    Sociologists and historians of science have documented the salience of meritocracy and technocracy in engineering (Cech, 2014; Slaton, 2015; Riley, 2008). Meritocracy is often paired with a technocratic ideology, which distinguishes technical and “soft” skills and assigns more worth to the technical. Scholars have shown how technocracy and meritocracy contribute to marginalization within engineering education (Slaton, 2015; Foor et al., 2007; Secules et al., 2018). Our team has been iteratively redesigning a pedagogy seminar for engineering peer educators to disrupt such forces of marginalization. We study peer educators because they can do harm if these ideologies aren't challenged, and they have the potential to disrupt these ideologies. Using tools from discourse analysis and the ideology-in-pieces framework (Philip, 2011), we analyze how technocratic stances are reproduced or challenged in engineering peer educators’ talk. Such analyses can help others to recognize technocratic reasoning and see some of its negative consequences.

    Computational Thinking (CT) is increasingly being targeted as a pedagogical goal for science education. As such, researchers and teachers should collaborate to scaffold student engagement with CT alongside new technology and curricula. We interviewed two high school teachers who implemented a unit using dynamic modeling software to examine how they supported student engagement with CT through modeling practices. Based on their interviews, they believed that they supported student engagement in CT and modeling through preliminary activities, conducting classroom demonstrations of the phenomenon, and engaging students in model revisions through dialogue.

    As human society advances, new scientific challenges are constantly emerging. The use of systems thinking (ST) and computational thinking (CT) can help elucidate these problems and bring us closer to a possible solution. The construction and use of models is one of the most widely used tools when trying to understand systems. In this paper, we examine four case studies of student pairs who were engaged in building and using system models in an NGSS-aligned project-based learning unit on chemical kinetics. Using a theoretical framework that describes how CT and ST practices are manifested in the modeling process we examine the progression of students’ models during their model revisions and explore strategies they employ to overcome modeling challenges they face. We discuss some suggestions to scaffold students’ progression in constructing computational system models and prepare teachers to support their students in engaging in CT and ST practices.

    There is broad belief that preparing all students in preK-12 for a future in STEM involves integrating computing and computational thinking (CT) tools and practices. Through creating and examining rich “STEM+CT” learning environments that integrate STEM and CT, researchers are defining what CT means in STEM disciplinary settings. This interactive session brings together a diverse spectrum of leading STEM researchers to share how they operationalize CT, what integrated CT and STEM learning looks like in their curriculum, and how this learning is measured. It will serve as a rich opportunity for discussion to help advance the state of the field of STEM and CT integration.

    When designing an instructional tool and using it in pedagogical activities, it is essential that designers and users understand what pedagogical affordances and constraints the tool provides to support its successful integration into targeted pedagogical activities. Toward this end, we developed Pedagogical Affordance Analysis (PAA). PAA involves analyzing teachers’ Pedagogical Content Knowledge and/or Technological Pedagogical Content Knowledge to elicit pedagogical affordances and constraints that are specific to a given instructional goal. Information obtained through PAA can help in designing, refining, and/or evaluating instructional tools. We present a case study in which we used PAA to successfully design a visual representation for middle-school algebra. To the best of our knowledge, PAA is the only available systematic method that leverages teachers’ pedagogical knowledge in identifying pedagogical affordances and constraints. PAA can be used across a wide range of existing tools and prototypes of to-be-designed tools.

    teration is a central practice in art and science; however, it has yet to be deeply explored in STEAM learning environments. This study adopts a sociomaterial orientation (Fenwick and Edwards, 2013) to characterize the nature of iteration in one STEAM activity, an Optics Design Challenge, with informal educators. We found that iteration emerged as “microcycles” of interactions, specifically as adjustments, additions, and negotiations in both material artifacts and the narrative.
