Analysis of students mathematical communication ability

[摘要] This study aims to (1) analyse and describe the difficulties by students in solving problems of mathematical communication test in circle material; (2) analyse the factors that causing the students have difficulty in solving mathematical problems in circle material. The type of research in this study is qualitative descriptive. The data collected in the form of writing, words, and pictures. The research was conducted at SMA Negeri 1 Tualang, Riau. The subjects in this study are 36 students of class XII. Data collected methods used in this study is a test mathematical communication ability indicator in circle material. Based on the research which are found three factors that cause students difficulties in solving problems include: (1) students have not been able to understand the concept of the problem and students have not been able to interpret the sentence about the presented questions; (2) students are less precise in performing calculations on algebraic form operations such as subtraction, multiplication, and division and while working on students in a hurry; (3) students not yet understand the concept of drawing circles from known elements or otherwise resolving questions from the presented images.
