While many makerspaces are created by and cater to middle-aged males, our research has found that young women enjoy engaging in a multitude of making disciplines, including those traditionally thought of as masculine such as woodworking. In the AAMASE project, we worked with participants and program staff to co-design an eight-week program focusing on introducing several making disciplines with a set of principles, activities, and tools to support youths’ agency in a community-based makerspace in the mid-Atlantic region of the United States. Most participants were African American high-school-aged young women from two out-of-school learning organizations and a private school. Making projects ranged from single-day projects, such as creating resin art pieces, to longer multi-session projects, such as making a laser engraved cutting board. We found that projects supported participants’ agency as assessed through a framework we developed consisting of five criteria (self-efficacy, personalization, connection, planfulness, and iteration) consistent with the research literature on agency. Our research found that single-day projects supported participants’ self-efficacy, personalization, and connection, and longer final projects supported their planfulness and iteration. The paper also briefly describes the researchers’ use of artifact elicitation and provides recommendations for future research on agency and for practices that support agency.
