In this paper, we present the development of a "reconstruction kit" for e-textiles, which transforms fixed-state construction kits---maker tools and technologies that focus on the creation of semi-permanent projects---into flex-state construction kits that allow for endless deconstruction and reconstruction. The kit uses modular pieces that allow students to both solve and create troubleshooting and debugging challenges, which we call "DebugIts." We tested our prototype in an after-school workshop with ten high school students, and report on how they interacted with the kit, as well as what they learned through the DebugIt activities. In the discussion, we delve into the affordances and challenges of using these kits as both learning and assessment tools. We also discuss how our pilot and prototype can inform the design of reconstruction kits in other areas of making.

A Redesigned Reconstruction Kit for Rapid Collaborative Debugging and Designing of E-Textiles
In this paper, we present an iteration on a “reconstruction kit” for e-textiles, a flexible-state construction kit that allows for rapid deconstruction and reconstruction of sewn, programmable circuits. The reconstruction kit was redesigned to be more modular and was tested in more computationally and spatially challenging debugging and design situations. by four pairs of˛ students familiar with e-textiles taking an introductory computer science course in a U.S. high school. Analyzing think-aloud protocols of the four sessions, we examined affordances and limitations of how student debugged and designed with the reconstruction kit and in which ways collaborative interactions were supported.

Debugging, a recurrent practice while programming, can reveal significant information about student learning. Making electronic textile (e-textile) artifacts entails numerous opportunities for students to debug across circuitry, coding, crafting and designing domains. In this study, 69 high school students worked on a series of four different e-textiles projects over eight weeks as a part of their introductory computer science course. We analyzed debugging challenges and resolutions reported by students in their portfolios and interviews and found not only a wide range of computational concepts but also the development of specific computational practices such as being iterative and incremental in students’ debugging e-textiles projects. In the discussion, we address the need for more studies to recognize other computational practices such as abstraction and modularization, the potential of hybrid contexts for debugging, and the social aspects of debugging.more » « less

Abstract Electronic textiles (e‐textiles) that combine the wearing comfort of textiles and the functionality of soft electronics are highly demanded in wearable applications. However, fabricating robust high‐performance stretchable e‐textiles with good abrasion resistance and high‐resolution aesthetic patterns for high‐throughput manufacturing and practical applications remains challenging. Herein, the authors report a new multifunctional e‐textile fabricated via screen printing of the water‐based silver fractal dendrites conductive ink. The as‐fabricated e‐textiles spray‐coated with the invisible waterproofing agent exhibit superior flexibility, water resistance, wearing comfort, air permeability, and abrasion resistance, achieving a low sheet resistance of 0.088 Ω sq−1, high stretchability of up to 154%, and excellent dynamic stability for over 1000 cyclic testing (ε = 100%). The printed e‐textiles can be explored as strain sensors and ultralow voltage‐driven Joule heaters driven for personalized thermal management. They finally demonstrate an integrated aesthetic smart clothing made of their multifunctional e‐textiles for human motion detection and body‐temperature management. The printed e‐textiles provide new opportunities for developing novel wearable electronics and smart clothing for future commercial applications.more » « less
