Abstract

This study aimed to examine the mathematical communication skills of female students in solving derivative problems in the eleventh grade at SMA Negeri 1 Sigi. The research followed a qualitative approach with a descriptive design. The study sample consisted of three female students selected based on a questionnaire focusing on feminine gender traits. Data were collected through written tests, interviews, and direct observation of the subjects. The dependability and credibility techniques were used to ensure the quality of the research findings. Data analysis involved three stages: data condensation, data presentation, and drawing conclusions. This study contributes to the existing literature by addressing the gap in understanding the mathematical communication skills of students with feminine gender traits, specifically in the context of solving derivative problems. The uniqueness of this study lies in the use of a feminine questionnaire for subject selection and the integration of mathematical language with everyday language and physical gestures in the evaluation of mathematical ideas. The findings revealed that female students with feminine gender traits demonstrated proficiency in all indicators of mathematical communication skills, including: (1) the ability to communicate their mathematical thoughts coherently and clearly to their peers and teachers; (2) effective use of mathematical language, such as numbers, letters, symbols, charts, graphs, and logical connections, in conjunction with everyday language and physical gestures when presenting, solving, and evaluating mathematical ideas during interactions with others; and (3) the capacity to explain mathematical ideas, situations, or relationships in written form. These results suggest that approaches combining mathematical language with physical interaction and everyday language can enhance the effectiveness of mathematical communication. The findings of this research can be utilized as a foundation for developing more inclusive and adaptive teaching strategies that consider gender differences in mathematics education.

Abstract

The purpose of this study was to describe the concept understanding ability of students in solving the problem of two-variable linear equation system. The method used is descriptive qualitative research. The subject of this research was 3 students taken from 26 students of class VIII SMPN 1 Balaesang. The results showed that the concept understanding of high mathematics ability students in restating concepts can restate concepts well using their own language, identify examples and non-examples and classify objects according to certain properties in accordance with the concept that can make mathematical modelling and determine equations and use the right solution steps according to the concept algorithmically. The concept understanding of medium ability students in restating concepts has been able to state concepts using their own sentences, identify examples and non-examples and are still lacking in classifying objects according to certain properties in accordance with the concept. The concept understanding of low ability students has not been able to achieve all indicators of concept understanding. Therefore, concept understanding is very important to be mastered by every student and the role of the teacher in facilitating the ability of each student.

The method used in this research is triangulation, data was collected through written tests and interviews. The results of this study showed that ST subjects were able to explain the third indicator given by the researcher. Subject SS could not explain the second indicator because the subject did not understand the cardinal directions so that it affected the third indicator, subject SS could not complete it. SR subjects could not explain the three indicators. In conclusion, students with high mathematical abilities can fulfill the indicators in restating concepts and presenting concepts in the form of mathematical representations (images), and some fulfill the indicators in using certain operating procedures in solving Pythagorean theorem problems. Students with moderate mathematical abilities only partially meet the indicators for restating and presenting concepts in the form of mathematical representations, but have not yet met the indicators for using certain operating procedures. Meanwhile, students with low mathematical abilities only partially fulfill the indicators in restating concepts, but do not meet the indicators in presenting concepts in the form of mathematical representations or in using certain operating procedures.
