The following is a Theory paper that presents an ethnographic exploration into how concepts are situated in workplace and classroom settings. Situated cognition research demonstrates that different contexts wherein learning occurs and knowledge is applied shape our conceptual understanding. Within engineering education and practice this means that practitioners, students, and instructors demonstrate different ways of representing their conceptual knowledge due to the different contexts wherein they learn and apply engineering concepts. The purpose of this paper is to present themes on how practitioners, students, and instructors represent fundamental structural engineering concepts within the contexts of structural engineering design. By representation of concepts we mean the ways in which practitioners, students, and instructors portray and demonstrate their conceptual understanding of concepts through the social and material contexts of the workplace and classroom environments. Previous research on learning and engineering education has shown the influence that social and material contexts within these environments have on our knowing and understanding. The researchers use ethnographic methods consisting of workplace and classroom observations, interviews with practitioners, students, and instructors, and documentation of workplace and academic artifacts—such as drawings, calculations, and notes—to access practitioners’, students’, and instructors’ conceptual representations. These ethnographic methods are conducted at a private engineering firm and in 300 and 400 level structural engineering courses. Preliminary results indicate that instructors’ conceptual representations in the classroom aim to enhance students’ broader understanding of these concepts; whereas students’ conceptual representations are focused towards utility in solving homework and exam problems. Practitioners’ conceptual representations are more flexible and adapt to project and workplace constraints. These results seem to indicate that even when instructors emphasize broader conceptual knowledge, the academic incentives behind homework and test scores lead to more academically focused conceptual representations by students. Furthermore, practitioners’ conceptual representations indicate the necessity of conceptual fluency in the workplace, which contrasts with the rigidity of conceptual representations that students develop in the classroom. This comparison between workplace and academic conceptual representations enhances our understanding of the extent to which students, instructors, and practitioners share similar or different conceptual representations within the domain of structural engineering. This, in turn, may lead to guided curriculum reform efforts aimed at better preparing structural engineering students for their professional careers.

Characterizing Variability in Shared Meaning through Millions of Sketches
The study of mental representations of concepts has histori- cally focused on the representations of the “average” person. Here, we shift away from this aggregate view and examine the principles of variability across people in conceptual rep- resentations. Using a database of millions of sketches by peo- ple worldwide, we ask what predicts whether people converge or diverge in their representations of a specific concept, and which kinds of concepts tend to be more or less variable. We find that larger and more dense populations tend to have less variable representations, and concepts high in valence and arousal tend to be less variable across people. Further, two countries tend to have people with more similar conceptual representations when they are linguistically, geographically, and culturally similar. Our work provides the first characteri- zation of the principles of variability in shared meaning across a large, diverse sample of participants.

Abstract In visual communication, people glean insights about patterns of data by observing visual representations of datasets. Colormap data visualizations (“colormaps”) show patterns in datasets by mapping variations in color to variations in magnitude. When people interpret colormaps, they have expectations about how colors map to magnitude, and they are better at interpreting visualizations that align with those expectations. For example, they infer that darker colors map to larger quantities (dark-is-more bias) and colors that are higher on vertically oriented legends map to larger quantities (high-is-more bias). In previous studies, the notion of quantity was straightforward because more of the concept represented (conceptual magnitude) corresponded to larger numeric values (numeric magnitude). However, conceptual and numeric magnitude can conflict, such as using rank order to quantify health—smaller numbers correspond to greater health. Under conflicts, are inferred mappings formed based on the numeric level, the conceptual level, or a combination of both? We addressed this question across five experiments, spanning data domains: alien animals, antibiotic discovery, and public health. Across experiments, the high-is-more bias operated at the conceptual level: colormaps were easier to interpret when larger conceptual magnitude was represented higher on the legend, regardless of numeric magnitude. The dark-is-more bias tended to operate at the conceptual level, but numeric magnitude could interfere, or even dominate, if conceptual magnitude was less salient. These results elucidate factors influencing meanings inferred from visual features and emphasize the need to consider data meaning, not just numbers, when designing visualizations aimed to facilitate visual communication.more » « less

A foundational assumption of linguistic communication is that conversants have similar underlying concepts (Brennan & Clark, 1996; Wierzbicka, 2012). On this view, the ability of one person to understand another when she says “the tree” depends on the word activating the same concept in both people. One approach to verifying this assumption is to rely on definitions, but this reasoning is circular— how can we be sure the words in our definitions are the same? Here, we investigate the assumption of shared linguistic concepts by studying concepts represented in the visual modality—drawings—and examining predictors of their variability. Specifically, we ask whether people who are geographically closer and inhabit a similar linguistic environment produce more similar drawings.more » « less

Benton, Richard (Ed.)Sparse coding can improve discrimination of sensory stimuli by reducing overlap between their representations. Two factors, however, can offset sparse coding’s benefits: similar sensory stimuli have significant overlap and responses vary across trials. To elucidate the effects of these 2 factors, we analyzed odor responses in the fly and mouse olfactory regions implicated in learning and discrimination—the mushroom body (MB) and the piriform cortex (PCx). We found that neuronal responses fall along a continuum from extremely reliable across trials to extremely variable or stochastic. Computationally, we show that the observed variability arises from noise within central circuits rather than sensory noise. We propose this coding scheme to be advantageous for coarse- and fine-odor discrimination. More reliable cells enable quick discrimination between dissimilar odors. For similar odors, however, these cells overlap and do not provide distinguishing information. By contrast, more unreliable cells are decorrelated for similar odors, providing distinguishing information, though these benefits only accrue with extended training with more trials. Overall, we have uncovered a conserved, stochastic coding scheme in vertebrates and invertebrates, and we identify a candidate mechanism, based on variability in a winner-take-all (WTA) inhibitory circuit, that improves discrimination with training.more » « less

Abstract BackgroundSituated cognition theory suggests that representations of concepts are products of the environment wherein we learn and apply concepts. This research builds on situated cognition by investigating how concepts are tangible to a professional engineering environment. Purpose/HypothesisThe tangibility of concepts in relation to social and material contexts was defined and explored in this study. Specifically, the conceptual representations of structural loads were examined within workplace and academic environments. Design/MethodA researcher conducted ethnographic fieldwork at a private engineering firm and in undergraduate engineering courses. Data sources from this fieldwork included the ethnographer's participant‐observation field notes, formal and informal interviews, and artifact documentation. ResultsFindings from this study described how academic representations of structural loads are more or less tangible to the social and material contexts of engineering practice. Representations documented in the workplace were found to be tangible to (1) real‐world conditions, (2) project/stakeholder constraints, and (3) engineering tools. Conversely, representations documented in the courses studied exhibited various degrees of tangibility to none, some, or all of these three traits. ConclusionsThese findings explicitly identify the ways in which representations of structural loads differ across academic and workplace environments and how these differences may contribute to the education–practice gap. Specific suggestions for making academic representations more tangible to workplace environments are provided based on findings from in the workplace, previous engineering education literature, and best practices observed in the courses studied. Future research considerations and the value of ethnographic methodology to situated cognition theory are also discussed.more » « less
