I think that is an absolutely wonderful decision. I wish I was of
student age (and spoke Polish!) to avail myself of it, and the
associated maths courses.

I think mathematicians, and more particularly, users of maths, have a
range of styles of thought, and the every concrete approach, which
Mathematica encourages, would certainly have appealed to me.

To give a specific example, I remember trying to learn about group
theory. For a long time, groups seemed somehow vague to me. I learned
the axioms of what counted as a group, and thought "Yeah well - so
what!". I learned (or tried to learn) assorted other definitions, such
as "normal subgroup", and of course, I looked at various tiny examples
of groups. However, what I really needed was software which would let me
make examples that were big enough to begin to see why all those
definitions were any use - software that let me explore. I am the sort
of person who finds it hard to learn something that doesn't seem any use
- even if I know that everyone says it really will be useful once I get
to understand it!

As to the issue of alternative CAS software, I did chemistry, and nobody
worried about the fact that all our NMR machines were Varian, or that
the infra red machines were made by Perkin Elmer, or that we learned to
program the type of computer owned by the university - a technical
university course inevitably focuses its students on certain products.

You say the focus will be on graphics rather than symbolic computation,
but I must say, I think symbolic computation is the more exciting part -
because it opens up entirely new possibilities.

Take symbolic integration as an example. I know there are those who
would say students should be told to solve all their integrals with
Mathematica (and take a calculator to add their bills when they shop)
but I am not thinking that way. It is easy to make a construct in
Mathematica that displays like an integral, but doesn't evaluate. Using
this, students could explore strategies such as change of variable -
simply using pattern replacement and simplification. Mathematica would
be contributing no skills that the students didn't already know - simply
adding some muscle to help explore more substantial problems.

I wish you success!
