Abstract

This study investigates the enhancement of students' mathematical and logical thinking skills through kite-making activities using the STEM approach. Conducted with 28 ninth-grade students at SMP Negeri 03 Bengkulu Tengah, this qualitative descriptive research utilized observation, documentation, and interviews for data collection. Data were analyzed using the Miles and Huberman model, focusing on integrating geometry, measurement, and symmetry within the kite-making process. The findings reveal that STEM-based kite-making activities significantly improve students' logical reasoning and problem-solving skills by contextualizing abstract mathematical concepts into practical tasks. Students demonstrated the ability to sequence steps systematically, provide logical arguments, and draw accurate conclusions. These results emphasize the potential of project-based learning in fostering higher-order thinking skills. This study suggests that incorporating similar activities in the curriculum can enhance students' cognitive and practical competencies. Further research is recommended to explore its implementation across diverse educational levels and environments.

Abstract

Mathematics knowledge in schools should be sourced from scholarly knowledge. Education not sourced from scholarly knowledge will risk errors in concepts, such as invalidly taught material, that can lead to misconceptions. This study aims to analyze the transposition of knowledge on the concept of lines and angles from scholarly knowledge to knowledge to be taught. This study uses a qualitative descriptive approach. The data source in this study, namely scholarly knowledge, was obtained by analyzing books in universities, while knowledge to be taught was obtained by analyzing mathematics textbooks used in schools. This study's results show a transposition process in the concept of lines and angles, namely in the definition of lines, the types of lines, the position of two lines, and the relationship of angles in two parallel lines. This research can later be the basis for improving mathematical knowledge so that student's understanding of the concept of lines and angles is expected to be more complete based on scholarly knowledge.

Abstract

This study examines ethnomathematics in the architecture of the Kepahiang Traditional House or Bubungan Lima. Using an ethnographic qualitative approach, this study focuses on identifying mathematical concepts in the physical form, structure, and philosophy of buildings. Data were collected through participatory observation, in-depth interviews with cultural experts, and documentation. The results of the study show that this traditional house is rich in geometric applications, including flat (rectangles, triangles), spatial (limas, cylinders), geometric transformations (reflection, translation, rotation), and lines (parallel, perpendicular) in ornaments and structures. In addition, there was also a traditional body-based measurement system and construction techniques without iron nails that reflected the implicit mathematical understanding of the Rejang people of proportion, precision, and structural strength. All of these findings confirm that ethnomathematics in the Kepahiang Traditional House is a manifestation of local wisdom rich in mathematical meaning. This is highly relevant as a context-based, culture-based learning resource to bridge abstract mathematical concepts while fostering students' appreciation of their local cultural identity.
