Students' understanding of system of linear equations through mathematical modeling

Abstract

This study aims to develop a learning trajectory of students' understanding of system of linear equations in three variables using mathematical modelling. This study was conducted in SMA Negeri 4 Palembang participated by 6 tenth grade students in pilot experiment and 30 tenth grade students in teaching experiment. The results show that the mathematical modelling based activities can help students build mathematical models as system of linear equations in three variables and solve the system using modelling steps.
