Abstract

Previous research has highlighted the challenges of improving students' mathematical skills, particularly in connecting mathematical concepts to everyday life and developing strong mathematical habits of mind. This research aims to integrate problem-based learning (PBL) into a mathematics module to enhance mathematical connection abilities and mathematical habits of mind. The ADDIE method was employed to achieve this goal, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The findings indicate that media, material, and language experts deemed the module highly suitable. Furthermore, the product was rated as highly practical based on teacher assessments, student responses, and observations during implementation. Effectiveness tests of the product, conducted through MANOVA, t-tests, and N-gain tests, revealed that the module is highly effective in enhancing students' mathematical connection abilities and moderately effective in improving their mathematical habits of mind. These findings underscore the importance of integrating digital learning technologies to increase the module's engagement and accessibility.

Abstract

This research explores the integration of ethnomathematics and virtual reality (VR) to digitize Indonesian museums, enhancing educational accessibility and cultural preservation. The study aims to investigate how VR technology can visualize and communicate mathematical knowledge embedded in Indonesian cultural artifacts, particularly within traditional crafts, architecture, and measurement systems. Employing a qualitative approach with a design-based research (DBR) methodology, data were gathered through observation, interviews, and artifact analysis in several Indonesian museums. VR-based ethnomathematics models were developed, tested, and revised iteratively. Findings show that VR facilitates immersive experiences and improves student engagement in learning mathematics through cultural context. This approach contributes to mathematics education by integrating technology and local culture within the framework of ethnomathematics. Integrating ethnomathematics and virtual reality (VR) in museum digitalization has significant implications for mathematics education research. VR-based applications in ethnomathematics offer inclusive opportunities for students in remote or underserved areas to experience museum-based learning. This addresses educational equity and access, especially for regions where physical museum visits are not feasible.

Abstract

Mathematical critical thinking remains an essential yet underdeveloped competency in 21st-century mathematics learning, particularly when instruction lacks meaningful cultural context. At SMP Pembangunan Piyungan, number-topic instruction predominantly emphasizes procedural over contextual and reflective thinking, signaling an urgent need for culturally-grounded, innovative learning media. This study examines the improvement trend in seventh-grade students' mathematical critical thinking ability through E-Worksheets integrating Ethno-Modeling—connecting mathematical concepts with Piyungan's local cultural context—and the Tri-N approach (Niteni, Nirokke, Nambahi), which systematically guides students through observing, imitating, and developing ideas. Employing a time-series design, data were collected via mathematical critical thinking tests administered at each intervention meeting and analyzed quantitatively by tracking average score trends over time. Results demonstrate a consistent upward trend, with average scores rising from 89.09 at the first meeting to 96.18 at the seventh—indicating that E-Worksheets grounded in local cultural contexts and structured Tri-N learning stages effectively foster students' mathematical critical thinking development. These findings position Ethno-Modeling-based E-Worksheets integrated with Tri-N as a promising alternative medium for meaningful and culturally responsive mathematics learning.

Abstract

Studies examining changes in mathematical abilities among students with high levels of nomophobia through AI-based intervention designs remain very limited. This study aims to identify the effect of AI technology on the mathematical conceptual understanding of students with high nomophobia tendencies. This study employed a Single Subject Research method with an ABA design consisting of baseline 1, intervention, and baseline 2 phases. The subject was a student with nomophobia selected purposively. Data were collected through mathematical conceptual understanding tests in each session and analyzed visually within and across conditions. The results showed that in phase A1, the subject experienced difficulties in understanding function concepts. In phase B, conceptual understanding improved, although the subject still had difficulty representing functions in graphical form. In phase A2, the subject’s performance was more stable than in phase A1, indicating retention after the intervention ended. Thus, AI-assisted learning had a positive impact on improving students’ mathematical conceptual understanding.

Abstract

Tri-N or Niteni, Nirokake, Nambahi (observing, imitating, adding) is a learning approach initiated by the Father of Indonesian Education, Ki Hadjar Dewantara. Tri-N is an adaptable approach that is easy to apply in every learning material, including mathematics. This research and development aims to develop an e-worksheet based on Tri-N for system of linear equations in two variables to improve junior high school students' creative thinking skills using the Liveworksheet Platform. The study employed the ADDIE development model, with stages: analysis, design, development, implementation, and evaluation although it was limited to the development stage to focus on validity and practicality. The results of this research include: (1) an e-worksheet based on Tri-N in a two-variable linear equation system has been produced to improve the creative thinking skills of junior high school students, (2) the validity test of the e-worksheet developed shows that 98.60% is categorized as very valid, and (3) the practicality test of the e-worksheet shows that 67.14% of students strongly agree and 31.90% of students agree on each aspect of the assessment. So, it can be concluded that e-worksheet based on Tri-N in a two-variable linear equation system is valid and practical for improving junior high school students' creative thinking skills. It is hoped that the research can become a reference in further research to test the effectiveness of the e-worksheet.
