The substantive and the political are part of most educational endeavors. Researchers tend to be cast as more powerful in interactions between research and practice. This structural historical hierarchy is at the backdrop of research-practice partnerships (RPP) and threatens to marginalize practitioners' perspectives. Drawing on Bakhtin and…

This special issue joins the recent but growing effort to expand knowledge in the learning sciences, by examining the notion of participation in teacher-researcher collaborative design (co-design). Co-design is not just a means to an end; it is a context where professional learning happens. Each of the seven papers describes teacher-researcher…

Mobility provides the fabric of everyday life but is rarely considered part of learning and is almost never used as relevant, experiential content in teaching. This special issue integrates ideas and efforts across different fields into a more unified framework to study and design for what we call Learning on the Move. Approaches used in these…

This essay examines the role of public education in the process of place-remaking that relies on a false separation between teaching and issues of race, politics, and power. I construct a historical case study of my hometown that presents a counter narrative, presented by students, of race and legacy in the context of a public school and the…

What responsibilities do researchers of learning have in the wake of Trump's election and the proliferation of far-right, populist nationalism across the globe? In this essay, we seek to prompt and engage a dialogue about the political role and responsibilities of our field at this historical moment. First, we situate the social hierarchies that…

This commentary focuses on the ways the set of articles in this issue, taken together, engage an important and much needed conversation in design-based approaches to inquiry: that is, what does it mean to do work in and with nondominant communities? Drawing on cultural historical activity theory, decolonizing methodologies, and indigenous…

This article addresses how we can develop learning environments that establish a need for scientific practices and provide a context for developing content knowledge through practice. It argues that Pickering's (1995) notion of "The Mangle of Practice" informs these efforts by focusing our attention on how resistance, or push-back from…

New media, new knowledge practices, and concepts point to the need for greater understanding of cognitive processes underlying knowledge acquisition and generation in open informational worlds. The authors of the articles in this special issue address cognitive and instructional challenges surrounding multiple document comprehension--a…

Based on a three-year-long ethnography of the hobby of model rocketry, I present a practice-centered theory of interest relationships--that is, the pattern of long-term, self-motivated engagement in open-ended practices that has been theorized under the concept of "individual interests". In contrast to extant theories of individual interests, in…

In this article, the author wishes to emphasize two fundamental points related to theory that were significantly underplayed in Simon et al.'s "A Developing Approach to Studying Students' Learning through Their Mathematical Activity" (2010). The author believes these points are central to any study of children's mathematical learning. The first…

This article describes the development of the Precalculus Concept Assessment (PCA) instrument, a 25-item multiple-choice exam. The reasoning abilities and understandings central to precalculus and foundational for beginning calculus were identified and characterized in a series of research studies and are articulated in the PCA Taxonomy. These…

Son and Goldstone (2009) provided orienting activities intended to increase personal engagement, and these activities reduced participants' transfer based on concepts of signal detectability theory. I offer a theoretical interpretation that differs from theirs. First, instead of assuming that activity is contextualized in some conditions and not…

There are many meanings of "scientific reasoning" or "scientific inquiry" in use, and many corresponding orientations toward its enhancement and tracking. Deciding what these terms mean once and for all is an elusive and likely chimerical goal. However, setting down some core models might help in being clear on where different researchers stand…

A group of high school students created a drawing of a circle using a device called the Drawing Machine. To describe their experiences, we propose an alternative to the idea that to master a tool one must create a mental version of the tool. We suggest, instead, that as students change their relationships to a tool over time, their lived-in spaces…

Chi (2005) proposed that students experience difficulty in learning about physics concepts such as light, heat, or electric current because they attribute to these concepts an inappropriate ontological status of material substances rather than the more veridical status of emergent processes. Conceptual change could thus be facilitated by training…
