GEOMETRIC TESSELLATIONS IN AMANUBAN PLAITING CRAFT: ETHNOMATHEMATICAL PERSPECTIVES AND THEIR INTEGRATION INTO MATHEMATICS LEARNING

Abstract

Tessellation refers to the complete and repetitive covering of a plane using geometric shapes without gaps or overlaps. While firmly grounded in mathematics, tessellations also manifest in cultural expressions, such as in the patterns of Amanuban palm leaf plaiting craft. This study explores the application of geometric transformations within an ethnomathematical framework, focusing on the structure and motifs found in traditional plaiting crafts. The research identifies three types of tessellations regular, semi-regular, and non-regular (locally referred to as Duma) embedded in Amanuban plaiting designs. A qualitative approach was employed, incorporating participatory observation, semi-structured interviews, and visual documentation involving experienced artisans. These cultural practitioners possess deep knowledge of the symbolic meanings and technical processes behind the motifs. The findings reveal that geometric transformations including translation, reflection, rotation, and dilation are applied either consciously or intuitively, resulting in unique aesthetic and cultural patterns. This study confirms that traditional crafts can serve as valuable contextual resources for teaching mathematical concepts, particularly in geometry and tessellation. Integrating cultural heritage into mathematics education enhances students’ understanding of mathematics as a discipline embedded in social and cultural contexts. The research contributes to the development of culturally responsive pedagogy and underscores the educational value of local wisdom in fostering meaningful and inclusive mathematics learning.
