Mathematics communication, which includes writing, drawing, and expressing mathematics, is essential in learning mathematics. The teacher needs to design learning to develop the ability to communicate mathematically. Questions presented in the Rainbow Mathematics Card (RMC) allow participants to be educated to convey the ideas and concepts that become part of developing mathematics communication ability. The study aims to make mathematics communication ability TGT learning with RMC. A type study is a mixed method that is designed and experimented with in subjects research. Data was obtained through test mathematics ability communication before and after learning using a paired t-test. The results showed an enhanced mathematics communication ability through the TGT learning model with RMC.Komunikasi matematika yang meliputi menulis, menggambar, dan mengekspresikan matematika, sangat penting dalam pembelajaran matematika.

This study aimed to determine the students’ errors classified as Field Independent (FI) and Field Dependent (FD) in solving essay HOTS questions based on Watson criteria and to find out the causes of errors experienced by FI and FD types of students in finishing those questions. This was qualitative research which implemented the case study method. This research was carried out at Junior High School 3 Kepanjen Malang of 2019/2020 academic year. Research subjects were determined based on The Group Embedded Figures Test (GEFT) test results. From the test, two students were selected from each type of cognitive style. The applied data collection included tests and interviews. The qualitative data analysis applied four stages: data reduction, data presentation, conclusion, and verification. The results showed that FI students experienced errors in manipulating calculation, false conclusions, incorrect use of mathematical formulas, and false calculation. On the other hand, FD students had errors in mathematical operation signs, erroneous formula writing, irresponsive to problems, errors of manipulating calculation, and not writing mathematical formulas.

Written mathematical communication skills are an important concern in mathematics education. One way to assess these skills is by presenting students with open-ended problems. This study examines differences in written mathematical communication skills based on gender. The purpose of this study is to describe students’ written mathematical communication skills in solving open-ended problems from a gender perspective. The research employed a descriptive qualitative approach, with participants consisting of Grade VIII students from SMPN 2 Pamekasan, categorized into low, medium, and high levels of written mathematical communication skills. Data were collected through open-ended problem-solving tests to analyze students’ written mathematical communication based on gender. The findings indicate that: (1) students in the low-ability category were unable to fully meet the indicators, with both males and females scoring 58; (2) students in the medium-ability category were moderately able to meet the indicators, with both males and females scoring 75; and (3) students in the high-ability category demonstrated strong performance in meeting the indicators, with males scoring 83 and females 100. These results suggest that high-ability students are more effective in meeting the indicators of written mathematical communication, with observable differences based on gender. Female students tend to excel in written narratives, whereas male students show greater strength in visualization. Students with low and medium abilities still require support in notation, image proportion, and written explanations.

This study explored the challenges and opportunities of implementing Virtual Reality (VR) and Artificial Intelligence (AI) in mathematics education at secondary schools. While VR and AI offer transformative potential to enhance learning through immersive visualization of abstract concepts (e.g., 3D geometric modeling) and personalized adaptive instruction, their adoption faces barriers such as high costs, inadequate infrastructure, and insufficient teacher training. Nevertheless, stakeholder support from educators and students highlights their capacity to foster interactive and engaging learning environments. A mixed-methods approach combining interviews, questionnaires, and paired t-tests revealed significant improvements in student motivation and mathematical understanding post-VR implementation (t = -176.991, p < 0.001). Recommendations emphasize policy-driven financial support, localized content development, and scalable teacher training programs aligned with global best practices. By addressing systemic challenges, VR and AI can become pivotal tools for advancing equitable and innovative mathematics education.

Mathematical communication skills are crucial for mathematics learning, especially in understanding and solving word problems, which require conceptual understanding and systematic delivery of ideas. One way to help students acquire these skills is by implementing problem-based learning (PBL) methods, which enable them to be actively involved in the problem-solving and exploration process. This study aims to analyze students' written mathematical communication skills through the application of PBL to solving word problems. Subjects and Methods: The research method used was descriptive qualitative with 8 seventh-grade students as subjects. Data were collected through written tests, observations, and documentation, then analyzed based on three main indicators: concept visualization, use of mathematical symbols, and the ability to write explanations systematically. Results: According to the study, students were generally in the high category in written mathematical communication, with an average score of 78, but there were differences among students: four students were in the high category (83-100), one student in the medium category (75), and three students in the low category (58-67). Students in the high category were able to write solutions coherently and clearly, while students in the low category still had difficulty constructing mathematical arguments. PBL can help students in written mathematical communication, especially in understanding and solving story problems.

Mathematics is often considered an abstract science far removed from real life. The ethnomathematics approach aims to link mathematical concepts with local cultural practices. This study aims to explore the mathematical elements in the traditional houses of Hena Puan in Buano Utara Village and examine their potential as a source of mathematics learning. The method used is qualitative with an ethnographic approach. Data was collected through observation, interviews with traditional leaders, and visual documentation of the traditional house structure. The study results show that the Hena Puan traditional house contains mathematical concepts such as plane and solid geometry. Additionally, philosophical values related to the structure of the building, which have been passed down from generation to generation, were found. The implications of these findings suggest that the Hena Puan traditional house can serve as a relevant contextual learning resource, encourage student engagement, and strengthen local cultural identity. The implications of this study can be used as a source of contextual learning that makes mathematics learning more concrete, meaningful, and relevant to students' lives.
