Representasi Matematis Siswa Bina Prestasi MTsN 1 Jember dalam Menyelesaikan Masalah Segiempat Ditinjau dari Level van Hiele

Abstract

This study aims to determine mathematical representation of Students’ Ability in Solving Quadrilateral Problems Based on Van Hiele’s Levels at an Enrichment Program in MTsN 1 Jember.. This research is a descriptive qualitative research. The subjects of this study were 17 students of class IXA at ​​MTsN 1 Jember. The data collection method on this research are using test and interview methods. The test instrument on this research were a test of ability to think geometry and a test of mathematical representation on rectangular material. The results of data analysis were carried out by comparing the results of the mathematical representation test with interviews, then categorized based on Van Hiele's level of thinking from the results of the geometric thinking ability test. The results showed that students with a visual thinking level had a tendency to use symbolic and verbal representations in solving problems. Students with the analytical thinking level tend to use verbal, visual, and symbolic representations in solving problems.
