“…Similarly, there are also studies which compared primary school mathematics curriculums (Bal-İncebacak, 2022;Çoban & Aşçı, 2022;Koç, 2019) and secondary school mathematics curriculums (Güzel, Karataş, & Çetinkaya, 2010;Öztürk & Diker-Coşkun, 2022) in Türkiye with the curriculums of other countries. Besides, some of the studies compared the current and past mathematics curriculums in Türkiye at the elementary level (Albayrak, 2017;Baş, 2017;Gökbulut & Aslan, 2017;Özmantar & Öztürk, 2016), secondary level (Beyendi, 2018;İlhan & Aslaner, 2019;Özmantar, Akkoç, Kuşdemir-Kayıran, & Özyurt, 2018;Şen, 2017), and high-school level (Çiğdem, 2022;Özşentürk-Balçın, 2021;Yazıcılar & Bümen, 2017). Furthermore, some of the studies examined elementary mathematics curriculums (Işık & Kar, 2012), secondary mathematics curriculums (Tekalmaz, 2019), and secondary geometry curriculums (Cansız-Aktaş, 2013) in the light of teachers' opinions.…”
