Frattart: Revisiting Fractal Geometry in Physics and Mathematics Education through Interdisciplinary Co-Design

The FRATTART Project investigates how fractal geometry can transform students’and teachers’con- ceptions of measurement, dimension, and the relationships among mathematics, nature, and art. Using a three-phase Design-Based Research approach in an art-focused upper-secondary school, researchers and teachers co-designed and implemented interdisciplinary activities comparing Eu- clidean and fractal measurement, centred on scale dependence and fractal dimension. Data from questionnaires, observations, recordings, and students’artworks were analysed in a master’s thesis. Findings highlight shifts in students’understanding of dimension and complexity and support teach- ers’development of inquiry-based, interdisciplinary practices that connect mathematical modelling, physical phenomena, and artistic creation.
