- This research is qualitative research with a descriptive, explorative approach. That aim is to describe the ability of students' mathematical representation in solving geometry problems. The population was all Mathematics Education Study Program who programmed the Basic Geometry Course. The sampling techniques were Stratified Sampling and Purposive Sampling. The instruments were an initial test to categorize the students’ problem-solving skill into three categories (high, medium, and low), a diagnostic test to get the external representation data, and interview guidelines to obtain the internal representation data. The instruments were valid and reliable. This study also conducted triangulation techniques to test the validity of the data. The results show that: Firstly, the high-ability students in solving geometry problem tended to present the visual representation appropriately, to write mathematical expressions inappropriate symbols, and to employ verbal representation at each stage in solving the problem. Secondly, the middle-ability students presented visual representations but less representative, used mathematical expressions but lack verbal representations. Finally, low-ability students in solving the geometry problem did not present appropriate visual representations, use little mathematical expression and limited verbal representations.
