In this paper, we take an in-depth look at the physics faculty and student volunteers, which we will refer to as the program personnel, involved in informal physics programs to better understand their roles and responsibilities, their interactions with audiences, and their connectedness with content and activities. Understanding the complexities between programs, personnel, and audiences allows us to look for areas to improve informal physics programs in being inclusive, in being equitable and accessible, in supporting physics students who participate, and in connecting more strongly to the
Environmental educators have used guided-inquiry in natural and supportive learning environments for decades, but comparatively little programming and research has focused on experiences in urban environments, including in constructed ecosystems like green roofs, or impacts on older youth and adults. To address this gap, we designed a tiered, near-peer research mentoring program called Project TRUE (Teens Researching Urban Ecology) and used a mixed-methods approach to evaluate impacts on undergraduates serving as research mentors. During the 11-week program, undergraduates conducted
