“…Examples range from dash‐wedge diagrams, which illustrate atomic‐scale spatial configurations, to geologic block diagrams, which illustrate geologic structures at scales ranging from centimeters to tens of kilometers. While these types of representations are ubiquitous in STEM learning (Ainsworth, Prain, & Tytler, ; Cromley et al., ; Hegarty, ; Newcombe & Stieff, ), students struggle to interpret the 3D spatial relations conveyed in these diagrams (Kali & Orion, ; Rapp, Culpepper, Kirkby, & Morin, ; Stull, Hegarty, Dixon, & Stieff, ). A failure to understand these representations can be a barrier to success in STEM, as a key aspect of scientific practice is both understanding and self‐generating these types of representations (Ainsworth et al., ; Nersessian, ).…”
