Abstract

Ethnomathematics is the relationship between culture and mathematics found in society's habits, where people have unconsciously applied mathematical concepts in their culture or habits. The custom referred to in this study is what is done by batik in making one batik sheet every time. The purpose of this study was to describe ethnomathematics on cassava leaves in the production house Daweea Batik Bondowoso East Java. This research is qualitative research with an ethnographic approach. The subject of this study was the craftsmen in the Daweea Bondowoso Batik production house. Data collection methods used are observation, interviews, and documentation. The observation was carried out by the researcher himself and assisted by two observers who were provided with observation guidelines. Interviews were conducted to artisans in Daweea Bondowoso batik production house, while the documentation was carried out by the researcher himself using a camera recorder. The results of this study indicate the existence of ethnomathematics in cassava leaves batik painting. Geometry concepts or elements found include points, lines, angles, flat shapes (rectangles, squares), congruence, concordance, equations, and geometric transformations (dilation).

Abstract

Geometric intuition is a cognitive skill that supports students in solving geometry problems, one of the more challenging branches of mathematics. This study explores students' ability to create and manipulate geometric figures when working on Higher Order Thinking Skills (HOTS) problems involving cuboids. Employing a qualitative descriptive approach, the study involved 29 eighth-grade students. Data were collected through HOTS-based problem-solving tests and validated interview protocols. Students' abilities to mentally construct and transform geometric figures were assessed using two indicators: (1) visualizing shapes based on imagination and (2) generating new geometric configurations. The findings revealed that most students were unaware of alternative geometric forms embedded within the problem context. The study concludes that students across all performance levels, from low to high, demonstrated the ability to visualize shapes based on imagination. However, only students in the medium category were able to generate a new shape in one problem, whereas those in the high category successfully created new shapes in two problems.
