Abstract: This Pilots and Feasibility project, Community Pop-Up STEAM Studios, focuses on revealing the Learning Practices of Making processes through informal science education (ISE) series of art-inclusive, pop-up makerspaces in a high-poverty, primarily rural county in the US southwest. The project goals include promoting a participatory culture to leverage community funds of knowledge, individually and collectively, to address community-identified and designed challenges, and to explore the learning practices of making in Pop-Up STEAM Studio participants. Informed by museum pop-ups, the STEAM Studios were temporary workshops in a designated locale based on needs and desires of citizen stakeholders and informed by experts that focus on relationships, sharing, and communication with the capacity to cross sometimes siloed boundaries of science and art. The project adapted the pop-up concept through two participatory, socially-inclusive approaches: One Book, One Community, a national public library program, and the participatory pedagogy of negotiated learning from Reggio Emilia, Italy. Multigenerational participants explored solar energy through the functional and artistic design of solar lanterns. Facilitators documented the process through surveys and digital stories finding which Learning Practices of Making occur at different points in the making process. Findings also indicate a sense of satisfaction.
