Abstract

Mathematics is often considered an abstract and difficult subject for students to grasp. Understanding geometry, in particular, requires visualization skills that many students struggle with. This research aims to assess students' understanding of geometry through the ethnomathematics approach using Ngadas Temple as a learning medium. Therefore, this study implements ethnomathematics-based student worksheets (LKS) in Ngadas Temple, Malang, East Java. The LKS focuses on geometry, particularly plane figures, by engaging students from grades 4 to 6 Elementary School 1 Ngadas in interactive learning. Conducted as part of the Sisis Indonesia (SINESIA) volunteer program in Ngadas from December 15 to 21, 2024, this research employed a descriptive method, where students’ responses were analyzed based on correctness, misconceptions, and partial understanding. Data collection methods included written tests, observations, and documentation. Findings indicate that students could identify plane figures but struggled with spatial visualization and recognizing 3D shapes. Furthermore, while some students could determine area and perimeter, others faced difficulties in measurement and calculations. This study highlights the effectiveness of ethnomathematics in fostering students’ engagement and comprehension through real-world applications.

Abstract

This study aims to examine the quality of the Missouri Mathematics Project (MMP) learning model assisted by the Teachmint application on students' geometric literacy. Geometric literacy is part of mathematical literacy related to understanding geometric concepts in everyday life. This study uses a mixed method with a sequential explanatory design. Quantitative data were collected through geometric literacy tests and analyzed using statistical tests, while qualitative data were obtained from observations and interviews. The experimental class in this study was Class X E-8, while the control class was Class X E-9. The results showed that the quality of learning at the planning stage obtained a very valid category with an average device validation of 88.73%. At the implementation stage, the implementation of learning showed very good results with an average teacher activity of 85.6% and student activity of 83.3%. The learning evaluation showed that the MMP model assisted by Teachmint was effective in improving geometric literacy, with the average final score of students exceeding the Learning Objective Achievement Criteria, the proportion of classical completeness reaching 90%, and an increase in students' geometric literacy by 62%. These findings confirm that the integration of structured practice-based learning models with digital technologies such as Teachmint can significantly improve the quality of students' mathematics learning and geometric literacy.
