Mathematical communication skill of senior high school students based on their personality types

Abstract

Every student with different type of personality, extrovert or introvert, has his or her own characteristic. The difference of the personality type can influence their way of having confident attitude, communication, and other activities including learning. This research aims at analysing student's ability of mathematical communication with extrovert and introvert personality type. This research is descriptive qualitative research. The data of this research was obtained from 34 students of senior high school in Sukoharjo region with heterogeneous abilities, collected using written test and interview. The result of the research gave an overview that mathematical communication skill of students having introvert personality can arrange conjecture, make an argument, and formulate generalization definition. However, they had difficulty in understanding a mathematical presentation. Meanwhile, the students having extrovert personality can explore their ideas, but they have difficulty in revealing the idea or mathematical paragraph in their language. In order to improve mathematical communication, students should be given mathematical problem related to mathematical communication and the teacher is expected to know the characteristics of the students so that the teacher can provide appropriate actions.
