Abstract

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.

Abstract

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.

Abstract

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.

Abstract

This community service activity aimed to support the improvement of mathematics learning quality at MTsN 4 Cirebon by assisting teachers in developing innovative teaching aids. The urgency of this program lies in the abstract nature of spherical geometry, which makes it difficult for students to grasp elements such as radius, diameter, center point, surface area, and volume when explained only verbally. At the same time, teachers are not yet accustomed to independently creating or using teaching aids. The specific goal of this activity was to introduce and guide the use of the “Bolundarsi” teaching aid as a visual and manipulative medium for learning spheres. The method employed was Participatory Action Research (PAR) through socialization, workshops, and classroom mentoring, with data collected via interviews, questionnaires, and observations. The results showed improved teacher skills, high participation, and enhanced student understanding and engagement. Teachers and students responded positively, indicating that Bolundarsi makes learning more interactive and supports a more concrete understanding of spherical concepts.

Abstract

This study aims to describe the forms of mathematical misconceptions of students in solving contextual problems in fractional number material. The research used a descriptive qualitative approach and was carried out at SD Negeri 1 Gandasoli, Kuningan Regency. The subjects of the study were all students of class V totaling 39 people. Data was obtained through a written test in the form of contextual description questions about fractional numbers that have gone through the validity test stage. Based on the test results, students were classified into three levels of mathematical ability, namely high, medium, and low, then 9 students were selected as sample subjects for in-depth analysis. Data analysis is carried out through the stages of data reduction, data presentation, and conclusion drawn. The results of the study show that students still experience various types of mathematical misconceptions, including misconceptions of translation, signs, calculations, systematic, concepts, and strategies. Misconceptions of translation and signs were found at all levels of mathematical ability, while calculating, systematic, and conceptual misconceptions appeared in students of medium and low ability. Strategic misconceptions are only found in students with low mathematical ability. These findings show that the complexity of misconceptions increases as students' mathematical ability levels decrease, so learning that emphasizes understanding concepts and meaningful problem-solving in fractional number material is needed.

Abstract

Penelitian ini mengkaji bagaimana mahasiswa mengalami dan memaknai tahapan pemecahan masalah Polya saat mengerjakan tugas geometri dalam lingkungan electronic Problem-Based Learning (e-PBL) yang diimplementasikan melalui sistem manajemen pembelajaran berbasis Moodle yang dikustomisasi. Penelitian ini menggunakan desain deskriptif kualitatif dengan sumber data berupa artefak pemecahan masalah tertulis, wawancara semi-terstruktur, dan jejak digital selama e-PBL. Data dianalisis menggunakan analisis tematik Braun dan Clarke dengan pengodean deduktif berdasarkan empat tahap Polya dan pengodean induktif untuk menangkap pola penalaran yang muncul. Hasil penelitian menunjukkan bahwa pemecahan masalah berlangsung secara dinamis dan rekursif. Tahap memahami dan merencanakan melibatkan penafsiran ulang representasi multimodal, sedangkan tahap pelaksanaan ditandai oleh pergeseran representasi yang memperjelas konsep. Prompt reflektif dalam e-PBL mendukung deteksi kesalahan dan penguatan konsep, serta menegaskan peran tahap evaluasi. This study examines how students experience and interpret Polya’s problem-solving stages while working on geometry tasks in an electronic Problem-Based Learning (e-PBL) environment implemented through a customized Moodle based learning management system. Using a qualitative descriptive design, data were collected from written problem-solving artefacts, semi-structured interviews, and digital traces generated during e-PBL activities. The data were analyzed using thematic analysis following Braun and Clarke, combining deductive coding based on Polya’s four stages with inductive coding to capture emerging reasoning patterns. The findings indicate that problem-solving is enacted as a dynamic and recursive process rather than a linear sequence. Understanding and planning involve repeated reinterpretation of multimodal representations, while execution is characterized by representational shifts that support conceptual clarity. Reflective prompts in e-PBL facilitate error detection and conceptual consolidation, highlighting the importance of the evaluative stage.
