Description of Senior High School Students' Mathematical Problem-Solving Abilities in Systems of Linear Equations in Three Variables Based on Keirsey Personality Type

Abstract

This research aims to describe students' mathematical problem-solving abilities in Systems of Linear Equations in Three Variables based on David Keirsey's four personality types: Guardian, Artisan, Rational, and Idealist. This research used the qualitative method with a descriptive approach with subjects involving 4 students of grade X of Senior High School Muhammadiyah 1 Unismuh Makassar, who represented each type of Keirsey's personality. The selected students have carried out two types of tests, namely the Keirsey Temperament Sorter and the Mathematics Ability Test, with the material of three variable linear equation systems. The research results show that rational student has been able to pass all the indicators of the problem-solving stages according to Polya's theory, namely understanding the problems, making plans, solving the problems, and re-examining them properly. Guardian student has been able to pass all the indicators but has not been maximized at solving the problem. Artisan student has been able to go through all stages but sometimes rush to solve problems. Also, an idealist student has not been able to pass all the indicators of the stages of the problem-solving well.Neneng Anastasyia^1*,
