“…Encouraging learners to pursue multiple solutions to mathematical problems can improve their effectiveness and flexibility in solving such problems (Daher, Tabaja-Kidan, & Gierdien, 2017;Levav-Waynberg & Leikin, 2012a, 2012bStanislaw & Krug, 2014) even though it does not always affect their performance in mathematics (Schindler et al, 2018;Schukajlow, Krug, & Rakoczy, 2015). Furthermore, utilising MSTs allows more potentially creative learners to present their creative solutions to problems (Levav-Waynberg & Leikin, 2012a;Sriraman & Dickman, 2017). Deductive reasoning and critical thinking skills are important in geometry problem-solving and in the 21st century, and the use of MSTs can improve these skills (Segal, Stupel, & Flores, 2017;Sriraman & Dickman, 2017).…”
