Abstract

The development of digitalization technology in the world of education emphasizes the need for progressive learning innovation, not only focusing on procedural memorization, but it is important to integrate geometric concepts with cultural values ​​and STEM approaches. As for alternatives that answer these needs, the purpose of this study is to develop an Ethno-STEM based e-module that focuses on the Uma Lengge building as a geometry learning context to improve the mathematical representation abilities of junior high school students. In the development of this e-module, the ADDIE development model is used, which is Analysis, Design, Development, Implementation, Evaluation. In the data collection process by conducting observations, as well as using tests, andquestionnaires. The feasibility test obtained an e-module with a valid category in the material and design aspects, in addition, responses by students regarding the practicality of the module are in the practical category for use in learning, while the effectiveness test of the e-module showed an increase in students' representation abilities in the post-test results with a moderate to high increase, which indicates a significant difference from the pre-test results. So the Ethno-STEM based e-module focusing on the Uma Lengge building with the context of geometry material is effectively used to improve the mathematical representation abilities of junior high school students.

Abstract

The low level of numeracy literacy among students in the city of Bima and West Nusa Tenggara requires more contextual and relevant learning innovations that are relevant to local life and culture. This study aims to develop an Project Based Learning (PjBL) based ethno-STEM to improve the numeracy literacy of elementary school students. The research method used a research and development approach, which included needs analysis, model design, expert validation, limited trials, and effectiveness testing at SDN 11 Kota Bima. Data collection instruments consisted of questionnaires, observation sheets, and numeracy literacy tests. The validity test results showed that the Project Based Learning (PjBL) based ethno-STEM met the criteria for content, language, and implementation feasibility. The application of the model in field trials provided a significant improvement in students' numeracy literacy skills compared to conventional learning, as indicated by higher post-test scores and positive responses from teachers and students. These findings confirm that the integration of local culture in project-based learning effectively improves students' understanding of mathematical concepts and problem-solving skills. This study concludes that the Project Based Learning (PjBL) based ethno-STEM can be an alternative contextual and relevant learning innovation to improve numeracy literacy in elementary schools

Abstract

This study aims to analyze and describe students’ mathematical problem-solving (MPS) ability through the implementation of PBL treatment on the topic of the perimeter of plane figures in fifth-grade elementary students. The research employed a quantitative approach with a pre-experimental design, specifically a one-shot case study. The participants consisted of 21 fifth-grade students selected using a purposive sampling technique. The research instrument was a problem-solving test that had been validated for both validity and reliability. The results indicate that PBL contributes significantly to students’ achievement in problem-solving ability. Based on the one-sample t-test, the significance value obtained was < 0.001, indicating that the proposed hypothesis was accepted at the 0.05 significance level. Furthermore, the students’ mean MPS score was 85.39, with a median of 90 and a skewness value of -1.320, which signifies a left-skewed distribution, meaning that most students achieved high scores. Furthermore, when viewed across the four problem-solving procedures, only the third stage—solving problems according to the determined procedures—had a percentage below 70%. This lower percentage was primarily due to inaccuracies in calculation processes, which affected the final results. Such errors were more likely caused by miscalculations rather than by the selection of inappropriate problem-solving strategies.

Abstract

Financial statements are a fundamental element of accounting and serve as the basis for strategic decision-making, requiring mastery of accounting principles and quantitative skills. This descriptive qualitative study aims to describe the mathematical concepts and their applications in the preparation of financial statements by accounting students. Data were collected through interviews, student grades, and financial statement documents. The results indicate that the essential mathematical concepts include basic arithmetic, algebraic equations (e.g., ), ratios/percentages, basic statistics, and rounding. Although all students employed the same concepts, the depth and level of integration varied. Students categorized as “very good” demonstrated the ability to link calculations with transaction reasoning, analyze ratios across periods, apply statistical tools for diagnosis, and maintain accuracy control, resulting in financial reports that are meaningful and actionable. In contrast, students in the “fair” category tended to be procedural, focusing on numerical accuracy but lacking interpretation of the underlying meaning. It is therefore recommended that mathematics instructors develop learning models that integrate mathematical theory with direct accounting practice. Project-based or real case study approaches can help students better understand the relationship between mathematical computation and the actual outcomes of financial reporting.

Abstract

Mathematical communication skills are an essential competency in 21st century mathematics learning. Traditional approaches, which are generally abstract and lack context, are often a barrier to their development. This study aims to systematically examine various studies related to mathematical communication in traditional game-based mathematics learning in the cultural context of the archipelago. The method used is Systematic Literature Review (SLR) with PRISMA guidelines, as many as 15 articles published in 2020–2025 obtained from the selection of Google Scholar, ERIC, and Dimensions databases. The results of the study analysis showed that traditional games such as engklek, congklak, and marbles were most often used in learning and were proven to be effective in improving students' mathematical communication both verbally and in writing. This approach also contributes to increased learning motivation, concept understanding, and character building. These findings support the relevance of ethnomathematical approaches that link mathematics to local cultural practices. It was also found that learning mathematics that integrates traditional games not only strengthens academic competence, but also fosters an appreciation of contextual and meaningful local wisdom for Indonesian students.
