Implementation of Ethnomathematics Student Worksheet in Ngadas Temple: Interactive Geometry Learning
Main Article Content
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.
