Geometric modelling inspired by Da Vinci: Shaping and adding movement using technology and physical resources
Résumé
We report on the experience gathered in a study using a geometric modelling approach based on dynamic geometry systems complemented by physical modelling. Our strategy intends to strengthen the interconnections between the current trends in Science, Technology, Engineering, Art and Mathematics Education. To help students to better understand how certain physical mechanisms work, some da Vinci machine prototypes were reconstructed and used as a starting point for this study. Building upon previous experience, our work currently concentrates on the analysis of connecting physical and digital resources and on how they contribute to students' creative thinking and problem-solving. We discuss the concept of geometric modelling, focusing on spatial thinking, joints and their movements. Further, we present some new manipulatives that are being tested together with digital applets and discussions from this practice.
