Geometry High School Students Thinking Ability Based on level van Hiele

Abstract

The purpose of this research is to obtain a description of the knowledge of high school students in solving mathematical problems seen from the ability to think geometry is based on van Hiele level. This study used a qualitative method with descriptive qualitative approach .. The results showed that: (1) the subject using geometric thinking skills, and (2) found a subject that there is a level between levels 1 and 2 on the van Hiele. The results of subsequent studies showed that knowledge of a subject that is at the level between 1 and 2 at the level of the van Hiele in thinking geometry to resolve the issue as follows: (1) at the initial stage of the subject using drawing techniques, (2) and the subject to identify and explain the geometry drawn, (3) the subject can further explain the definition of a wake-drawn, (4) the subject of finding answers requested of the matter.
