Students’ Understanding of Geometry: Points and Line

Abstract

The aim of this study is to find out kind of mistakes that students make in geometry, especially in points and line materials. The research subjects are the Geometry class students at Mathematics Education Study Program, University of Timor. This research is a qualitative descriptive study. The data collection techniques used are observation, tests, and interviews. Based on the results of the study, it was found that Students still make mistakes in solving geometry problems due to their low understanding in points and lines material. As for what causes this to happen is the inability of students to understand the concept and even ignorance of students regarding the material.
