Abstract

This study aims to identify and analyze trends in commognitive research in mathematics education, focusing on four main components: word use, mediators, rules, and narratives. Additionally, this study seeks to explore how commognitive theory is applied in mathematics education research and to identify research gaps that can be further developed. The method used in this study is a Systematic Literature Review (SLR), with article searches conducted through the Google Scholar, SINTA, and Scopus databases within the 2015–2025 timeframe. Articles were selected based on strict inclusion and exclusion criteria, resulting in the final analysis of five relevant articles. Each article was classified based on research methods, key findings, and contributions to commognitive theory in mathematics education. The findings indicate that visual mediators and routines are the most frequently studied commognitive components, particularly in the context of technology use and touchscreen interaction in mathematics learning. Additionally, commognitive conflicts were commonly observed in the transition from school to university, particularly in students' understanding of mathematical terminology (word use) and the application of mathematical communication rules (rules). The primary finding of this study reveals that students with higher mathematical understanding tend to construct more argumentative mathematical narratives, while students with lower comprehension tend to rely on mechanical procedures without fully grasping the underlying concepts. For future research, further exploration of word use and narratives is recommended, particularly in the context of elementary and secondary school education.

Abstract

The aim of this study is to examine problem-solving assessments to measure the profile of students' written mathematical communication skills across low, medium, and high ability levels. The problem-solving assessment used includes a problem-solving test and an interview guide. This study is descriptive research with a qualitative approach. The research subjects consist of three students: one with low mathematical ability, one with medium mathematical ability, and one with high mathematical ability. High-ability students meet four indicators of written mathematical communication skills, which include writing down the known information and questions from the given problem and sketching a diagram, understanding mathematical ideas in planning and formulating rules or presenting formulas, interpreting information in carrying out the problem-solving plan, and reviewing/checking the correctness of the answers/conclusions. Medium-ability students meet one indicator of written mathematical communication skills, which is understanding mathematical ideas to plan and formulate rules or present formulas. Low-ability students do not meet any of the indicators of written mathematical communication skills

Abstract

Kemampuan komunikasi matematis merupakan aspek penting dalam pembelajaran matematika karena memungkinkan siswa untuk mengungkapkan ide matematika secara jelas dan sistematis. Perbedaan gender dalam komunikasi matematis telah menjadi fokus berbagai penelitian, namun kajian spesifik dalam materi statistika masih terbatas. Oleh karena itu, penelitian ini bertujuan untuk mendeskripsikan kemampuan komunikasi matematis siswa laki-laki dan perempuan dalam mata pelajaran Statistika. Jenis penelitian ini menggunakan pendekatan deskriptif kualitiatif dengan melibatkan dua siswa yang berbeda gender yakni satu siswa laki-laki dan satu siswa perempuan. Data dikumpulkan dengan menggunakan instrumen tes kemampuan komunikasi matematis dan wawancara. Analisis data yang dilakukan meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Untuk menguji keabsahan data menggunakan triangulasi metode. Hasil penelitian menunjukkan bahwa siswa perempuan lebih sistematis dalam menyajikan data dalam bentuk tabel dan diagram serta lebih teliti dalam menjelaskan langkah-langkah perhitungan. Sebaliknya, siswa laki-laki cenderung hanya menampilkan hasil akhir tanpa menjelaskan proses perhitungannya secara rinci. Selain itu, siswa perempuan menunjukkan kemampuan argumentasi yang lebih jelas dan terstruktur dibandingkan siswa laki-laki yang lebih ringkas dalam menjawab. Penelitian ini mengimplikasikan perlunya strategi pembelajaran berbasis gender dan upaua peningkatan komunikasi matematis melaui diskusi sehingga dapat kemampuan komunikasi matematis siswa dapat setara.
