Katherine Goodman is assistant professor at the University of Colorado Denver, and the associate director of Inworks, an interdisciplinary innovation lab. She completed her PhD at the ATLAS Institute in Technology, Media, and Society at the University of Colorado Boulder. She also holds a B.S. in mathematics and a masters of professional writing.
Jean Hertzberg
University of Colorado, Boulder

Dr. Hertzberg is currently Associate Professor of Mechanical Engineering at CU-Boulder. She teaches graduate and undergraduate courses in measurement techniques, thermodynamics, fluid mechanics, heat transfer, design and computer tools. She has pioneered a spectacular course on the art and physics of flow visualization, and is conducting research on the impact of the course with respect to visual perception and educational outcomes. Her disciplinary research centers around pulsatile, vortex dominated flows with applications in both combustion and bio-fluid dynamics. She is also interested in a variety of flow field measurement techniques. Current projects include velocity and vorticity in human cardiac ventricles and large vessels.
Abstract
This work-in-progress explores the qualitative analysis of work modeled after visual expertise experiments in cognitive psychology. In this experiment, participants were asked to sort images of fluid flows as either laminar or turbulent with no prior knowledge of the categories. The two groups of participants were engineering students who had passed a Fluid Mechanics course (“Experienced in Fluids”) and students with no prior formal fluid training (“Novice in Fluids”). This experiment included an open-ended inquiry of participant understanding of the task they were performing. (The quantitative outcomes of this experiment are in a forthcoming publication.) We briefly describe the experiment overall, and then delve into how the quantitative results can be explored further through the two open-response questions participants answered at the end of the experiment. Here, we discuss initial coding and exploratory analysis of responses from both participant groups to the following questions: Thinking about your experience in the experiment, how would you describe the two categories of images? and How did you decide which images to place in which category? We conclude with insights for improving the use of images in Fluid Mechanics courses, and broader implications of how formative assessments might be created for other courses based upon this model.
