Learning Mathematical Modeling: The 7th Grade-Students Skills in Solving Inverse Proportion Visual-Formed Problem

Abstract

This research aims to determine the 7 grade-students skills in solving the inverse proportion visual-formed problem through mathematical modeling learning. This research type was descriptive research using a qualitative approach. The subjects of this research were 19 students of the 7 grade-student of SMP Negeri 6 Indralaya Utara. We carried out the data collection techniques through the post-test and interviews. Based on the findings, here were found that the mathematical modeling problem in terms of visual provided a significant contribution to the student skills in solving the inverse proportion visual-formed problem. The details of the occurrence percentage of indicators were as follows: the identifying problem was 42,98%, the defining variable was 28,07%, formulating a mathematical model was 45,61%, completing the mathematics model was 52,63%, and applying the model was 50,00%.
