Mathematical connection: How is student's ability to complete a two-variable linear equation system?

Abstract

The aim of this study is to describe how students make mathematical connections in two-variable linear equation system. This study using three indicators to determine the ability of student's mathematical connections, there is ability connection between concepts in mathematics, procedures are used by students to solving problems, and ability students to solving contextual problems. Test and interview were used to collect data on ninth-grade students at SMP Negeri 3 Singosari, one of the public junior high schools in Malang, East Java, Indonesia. Based on the test result, the average student's mathematical connection ability is 76.37 which are in good category. The students' ability to connect between concepts that arise in solving systems of two-variable linear equations uses substitution and elimination using appropriate substitution algorithm or elimination procedures.
