According to Babadoğan (2000), if the learning styles of students are known,
the manner of learning of individuals and what type of teaching design
applications are required can be understood in an easier manner. Thus, the
teacher will be able to form teaching settings primarily suitable for him/herself
and then the student. There are many studies demonstrating the effect of matching
teaching styles with learning styles on the achievement of the student [5]. The
most numerous of these studies in the literature are studies covering the 4MAT
teaching model [6]. When the TIMSS-1999 reports are examined, it can be
observed that Turkey’s achievement in mathematics is much lower than the
international average. The problems in the manner of perceiving mathematics is
indicated to be among the reasons for such a result [7]. The problems in the
perception and processing of mathematical concepts by students, lead to the low
level in mathematical achievement. Due to the existence of problems in the
perception and processing of information by students in the mathematics lesson
and the inclusion of the dimensions of the perception and processing of
information in McCarthy’s learning style model, the effect of teaching based on
the 4MAT teaching model developed by McCarthy on the achievement of
students was analyzed in this study.
