Learning Design of Two-Variable Linear Equation System using Buying Context

Abstract

This study aims to design a system of two-variable linear equation learning in class VII SMP using the PMRI approach. This research is a type of design research with a type of validation study. The results of this study are that buying and selling transactions can be used as a Realistic Context in learning mathematics, especially as an effort to develop students' understanding of the concept of system of two-variable linear equation learning. Because through the learning path that has been compiled using the context of buying and selling students can find and express their own ideas on how to solve problems about system of two-variable linear equation learning.
