“…(Van MerriëNboer, 2013: page 153) Some amount of research has been conducted to examine the effect of problem solvers' gender on problem solving (e.g. Balta, Mason & Singh, 2016;Duran, 2016;Gallagher, De Lisi, Holst, McGillicuddy-De Lisi, Morely & Cahalan, 2000;Sirait, Sutrisno, Balta & Mason, 2017). However, there is no clear evidence that either of the genders would be better in problem solving than the other, therefore, more research work is needed.…”
