positive benefits to their communication, teamwork and networking, and design skills. The benefits of these programs can be achieved by departments of any size without significant commitment of funds or changes to curriculum.

Informal physics programs as communities of practice: How can program structures support university students' identities?

Many undergraduate and graduate physics students participate in some form of public engagement throughout the course of their studies, often through groups supported by physics departments and universities. These informal teaching and learning programs can offer unique opportunities for physics identity development. Understanding how physics identities can be fostered will allow us to work toward a field that is inclusive of more identities. In this study, we build on previous work to investigate student-facilitator experiences in three informal physics programs using an operationalized Communities of Practice framework. Through our analysis, we identify different structures within these programs that support physics identity development.
