Thinking Levels Analysis of Flat Up Geometry Based on Van Hiele’s Theory on Students in Fifth Grade

Abstract

The purpose of this study was to analyze/describe the level of geometric thinking of fifth grade students based on Van Hiele's theory. The research method used in this research is descriptive qualitative. The subjects of this study were 20 students of class VA MI MPI Cendono who were grouped based on high, medium, and low ability groups. The data analysis technique used is based on Miles Huberman's theory through data reduction activities, data presentation, and conclusions or verification. The results showed that the students of class VA MI MPI Cendono had different levels of Van Hiele geometric thinking. The level of Van Hiele geometric thinking in the high ability group students is averaged at level 2 of informal deduction, while students in the medium and low ability groups averaged at level 1 of the analysis.
