The Framework of Ethnomathematics Learning Activities Based on Majapahit Culture with STEAM Approach: Utilizing Used Cardboard for Miniature Building Media Development in Enhancing the Students’ Creative Thinking Abilities
Creative thinking is one of the 21st-century skills that can be developed through learning mathematics. Mathematics learning involves the culture students already know to facilitate students’ understanding. Mojokerto City carries the slogan Spirit of Majapahit, giving the city’s layout a nuance. The concept of two-dimensional and three-dimensional shapes with a Majapahit nuance can be used as a source of ethnomathematics learning to enhance creative thinking skills. Teaching about two-dimensional shapes can be used as teaching material to improve creative thinking skills. Creative thinking skills are an individual’s ability to find new ways, strategies, ideas, or concepts about how to obtain a solution to a problem. Students’ thinking skills may need to be higher. One reason is that the teaching methods used so far have yet to highlight the concept of two-dimensional shapes related to ethnomathematics. Therefore, this study will apply an ethnomathematics-based learning activity framework based on the Majapahit culture with a STEAM approach by using cardboard to make miniature buildings to improve students’ creative thinking skills. The most suitable approach is STEAM since it integrates five disciplines to enhance further creative thinking skills in solving problems related to two-dimensional and spatial constructions.
