Abstract

Teaching mathematics through emerging everyday themes has proven to be promising, as highlighted by research in Mathematical Modeling. Ethnomodeling uses Modeling to connect academic and cultural knowledge, thereby inspiring a variety of thematic possibilities. This study is part of a broader doctoral research project and aims to communicate how Ethnomodeling inspired 9th-grade students in the final years of middle school to raise problem-based questions and solve them through Mathematical Modeling. We found that the theme of constructing hip roofs sparked students' curiosity, particularly regarding material waste management in the discussed context, leading them to reflect on the importance of such considerations for decision-making.
