Title of presentation:	Ten Years of International Derive Conferences
Abstract:
Everything is going so fast. Mathematical computers programs are so powerful that we may think that it has always been the case. This lecture focusses on how technology has changed the way I teach mathematics, through specific examples. A souvenir from Plymouth, U.K. in 1994: in version 3 of Derive for DOS , implicit 2D plots became available. Could you imagine investigating multiple variable calculus without implicit plots? Many ideas for using Derive as a teaching tool originated from this conference. In Bonn, Germany, 1996, Bert Waits said, about the TI-92: “this machine will change the way we teach mathematics for the next fifteen years!”. This handheld technology allowed computer algebra to be used in the classroom by teachers and students as never before, changing forever the opinion of many mathematicians about graphic calculators. From Gettysburg, USA, 1998, I will recall two independant souvenirs. First, TI-89 and TI-92 Plus Module with Flash technology, giving the possibility to upgrade to future software versions without buying a new calculator. Second: the collaboration between David Parker (Acrospin, Cyclone, DPGraph) and the authors of Derive announced upcoming interesting results. In Liverpool, U.K. in 2000, Derive 5 and its new interface became a reality and spectacular 3D plots capabilities were added. New programming capabilities were introduced, “that have revolutionised the way that programs can be written and displayed in the Derive mathematical environment” as Terence Etchells said. Finally, Vienna, Austria, 2002. I asked the following question: if we use both systems, Derive and the symbolic TI, can the two devices communicate? Some Derivers were concerned with another question: are you organising the next conference? Well, Derive 6 now offers the link I was looking for (and even much more, for example, the ability to show the steps of many simplifications). And without the collaboration of my colleagues Gilles Picard and Kathleen Pineau, this TIME-2004 symposium would not have been possible.
