Analysis of Students' Mathematical Representations in Solving Geometric Problems

The objective of this present research is to describe students' mathematical representations in solving geometric problems. A qualitative approach was adopted, and the subject was 6 Students Grade IX, MTs Muhammadiyah 1 Malang, Indonesia. The subject consisted of 3 female and 3 male students. The data were collected through tests, interviews, and document analysis. The research results showed that: 1) the representation forms mostly used by the students were varied, among others are description ad pictures; 2) most students solved the problems using picture first to facilitate their work, but some of them used representations of written expressions, symbols, and conjectures, and, 3) students' fluency and flexibility in constructing the representations may be called to be good enough, and then after interviews, students could represent their mathematical ideas completely either in pictures or written form to solve problems dealing with geometric materials.
