This quantitative experimental study aims to examine the effect of mathematical representation ability and mathematical spatial ability on students’ mathematics learning outcomes, with gender as a moderating factor. The population consisted of 74 third-semester Mathematics Education students at UIN Syekh Nurjati Cirebon during the 2024/2025 academic year. A sample of 30 students was selected using purposive sampling. Validated test instruments were used to measure mathematical representation ability, spatial ability, and learning outcomes. Data were analyzed using simple and multiple linear regression. The results show that for female students, both abilities significantly and positively influenced learning outcomes (p < 0.05). For male students, only mathematical spatial ability showed a significant effect (p < 0.05). These findings suggest that female students may be better at integrating representational and spatial skills in mathematical learning than their male counterparts

Kemampuan dalam memecahkan masalah matematika merupakan aspek krusial yang perlu dikembangkan oleh siswa agar mampu mengaplikasikan konsep-konsep matematika dalam situasi kehidupan nyata, bukan hanya sebatas memahami teori. Penelitian ini bertujuan untuk mengkaji kemampuan siswa kelas V di SDN 1 Dawuan, Kabupaten Cirebon, dalam memecahkan permasalahan matematika pada topik pecahan, dengan fokus pada aspek pemahaman masalah, perencanaan solusi, dan evaluasi hasil penyelesaian. Pendekatan deskriptif kualitatif digunakan dalam penelitian ini, dengan enam siswa yang dikategorikan ke dalam tiga level kemampuan tinggi, sedang, dan rendah. Instrumen yang digunakan yaitu tes uraian berjumlah sembilan soal terkait pemecahan masalah dalam materi pecahan. Analisis data dalam penelitian ini mencakup tahapan teknik reduksi data, penyajian data, serta penarikan kesimpulan. Temuan penelitian menunjukkan bahwa dari enam peserta didik, sebanyak dua siswa (33%) tergolong dalam kategori kemampuan pemecahan masalah tinggi, empat siswa (67%) berada pada kategori sedang, dan tidak satu pun siswa yang termasuk dalam kategori rendah (0%). Meskipun sebagian besar siswa menunjukkan kemampuan yang baik, banyak yang masih mendominasi kategori sedang. Beberapa siswa tidak menuliskan informasi dan pertanyaan secara lengkap serta kesulitan dalam memilih operasi yang tepat. Selain itu, baik siswa kategori tinggi maupun sedang sering tidak memeriksa kembali jawaban mereka. Temuan ini menekankan pentingnya melatih siswa untuk menyelesaikan masalah dengan teliti dan memeriksa penyelesaian akhir. The ability to solve mathematical problems is a crucial aspect that students need to develop so they can apply mathematical concepts in real-life situations, not just understand the theory. This study aims to assess the ability of fifth-grade students at SDN 1 Dawuan, Cirebon Regency, in solving mathematical problems on the topic of fractions, with a focus on the aspects of problem understanding, solution planning, and evaluation of the results of the solution. A qualitative descriptive approach was used in this study, with six students categorized into three levels of high, medium, and low ability. The instrument used was a descriptive test consisting of nine questions related to problem solving in the material of fractions. Data analysis in this study included the stages of data reduction techniques, data presentation, and drawing conclusions. The research findings showed that of the six students, as many as two students (33%) were classified as having high problem-solving ability, four students (67%) were in the medium category, and none of the students were included in the low category (0%). Although most students showed good abilities, many still dominated the medium category. Some students did not write complete information and questions, and had difficulty choosing the correct operation. In addition, both high and medium category students often did not recheck their answers. These findings emphasize the importance of training students to solve problems carefully and check their final solutions.

Social skills play an important role in mathematics learning because they support communication, collaboration, and the presentation of ideas. At the same time, mathematical representation is a key process in expressing concepts in verbal, visual, and symbolic forms. This study aims to determine the influence of social skills on students' mathematical representation ability. A quantitative approach with a one-shot case study design was employed. The population consisted of 605 of an elementary school students at Cirebon, Indonesia in the 2024/2025 academic year, and a cluster random sampling technique was used to select 31 students as the sample. Data were collected through a mathematical representation test and a social skills questionnaire. The results showed that social skills significantly influence students' mathematical representation ability, contributing 67.5%, while the remaining 32.5% is explained by other factors. The regression analysis produced a coefficient of 0.775, indicating that for every one-unit increase in the social skills, the mathematical representation ability score is predicted to increase by 0.775 units. These findings emphasize the importance of developing social skills to enhance mathematical representation and create more effective learning experiences.

This quantitative study aims to examine the influence of the learning environment on students’ mathematical representation abilities. The research is motivated by the relatively low levels of mathematical representation skills observed among students, which may be associated with variations in the quality of their learning environments. The study was conducted at a junior high school in Cirebon during the 2024/2025 academic year, involving 30 students selected through purposive sampling. Data were collected using a questionnaire to measure students’ perceptions of the learning environment and a test instrument to assess their mathematical representation abilities, including verbal, visual, and symbolic representations. The findings indicate that the learning environment has a significant influence on students’ mathematical representation abilities. However, the results also reveal that both the quality of the learning environment and students’ mathematical representation abilities are relatively low. Statistical analysis shows that the learning environment accounts for 9.3% of the variance in students’ mathematical representation abilities, while the remaining 91.7% is explained by other factors beyond the learning environment. Future studies should explore the influence of additional factors such as learning motivation, instructional methods, and cognitive abilities on students’ mathematical representation skills. Moreover, research involving larger and more diverse populations is recommended to enhance the generalizability and applicability of the findings.

This study aims to examine the effect of the Aptitude Treatment Interaction (ATI) learning model assisted by the snakes and ladders game media on students' critical mathematical thinking skills. The background of this study is the low critical thinking skills due to the dominance of traditional learning methods that are less varied and the minimal use of interesting media. The ATI model adjusts the learning approach to the characteristics of students, while the snakes and ladders game creates a fun and interactive learning atmosphere. This study uses a quantitative approach with a quasi-experimental design of the pretest-posttest control group type. The sample consisted of 57 grade VIII students selected by cluster random sampling from a population of 419 students, then divided into experimental and control groups. The treatment was given for eight meetings. The instrument used was a mathematical critical thinking ability test. The results of the Mann-Whitney test showed a significance value of 0.000 (p <0.05), which means that there is a significant effect of the application of the ATI model assisted by the snakes and ladders media on improving students' critical thinking skills. The effect size value of 0.522 indicates that the effect is quite large. This study has novelty because it integrates the ATI model with snakes and ladders media, which has never been studied before in the context of mathematical critical thinking skills. This model can be an alternative effective and interesting learning strategy in mathematics learning.
