Student’s semiotics in solving problems geometric diagram viewed from peirce perspective

In mathematics, semiotics is a critical element in understanding and constructing meaning, not least in understanding and solving mathematical problems. Everything associated with signs, symbols and relations between symbols is called semiotics. The geometry diagram is one of the mathematical topics that contain the semiotic structure of the visual features of an object. This feature is represented to convey the meaning of the intended object. This research is a descriptive qualitative approach, by collecting data through tests (problems) and interviews. The study aimed to describe the semiotic process of students in solving problems related to the construction process of meaning in the geometry diagram based on the sign relationships, from the perspective of Charles Sanders Peirce. The results indicate that the formation of meaning and understanding of students about the representation of geometry diagrams depends on the structure of the geometry diagram. in addition, the relationship between each semiotic component is presented.
