KEMAMPUAN KOMUNIKASI MATEMATIS MAHASISWA DALAM PEMECAHAN MASALAH KALKULUS II

Abstract

Mathematical communication has an important role in mathematics learning for
instance, sharpening the way of thinking, improving students’ ability in observing the
relevance of various mathematics concept, measuring the development of
mathematics understanding, and reflecting students’mathematics comprehension.
For these reasons, it is crucial to know how far students’mathematical
communiation skills. Therefore, this study aims to describe mathematical
communication skills of majors students STKIP MPL. Mathematical communication
skills are seen through students’answer analysis in solving Calculus II problem. The
research subject consists of three students who get score A, B, dan C. Based on the
analysis result found that mathematical communication skills of these subjects are
able to communicate mathematical ideas by using pictures and Mathematics
symbols. However, they have differences ability in describing and analysing. The first
subject is able to describe and analyze pictures precisely. The second subject is not
able to describe pictures well, thus the pictures are difficult to understand. While the
third subject is able to describe pictures well but can not analyze the picture so the
problem solving method is not appropriate.

Keywords : mathematical communication skills, problem solving of Calculus II
