Some Reflections About the Impact of Computer Algebra Systems in the Ordering
   of the Curricula of Mathematics

The contents of a curriculum can be ordered w.r.t. different criteria, but for
many years Mathematics have been taught everywhere following the same
``general'' pattern. We are designing, implementing and testing a set of
classroom experiences in order to try to prove that the use of Computer Algebra
Systems (CASs) makes it possible to change the order of topics. Also a CAS can
override the need of a detailed knowledge of algorithms in some cases. These
reflections are extensions of well-known theories (scaffolding, black and white
boxes...). The experiences already carried out confirm our thesis.
