This exploratory study compares how young people (ages 15-16) learn circuitry concepts and layout design principles important to electrical engineering using one of two educational circuitry toolkits: paper circuits and traditional solderless breadboards. Paper-based prototyping kits are representative of a trend that incorporates new materials and approaches to integrating arts into traditional STEM disciplines. Extending prior research on how non-traditional toolkits enhance learning of electrical engineering outcomes, including basic circuitry concepts (i.e., current flow, polarity, and connections), this study examines the material affordances and design choices of the kits that contribute to youth's understanding of more advanced circuitry layout design principles, including space allocation, placement of electronic components, and routing. Results indicate that paper circuits better afford the learning of layout design principles for printed circuit boards (PCBs) with large effect sizes. This study illuminates how the materials of educational toolkits uniquely solicit body- and material-syntonic patterns of activity, and thus differentially engage learners' powerful ideas around circuitry and design principles. This investigation encourages careful consideration of the material affordances of some toolkits over others for learning purposes.

The maker movement advocates hands-on making with emerging technologies because of its value for promoting innovative and personally meaningful transdisciplinary learning. Educational research has focused on settings that primarily serve youth from dominant groups, yet we know surprisingly little about making among minoritized youth and the kinds of resources that support their making. This study sought to better understand the extent to which maker practices are present in the lives of minoritized youth and the network of resources that support their engagement. In this study, we analyzed survey responses of 52 youth from an urban, under-resourced community in Chicago and conducted an inductive thematic analysis of 20 interviews through a model of connected learning. Findings showed these youth participated in a diverse range of interest-driven, low-tech maker activities in their own homes more often than in school, after school programs, or through online resources and communities (i.e., YouTube, Internet, social media). Many youths displayed different levels of participation with intergenerational support, as parents and extended family members supported youth in their hands-on making. This work opens up pathways for fostering connected learning opportunities within minoritized communities by building on existing learning experiences within home settings and supportive relationships.
