Geometric Reasoning Ability Based on Van Hiele Theory by Geogebra Software

Abstract

The difficulty of students in solving geometric reasoning problems which are based on Van Hiele’s levels is still low so that the right alternative solution is needed. For that reason, this research aims to answer those three main objectives. First, this study determines the difficulty experienced by the students. At second, this research identified the factors which cause the difficulty experienced by students in solving geometric reasoning problems based on van Hiele theory by GeoGebra software. At third, this research tried to determine the steps which are required to be taken to overcome the students’ difficulties in solving geometric reasoning problems based on van Hiele theory by GeoGebra software. The type of study is a descriptive study with a qualitative approach. The results showed that students’ geometrical reasoning ability was still in the low category; the causal factors are the students were rarely trained in geometric reasoning and lack of self-confidence. The step that should be done is by using van Hiele theory to detect the difficulty experienced by the students, including technology media such as GeoGebra software.
