Profile of students' mathematical representation ability in solving geometry problems

Abstract

Mathematical representation is students' ability in expressing mathematical ideas in the form of drawings, mathematical equations, and words/written text. Mathematical representation is needed in solving mathematical problems. This research aims to find out the profile of students' mathematical representation in solving geometry problems. The research method uses descriptive with subjects of 33 students of class VIII Junior High School Muhammadiyah 1 Surakarta. Data is collected by a mathematical representation test. Data analysis show that there are 21.21% of students with high representation ability, 33.33% students with moderate representation ability, and 45.46% of students with low representation ability. Based on the results, it is known that most of the students still have low mathematical representation ability. Students find it difficult to understand problems and write equations correctly. This is because students are not used to solving problems in the form of visual, verbal, and symbolic representations. Therefore, the teacher must train the students' mathematical representation skills by applying multiple representation learning models.
