Abstract

This study aims to develop an ethnomathematics-based pop-up book as a learning medium, integrating geometric concepts within the context of traditional Lampung houses, to enhance students' conceptual understanding of mathematics and to evaluate the responses of teachers and students as well as the effectiveness of the media. The research employed the Borg & Gall development model with seven steps: data collection, planning, initial draft development, preliminary testing, product revision, main field testing, and dissemination and implementation. Data were analyzed using qualitative and quantitative descriptive methods. Validation results indicated that the media fell into the "highly feasible" category, with a score of 90% from material and media experts. Small-scale testing received a "very interesting" response of 92%, while large-scale testing achieved a 94% positive response from 29 students. Improvement in conceptual understanding was evidenced by an N-Gain score of 0.89 (high category), and the media’s effectiveness was shown by an effect size of 1.06 (effective category). The findings imply that the ethnomathematics-based pop-up book is effective in supporting culturally responsive mathematics learning and can serve as an innovative and contextual alternative learning medium.

Abstract

Design interactive worksheets based on Canva and Liveworksheets is the aim of this project to assist students in developing their social arithmetic problem-solving abilities. The research methodology employed was research and development (R&D) using the ADDIE model, which comprises the phases of analysis, design, development, implementation, and evaluation. The participants were seventh-grade students and a math teacher from SMP Negeri 5 Kotabumi, Lampung. Tests of problem solving skills, observations, interviews, and questionnaires were employed to gather both qualitative and quantitative data. Subject matter experts' validation assessment, which received a score of 0.84 (very valid), media experts' score of 0.90 (valid), and students' and instructors' practicality index scores of 0.80 (practical) and 0.90 (very practical) all demonstrate the study's findings. The effectiveness of the interactive worksheet developed can be seen based on the testing of the n-gain data hypothesis listed in the significance section (2-tailed), which is 0.0017. There is a difference in the improvement of problem solving skills for students who use interactive worksheets. The novelty of this research lies in the development of interactive worksheets based on the Canva and Liveworksheet digital platforms, which integrate visualization, direct interaction, and automatic feedback to improve students' problem solving skills in social arithmetic. Thus, these findings show that the worksheets are valid, practical, and effective in improving students' problem solving skills.

Abstract

Background: Although Self-Regulated Learning (SRL) has been extensively studied in mathematics education, existing studies primarily report empirical findings, while the intellectual structure, thematic evolution, and emerging research directions of the field remain insufficiently synthesized. This limitation hinders a comprehensive understanding of research development and future priorities.Aims: This study aims to analyze trends in publications and citations, the most influential authors and journals, co-occurrence patterns of keywords, temporal trends in research topics, and the density of research topics related to SRL in mathematics education to support Quality Education.Methods: A quantitative bibliometric approach was employed using the Dimensions database. Publications published between 2016 and 2025 were retrieved using the keywords "Self-Regulated Learning" and "Mathematics Education." Of the 181 records identified, 91 journal articles met the predefined inclusion criteria and were analyzed using VOSviewer (version 1.6.20). Performance analysis was conducted to examine publication and citation trends, while science mapping using co-occurrence, overlay, and density visualizations identified the intellectual structure and thematic development of the field.Result: The results indicate that publications and citations related to SRL in mathematics education have increased during the 2016–2025 period. Furthermore, Tatang Herman and Dadang Juandi were the authors with the highest number of publications three each while the Journal of Physics: Conference Series was the journal with the highest number of publications, totaling six. Co-occurrence analysis identified three interconnected research clusters dominated by motivation, achievement, self-efficacy, engagement, feedback, and learning environment. Overlay visualization revealed a shift from studies emphasizing individual learner characteristics toward technology-supported learning, instructional frameworks, and learning environments. Density visualization showed that achievement, engagement, feedback, and quantitative empirical approaches remain the most intensively studied themes.Conclusion: This study advances current understanding by identifying emerging themes and research gaps in SRL within mathematics education. The findings provide evidence-based directions for future research integrating pedagogical, psychological, and technological perspectives, while informing the design of innovative mathematics learning.

Abstract

Abstract The development of Generative Artificial Intelligence (Gen-AI) has influenced students’ learning patterns, including in mathematics education at the university level. This study aims to analyze the perceptions of students in the Mathematics Education Program at Universitas Muhammadiyah Kotabumi regarding the use of Gen-AI in terms of its application, intensity, accuracy, ethics, and impact on mathematics learning. This study employs a descriptive quantitative approach using a survey method, involving the distribution of questionnaires to 35 Mathematics Education students. The data were analyzed descriptively to identify patterns and trends in student perceptions. The results indicate that ChatGPT is the most widely used Gen-AI platform. The intensity of use occurs in short durations during each learning session, specifically less than 10 minutes. In terms of accuracy, students generally assessed that Gen-AI is capable of providing explanations consistent with mathematical concepts, although their level of confidence in the consistency of its answers remains moderate. From an ethical standpoint, the majority of students were open about acknowledging their use of Gen-AI and did not simply accept AI answers without critical evaluation. Meanwhile, regarding its impact, has begun to show signs of dependence on Gen-AI among some students, although overall it has not yet completely replaced the practice of verifying answers or academic interactions with professors and classmates. Overall, students tend to have a positive perception of the use of Gen-AI in mathematics learning, but its use should be guided as a learning support tool that continues to emphasize mathematical reasoning, information verification, independent learning, and academic integrity. Keyword: Generative AI; Student Perceptions; Mathematics Learning.
