Culture-Based Geometry Teaching Tool: An Effort To Instill Love of North Sumatra's Local Wisdom in Students

Abstract

The primary objective of this study was to create educational resources rooted in the indigenous knowledge of North Sumatra. Employing the 4-D development model, the research utilized both qualitative and quantitative analyses. The outcome was the production of a geometry learning tool, subjected to assessments of validity, practicality, and efficacy. The tool's testing revealed notable improvements in students' mathematical problem-solving skills between Trial I and Trial II, with indicators displaying an average increase of 0.35%, 3.99%, 16.22%, and 8.32%, respectively.
