Representasi Matematis Siswa dalam Menyelesaikan Masalah Sistem Persamaan Linear Ditinjau dari Gaya Kognitif Reflektif-Implusif

Abstract

The purpose of this study is to describe the mathematical representation of students with reflective cognitive style in solving linear equation system problems and to describe the mathematical representation of students with impulsive cognitive style in solving linear equation system problems. Researchers set four research subjects from the results of the reflective-impulsive cognitive style test consisting of two subjects with reflective cognitive style and two with impulsive cognitive style. The researcher conducted tests on the system of linear equations and interviewed the four subjects. The type of research used is a case study with a qualitative approach. Data analysis techniques are data reduction, presentation, and conclusions. The results showed that students with reflective cognitive styles could solve linear equation system problems using visual and symbolic representations, and students with reflective cognitive styles could use verbal representations but were still not precise. while students with impulsive cognitive style are able to solve linear equation system problems using verbal representations.
