“…In fact, within mathematics' education research community it is consensual that the narrow ability of Visualization is relevant to all areas of Mathematics and particularly to Geometry (Sinclair et al, 2016;Yildiz & Özdemir, 2017), being itself an object of prolific research often under the names of visuospatial reasoning, visualizing, spatial reasoning, spatial thinking and visual reasoning (Sinclair et al, 2016). Spatial skills are associated with success in science, technology, engineering, and mathematics domains (Gilligan, Flouri, & Farran, 2017;Julià & Antolì, 2017;Kell & Lubinski, 2013). Even tough, as formulated by Bishop (2008), spatial abilities may constitute "an area like language, which is every teacher's responsibility" (p.79), Geometry Education's field produces fertile ground to, in natural contexts, see and learn about spatial reasoning in curricular motion (Sinclair et al, 2016), for it plays an important role in the process of interpreting visual information related to learning geometry (Kösa, 2016).…”
