Analysis of Garde IX Student’s Mathematical Understanding Ability on Quadratic Equation Material

Abstract

This study aims to describe the mathematical understanding ability of grade IX students in the quadratic equation material. This research method uses a qualitative descriptive research type. The subjects in this study were grade IX students of the Syahrani Bariah Zulkarnanen Islamic Boarding School with a sample size of 5 students. The data collection technique used a test technique in the form of essay questions totaling 4 questions and each question representing each indicator of mathematical understanding ability. The results of the study showed that the mathematical understanding ability in indicators 1) students are less able to restate the concepts that have been learned, 2) students are less able to identify examples not from examples, 3) students are able to change the form of representation into other forms of representation, 4) students are able to develop the concept of quadratic equation material. So the students' mathematical understanding ability in understanding the problem, planning the solution, and rechecking all the steps that have been done is classified as moderate.
