The use of concrete artefacts in Geometry Teacher Education for secondary schools

This presentation deals with the use of some concrete geometry artefacts (called Mathematical Machine) for the purpose of drawing curves and realizing geometric transformations within the MMLab-ER project developed by UNIMORE. In the ancient Greece, at the time of Euclid, some concrete artefacts (such as the straightedge and compass) were used in both practical and theoretical geometry. Other artefacts were known in the ancient age and were considered again by the most important European mathematicians as from the 16th century. This presentation reports today’s use of working copies of those instruments (complementary to dynamic geometry system) in secondary school teacher education and development for the purpose of realizing laboratory activities in their own classrooms
