Throughout the PBL process, what is noticed is that problem-solving and creative thinking skills of the students
are being developing. In PBL method, it is so important to make the students research with team spirit as if they are
the members of the same team. It’s not to be expected that the knowledge is given only by the teacher, but also the
students should give an effort to reach it (Sluijmans ve ark., 2001). With what is obtained in the process of PBL,
individuals become a good problem solver by using their thinking skills at the top-level.
Creative thinking, which is one of the ways of thinking given emphasis in mathematics education, is necessary for
the individual to be successful whenever he/she faces any kind of problem. In teaching-learning process, in order to
reach a creative mathematics teaching, it requires that the individuals, whose personal and social abilities are
specified, should express themselves efficiently, and be able to find the similarities or differences of the problems
they face, and carry out multi-faceted classification (Meissner, 2006).
