“…In fact, the impact of problem posing-based mathematics teaching on learning outcomes were investigated by a variety of studies (Akay & Boz, 2009;Cankoy & Darbaz, 2010;Güzel & Biber, 2019;Chen et al, 2015;Guvercin & Verbovskiy, 2014;Turhan & Güven, 2014). Previous research has indicated that the utilize of problem posing-based approaches in education facilitates learning of mathematical concepts (Drake & Barlow, 2008;Van Harpen & Presmeg, 2013), increased critical thinking skills (Lowrie, 2002;Singer & Voica, 2012), developed cognition and metacognition like high-level thinking skills (Rosenshine et al, 1996), offered opportunities for problem solving (El Sayed, 2002), ensured development of problem posing skills (Chen et al, 2015;English, 1997;Suarsana et al, 2019) and contributed to development of positive attitudes and beliefs related to mathematics (Akay & Boz, 2010;Barlow & Cates, 2006;Chin et al, 2002;Sanchez-Elez et al, 2014;Turhan & Güven, 2014). Indeed, problem posing becomes more important than problem solving.…”
