Abstract


This study aimed to analyze the students’ mathematical representation ability viewed from
spatial cognitive style on geometry. This study used qualitative method. Subjects in this study
were students X,MIPA 1 SMA Muhammadiyah 1 Purbalingga. The sampling technique of this
study was GEFT (Group Embedded Figure Test) by taking three students for a group of high
spatial cognitive sytle, 3 students for a group of medium spatial cognitive sytle, and 3 students
for a group of low spatial cognitive sytle. Data analysis techniques used in this study were
reduction of data (data reduction), description of data (data display) and conclusion
(verification). Data collection techniques in this study were tests, interviews, and
documentation. The results of this study indicate that high spatial cognitive style group is able
to master three indicators of representation, those are: recording and communicating
mathematical ideas in the from of symbol or picture on geometry using the words/ written text
in solving geometry problems as well as creating mathematical model from the ideas by
applying mathematical expressions in solving geometry problems. While medium spatial
cognitive style group is able to master two indicators, those are: recording and
communicating mathematical ideas in the from of geometry symbol/image and written words
written texts in solving geometry problems. In addition, the low spatial cognitive style group
is able to master an indicator that is recording and communicating mathematical ideas in the
from of geometry symbol or picture.

Keywords: Mathematical Representation Ability, Spatial Cognitive Style
