MATHEMATICAL COMMUNICATION: A SURVEY OF MATHEMATICAL CONCEPTS IN GEOMETRY PROBLEMS IN RIAU PROVINCE PUBLIC MIDDLE SCHOOL
One of the main goals in learning mathematics is to produce students who have a complete understanding of the mathematical concepts they are learning. This paper is the result of an initial study of a research that will be carried out in depth on this matter, which aims to explore oral and written mathematical communication skills in geometry problems in junior high schools in Riau Province. This research is an exploratory research with an ethnographic approach. The data collection techniques used were observation, interviews and literature study. The results of the research show that: 1) Mathematical communication skills students on flat wake material, in general it is said to be moderate. Because most students have not been able to fulfill all indicators; 2) Students with high mathematical abilities are able to achieve almost all indicators of mathematical communication skills; 3) Students with moderate mathematical ability do not master several indicators of mathematical communication ability; and 4) Students with low mathematical abilities have not been able to master the indicators of mathematical communication skills.
