“…The parametric Bézier curves widely used in computer graphics and for animation purpose, can also be constructed with the help of the input bar and slider of GeoGebra as shown in Figure 7. GeoGebra supplemented lessons enhanced students' motivation (Liu et al, 2011;Reis, 2010;Reis & Ozdemir, 2010;Vargas & Gamboa, 2013) and their mathematical reasoning and problem solving skills (Acuña, 2014;Akanmu, 2016;Albaladejo et al, 2015;Granberg & Olsson, 2015;Muzdalipah & Yulianto, 2015). Particularly, lessons on coordinate geometry (Khalil et al, 2018;Saha et al, 2010), on trigonometry (Rahman & Puteh, 2017;Zengin et al, 2012), in examining functions and their graphs (Takači et al, 2015), on statistics (Arbain & Shukor, 2015;Emaikwu et al, 2015), in understanding theorems related to circles (Bhagat & Chang, 2015;Praveen & Leong, 2013), fractions (Bulut et al, 2016), and on transformation geometry (Seloraji & Eu, 2017;Xistouri & Pitta-pantazi, 2013) improved students' academic result.…”
