Geometric thinking level of the Indonesian seventh grade students of junior high school

Abstract

Enhancement of students' ability to think geometry at level 0 until level 4 will configurate the comprehensive geometric knowledge. The aim of this study was to analyze the geometric thinking level of seventh grade students of junior high school. This research is part of a series of research conducted for 2 years with the Design Didactical Research (DDR) method. The geometric thinking ability test was given to 32 students in the VIIA class. The questions used are 25 questions which contain 5 levels of thinking geometry proposed by Van Hiele. The visualization ability data of the visualization level ability test held by students was obtained by 32% of students in pre level 0, 47% of students in level 0 and 21% of students at level 1. While at level 2, 3, 4 there were no students who arrived to that level.
