Improving students’ mathematical complex problem solving using the exploration of Bugis typical phinisi boat patterns

Solving complex problems is crucial for navigating the 21st century’s development. The primary measure of academic accomplishment required in both educational and occupational settings and daily life is this competency. However, especially when learning mathematics, students still have relatively limited skills in addressing complex problems. Including students’ experiences and knowledge from local wisdom-based learning in the learning process can help students develop their ability to solve complicated problems. This study aims to ascertain how the traditional Bugis phinisi notion might help students who struggle with complex mathematical problems. This research employed quantitative techniques, namely a non-equivalent quasi-experimental control group design. Students in class IX of SMP Negeri 1 Kahu in Bone Regency were the research subjects. They were chosen through purposive sampling. The tool employed incorporates sophisticated problem-solving. Gain score tests, homogeneity tests, hypothesis testing, and normality tests were all used in data analysis. According to the findings, the experimental class applied the phinisi notion 88% more frequently than the control class, which did so only 42% of the time. This demonstrates how the idea of a traditional phinisi typical of the Bugis might enhance students’ mathematics ability to solve complex problems.
