Kecemasan Geometri Siswa dalam Menyelesaikan Masalah Bangun Ruang Sisi Datar Ditinjau dari Teori Van Hiele

Abstract

Geometry anxiety is anxiety that arises when dealing with things related to geometry. Geometry anxiety levels start at low, medium, high, and panic. The purpose of this research was to describe student’s geometric anxiety in solving the problem of flat-sided shapes in terms of van Hiele's theory. This type of research is a qualitative descriptive study. The subjects of this research were two students each at the level of visualization, analysis, and informal deduction. The data collection technique is done through a combination (triangulation). The results of this study indicate that students of each level have different geometric anxiety. Visualization students have medium and high anxiety in defining and identifying the properties and elements of flat-sided shapes. Analysis students have medium anxiety in solving geometry problems related to the calculation of diagonals, volume, and surface area. Informal deduction students have high anxiety in solving problems related to the definition and elements of building space and problems in the form of stories
