“…Some researchers agree on the usefulness of modeling in mathematical teaching. Their investigations show that students struggle to solve problems and to apply concepts to other disciplines, when they have studied them only from a theoretical point of view (Lesh & Doerr, 2003;Kwon, 2002;Blum, 2009;Haines, 2009;Bas, Cetinkaya, & Kursat, 2009). According to these studies, modeling motivates students to get involved in mathematic courses and to raise their interest in learning new concepts.…”
