STUDENTS’ CREATIVITY WITH INFORMAL DEDUCTION OF VAN HIELE’S GEOMETRIC THINKING LEVEL

Abstract

This paper aims to describe students’ creativity and geometric thinking informal deduction level in solving geometric problem which involves two students at informal deduction level in 10 grade. This can be reference to the other researchers or educators in developing students’ creativity in learning geometry. According to the research result, the two students at informal deduction level show different result. RS1 just can show fluency as creativity’s component in solving geometric problem. Besides, RS2 can show the all of creativity’s components in solving geometric problem. This shows us that even they are in a same level of geometric thinking, they also can be give different skill in solving geometric problems.

Keywords: Students’ Creativity, Geometric Problem, Geometric Thinking Level
