Abstract

Instruments are tool that used to collect research data. The instrument consists of two types, namely the main and supporting instruments. In this paper, we develop the supporting instruments which are used in qualitative research such as commognitive perspective. The instrument development aims to explore and reveal students' cognition in understanding derivative tasks that are valid and reliable. It means the instrument is needed in order to explore cognition and communication in an inseparable manner according to the theory used in this research. The two supporting instruments that developed in this study are the mathematical ability test (MAT) and the derivatives understanding task (TMT). Moreover, the developed MAT instrument is accompanied by source questions, grids and indicators. The MAT consists of 10 questions, and this was tested empirically in the category of valid and high reliability. Furthermore, TMT is developed as a reference for exploring student commognition. The TMT consists of 14 questions. The preparation and development of the instruments in this study are based on relevant theories and supported by empirical data. At the expert review step, validation is carried out in terms of content, construct and language by experts. Each step is tested for readability, then suggestions and comments are provided for improvement. The final results obtained show that the two supporting instruments (MAT and TMT) are feasible to use in exploring student commognition because these bring up keywords, visual mediators, endorsed narratives, and routines, as a commognition characterher.

Abstract

Media is one of the components in learning that has a function as a means of non-verbal communication. In designing instructional media, a teacher needs to adapt to the students need. As a result, it can be effective and efficient. Students as learning centers are expected to develop and have better communication skills, so that they can participate actively, be able to analyze and be able to solve their own problems. Learning media that attracts students' interest will create creativity and innovation to themself which is in line with the challenges of the twenty-first century. On the other hand, the mindset that can bring out the creative potential in everyone is Design Thinking. In this research, we use a theoretical perspective from design thinking with activities that consist of 5 stages, namely empathize, define, ideate, prototype, and test. We conducted in-depth observations and interviews to identify problems in students of class X-4 at the Madani Integrated Model Senior High School. The sample used was 4 students. The sample selection was based on the extreme right and left extreme sample criteria. The findings in the interview formed an "empathy map" which then formulated insights and formed a design challenge. The result is a poster in Biology learning on growth and development material. The posters that have been made have gone through a series of trials. Furthermore, by following the observer suggestions and in accordance with the needs of students, the poste rwas improved.  In addition, animated picture elements were added to the poster. The implication is that the media becomes interesting. In consequence, it raises students' reading interest in the content which is to be conveyed. Moreover, the media was designed according to the characteristics and conditions of students in the classroom. As a result, the media can be effective and efficient in its use. Furthermore, suggestions from observers and adjusted to students' needs, the poster is then repaired and ready to be used in learning.

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.
