“…The result of study, significant differecence were found between groups' academic performances in favor of experimental group. In the literature, there are studies,regarding traditional instruction is not enou gh and GeoGebra-assisted instruction is positive impact on the learning process (Dikovic, 2009;Shadaan & Leong, 2013) increases the level of academic performance (Saha, Ayub & Tarmizi, 2010;Gómez-Chacón & Escribano, 2011;Zengin, Furkan & Kutluca, 2012;Güven & Yılmaz, 2012;Tatar, Kağızmanlı & Akkaya, 2014;Kan, 2014;Aydos,2015;Acar, 2015;Bhagat & Chang, 2015;Ünlütürk-Akçakın, 2016;Kepçeoğlu & Yavuz, 2017;Ocal, 2017;Çekmez & Baki, 2018) and makes learning easier (Taş, 2010;Reis & Özdemir, 2010). In this study, significant differecence were found between groups' geometric and ovarall performances in favor of experimental group however there is no significant difference between the experimental and control groups with respect to algebraic performance.…”
