Paper presented as part of symposium. 

Amongst efforts to realize computer science (CS) for all, recent critiques of racially biased technologies have emerged (e.g., facial recognition software), revealing a need to critically examine the interaction between computing solutions and societal factors. Yet within efforts to introduce K-12 students to such topics, studies examining teachers' learning of critical computing are rare. To understand how teachers learn to integrate societal issues within computing education, we analyzed video of a teacher professional development (PD) session with experienced computing teachers. Highlighting three particular episodes of conversation during PD, our analysis revealed how personal and classroom experiences—from making a sensor-based project to drawing on family and teaching experiences—tethered teachers’ weaving of societal and technical aspects of CS and enabled reflections on their learning and pedagogy. We discuss the need for future PD efforts to build on teachers’ experiences, draw in diverse teacher voices, and develop politicized trust among teachers. 

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. 

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.
