“…Research on cognitive obstacles related to fraction sense assignments is crucial, because it aids in understanding how these obstacles can be minimised. Meanwhile, most of the previous decade's research on preservice mathematics teachers related to fraction sense tests studied the fraction sense strategy used, the preservice teachers' low performance in the fraction domain, their understanding of representation and computation skills, their reasoning of fraction amounts, and their mental calculation (Courtney- Clarke & Wessels, 2014;Lemonidis, Tsakiridou, & Meliopoulou, 2018;Şengül, 2013;Son & Lee, 2016;Whitacre & Nickerson, 2016;Yang, Reys, & Reys, 2009). Consequently, a set of information is further required to acknowledge preservice teachers' cognitive obstacles on fraction sense tests.…”
