Aaron Knochel, Assistant Professor of Art Education at The Pennsylvania State University in University Park, introduced his preservice art education students to a growing field of design practice that focused on developing open source, affordable prosthetics to kids that could otherwise not afford them. Many of these projects involve three important concepts significant to art education: (1) rapid prototyping via digital fabrication; (2) a participatory design process that is enabled by connectivity and sharing; and (3) a commitment to a socially engaged practice of making that collaboratively builds ideation and social good. This article outlines the author's own experience with his students learning about 3-D printing, developing design practices that have deeply embedded participatory frameworks, and exploring the potential for art education as a socially engaged practice that combines creating and making while having positive social impact. Through the activity, the students demonstrated what it means to share and connect to ideas not only to larger online communities, but also within the classroom.
