Abstract

This article aims to analyze students mathematical communication skills in three-dimensional material. The research was conducted with a qualitative approach with a case study method. The subjects of this study were five high school students majoring in Science. Data on students mathematical communication skills useed tests and interviews. The results showed that students mathematical communication verbally was good at explaining answers clearly and systematically from written answers, but students written mathematical communication was still lacking in describing problem situations and stating problem solutions using images and presenting algebraic solutions correctly and explain ideas, situations and mathematical relations in writing.
