“…Our particular interest lies in research related to teacher training in visualization and spatial reasoning (VSR), specifically in pre-service teachers. Several studies have addressed problems of this group as representation of three-dimensional objects (Gaulin, 1985;Malara, 1998), acquisition of basic concepts of geometry (Hershkowitz, 1989;Tatsis & Moutsios-Rentzos, 2013), concept of symmetry (Son, 2006), identification and classification of solids (Guillén, 2005), development of three-dimensional solids (Cohen, 2003), or problem-solving strategies in relation to levels of spatial ability (Buckley, Seery, & Canty, 2019). Other studies have focused on the mathematical specialized knowledge (Hill, Ball, & Schilling, 2008) on the specific content of visualization (Godino, Gonzato, Contreras, Estepa, & Díaz-Batanero, 2016;Gonzato, 2014;Miragliotta & Baccaglini-Frank, 2017).…”
