Some of the theories relying on cognitive basis depend on the individual differences and learning styles of
the students. Since the 1940s, many models of learning styles have been defined. Some of those are the
domain-dependent domain-independent styles, Gregorc model of learning style, Dunn model of learning style,
Kolb model of learning style, and 4MAT. Each of these models of learning styles emphasizes one of several
different dimensions, namely, cognitive, affective, and physiological (Cornet, 1983). The cognitive dimension
emphasizing the perception and operation of knowledge has a crucial importance for teaching mathematics
(Basıbüyük, 2004). According to Babadogan (2000), if the learning styles of the individuals are determined, how
the individuals learn and what kind of teaching design should be implemented for them can be grasped more
easily. Thus, according to these styles, the teacher can organize appropriate teaching environments for both
himself and the students. There are many studies demonstrating that matching the teaching styles with the
learning styles has proved to be influential in student success (Scales, 2000). Therefore, we think that the
teaching models depending on cognitive dimension and learning styles will be successful in teaching
mathematics. In this study, the influences of geometry teaching implemented depending on the 4MAT teaching
model were examined as the students have some problems with perception and operation of knowledge in
mathematics courses .Both perception and operation of knowledge constitute the foundation of McCarthy’s
model of learning style.
