Structural reasoning is a combined ability to "look for structures, recognize structures, probe into structures, act upon structures, reason in terms of general structures, and see how a piece of knowledge acquired resolves a perturbation experienced" (Harel and Soto, 2017). The purpose of this study was to explore the cognitive…

Physics education research over the past few decades has made significant advances toward improving instructional practices and developing effective instructional materials for physics classrooms. In some contexts, however, after multiple instructional refinements difficulties can remain persistent. Recent findings in PER suggest that many of…

Students often fail to develop a sophisticated understanding of scientific topics despite years of formal education designed to help them do so. Through studying how students learn the physical sciences, conceptual change researchers have amassed a large body of evidence that people, rather than being empty vessels who passively accept scientific…

Climate scientists agree that (a) human activity is a significant driver of recent climate change, and (b) climate change is a danger to humanity. However, the general public accepts the former point, but rejects the latter. Thus, climate experts and the general public diverge in their understanding of the relationship between humans and climate…

This dissertation examines the thesis that implicit learning plays a role in learning about scientific phenomena, and subsequently, in conceptual change. Decades of research in learning science demonstrate that a primary challenge of science education is overcoming prior, naive knowledge of natural phenomena in order to gain scientific…

Although a large part the Physics Education Research (PER) literature investigates students' conceptual understanding in physics, these investigations focus on qualitative, conceptual reasoning. Even in modeling expert problem solving, attention to conceptual understanding means a focus on initial qualitative analysis of the problem; the equations…
