“…However, it was observed that mathematics and geometry achievements were very low in international exams such as PISA and TIMMS and in national exams such as LKS and YKS. Literature review revealed that teachers did not prioritize geometry instruction in Turkey, students' geometry achievement levels were related to the geometry achievement levels of teachers, the knowledge they acquired in undergraduate programs on the concept of visual literacy and their professional experiences was not sufficient to conduct visual literacy applications in their classes, and the geometrical thinking levels of pre-service teachers attending faculties of education were lower than expected (Chen, Dipinto, & Newman, 2017;Durmuş, Toluk-Ucar, & Olkun, 2002;Erdogan, 2006;İlhan, 2015;Özdemir, Duran, & Kaplan, 2015;Paksu, 2013;Şahin, 2008). Together with that, literature review demonstrated that the reasoning skills of the students , teachers or pre-service teachers on geometric shapes were low, they did not have sufficient knowledge on visual mathematics literacy perception, there was a significant correlation between mathematical thinking skills of the teachers and mathematics literacy performance of the students, there was a significant correlation between visual mathematics literacy perception and problem solving skills, and the teachers lacked geometry content knowledge or it was important to measure their geometry performance levels (Amsterlaw, 2004;Baki, 2001;Bekdemir & Duran, 2012;Çalışkan, 2016;Gallant, 2009;Hohenwarter & Preiner, 2007;Jadallah, 2009;Oaksford, 2005;Şahin, 2005).…”
