“…It has been expressed in many studies that dynamic geometry software (DGS) provides students opportunities to establish connections between mathematical objects and graphical representations (Öçal, 2017; Shadaan & Leong, 2013; Taş, 2016) and supports the active construction of mathematics knowledge within a dynamic learning environment (Dayi, 2015; Hohenwarter & Fuchs, 2004; Hutkemri & Zakaria, 2014) and enables conceptual learning with the aid of animation and visual materials (Diković, 2009; Tatar & Zengin, 2016). Moreover, it has shown in the results of some studies that using DGS has positively increases students' mathematics/geometry achievement (Chan & Leung, 2014; Erbaş & Yenmez, 2011; Günhan & Açan, 2016; Köklü & Topçu, 2012; Özmen, 2019; Pilli & Aksu, 2013; Topuz, 2017; Turk & Akyuz, 2016) and conceptual learning (Caglayan, 2014; Hutkemri & Zakaria, 2012, 2014; Zengin, 2018). However, only a few studies (Delice & Karaaslan, 2015; Doktoroğlu, 2013; Işıksal & Aşkar, 2005; Önür, 2008) focus on the effect of educational software on linear functions and graphs related to students' mathematics achievement for seventh‐grade and high school students but not for eighth graders.…”
