Education of mathematics includes studies in the process of learning and teaching mathematics. All the
activities in that process depend on the acquisition of mental skills (Hatfield, Edwards & Bitter, 1997). Most of
the mathematical concepts are abstract requiring high levels of cognitive activity. In the traditional classroom
environment, the subject to be learnt is not individualized and the attention of the students is not drawn to the
subject. It should be admitted that more concrete and less abstract concepts are learnt more easily (Baki, 2002).
Furthermore, Ersoy (1997) remarks that individuals have some problems with their forms of perceiving
mathematics. The fact that the students have problems with perceiving mathematical concepts and operating
them brings about a low level of success in mathematics. Consequently, the implementation of theories
dependent on cognitive basis in mathematics courses is considered to be more effective than the traditional
method.
