Extended reality (XR), which includes augmented and virtual reality, is not new to the classroom, but it is increasingly feasible for a wider number of educators (Pellas et al, 2021; Kaser et al, 2019). This uptake is attributable to a combination of decreased hardware costs, increased performance and expanded software libraries. Importantly, these visualization platforms have profound implications for teaching and learning by providing the means to present physically inaccessible (i.e. distant, fragile, micro/ macroscopic, dangerous, etc.) content in context, at human scale and in a way that's responsive to a wide range of body-centered interactions and familiar representational characteristics (Bowman and McMahan, 2007; Kersten-Pertel et al, 2013;Whitlock et al.,2020).
