Abstract

Learning in the 21st century can be defined as learning that provides 21st century skills, one of which is communication. Mathematics learning allows students to communicate mathematical ideas clearly. Different personality types can affect the way they communicate, and other activities in learning mathematics. This study aims to describe students' mathematical communication skills in terms of Keirsey personality types, namely Idealist and gender who have Idealist personalities. Descriptive qualitative research was used in this research and was carried out at Junior High School Negeri 1 Purwodadi in the 2019/2020 school year. The research was conducted on the subject of class VIII I with idealist personality type, then selected 1 female student and 1 male student using purposive sampling. The researcher is the main research instrument with the help of observation guidelines, questionnaires, tests of mathematical communication skills and then interviews. The data collection technique is a triangulation technique by comparing the answers to the mathematical communication skills test and interviews. Data reduction, data presentation and drawing conclusions are data analysis techniques used in this study. Female students with idealist personality types communicate better mathematically than male students with idealist personality types as shown in the results of this study.

Abstract

Mathematical communication is an important skill that must be developed in trigonometry learning but is often not developed optimally. Students tend to rely on procedural formulas without being able to explain, represent, and systematically justify their reasons.  Habits of mind are one of the internal factors indicated to influence students' mathematical communication skills. The purpose of the study to describe students’ mathematical communication skills in trigonometry based on habits of mind. This research uses descriptive approach and qualitative data collection techniques such as mathematical communication skill test and in-depth interviews. The subjects of the study were 22 students of class X E3 at MA Negeri Sukoharjo selected purposively based on their habits of mind categories which are limited, developer and expert, from the results of using the Habits of Mind questionnaire. The result showed that: (1) student with the limited habits of mind category had weak mathematical communication skills in all indicators namely drawing, mathematical expression, and writing; (2) student with the developer habits of mind category showed better mathematical communication skills, but still showed inconsistencies and incompleteness in written representations and narratives; (3) Student in the expert category have excellent mathematical communication skills across all indicators, can communicate mathematical ideas completely, accurately, and systematically. The findings of this study indicate that habits of mind have an important role in developing students’ mathematical communication skills in trigonometry topic. Therefore, teachers are encouraged to design learning activities that encourage habits of mind to improve students' ability to communicate mathematical ideas effectively.
