International Congres on Mathematics Education (ICME) location:Kopenhagen date:7-10 July 2004
Solids of revolution are well-known study objects in secondary school mathematics. Generally, they appear among the applications of integral calculus and they are generated by the revolution of a plane curve or figure around an axis in the same plane. In this workshop, participants will revolve entire solids instead of plane curves and they will describe the generated solids. These problems are designed for upper secondary school pupils and future mathematics teachers. New objects will emerge out of this investigation, a historical sketch of which will lead to a Belgian three-dimensional proof, of 1826, of some properties of conic sections.
