Visualisasi dan Nalar Intuitif dalam Matematika

Abstract

Solving problems skill is the heart of mathematics, while visualization is the core of solving the mathematical problem. Visualization is the ability to see and under- stand the situation of the problem. In a mathematical calculation process, someone will often use the symbols, visualization diagrams and other forms of mental pro- cess involving the existed imagination while working on it. It can certainly explain that visualization can help intuitive reasoning. This study is a quasi-experimental research and conducted in SMA Swasta Persiapan Stabat which aims at determin- ing whether the visualization in mathematics learning can improve the students' intuitive reasoning. Visualization tools used in this research is Geogebra computer program. The study was conducted on the geometry subject given to the tenth grade students.
