Students’ Mathematical Communication Ability in Solving Trigonometric Problems

Abstract

Abstract Mathematical communication ability is a person’s ability to convey mathematical ideas orally or in writing which are presented in the form of graphs, tables, diagrams, symbols, or mathematical models. The purpose of this study is to determine and describe the level of mathematical communication ability of students. This type of research is a qualitative descriptive study. The sampling technique was using a purposive sampling technique. The results showed that the percentage of students’ mathematical communication ability in the text writing indicator, 38% of students were in the poor category, 50% of students were in the moderate category, 11% of students were in a good category, and 4% of students were in the very good category. On the drawing indicator, 7% of students were in the poor category, 57% of students were in a low category, and 36% of students were in the moderate category. 14% of students were in the poor category, 50% of students were in a low category, 18% of students were in the moderate category, 11% of students were in a good category, and 7% of students were in the very good category.
