This is quite interesting. I just had a talk with my former
IB maths teacher, and he said that although calculators
with CAS are not allowed on IB exams, if there is a program
written to an originally non-CAS calc (if I recall
correctly exactly the TI-83+ is the most advanced one
allowed) that performs symbolic operations, it cannot be
forbidden either. The only kind of programs that is
forbidden is dummy programs which serve as little
electronic formula booklets. Of course this is IB. But I
don't see any sense in forbiding programs, mostly because
programmers who are smart enough to make them are also
smart enough to hide them well... Then why are programmable
calculators allowed at all anyway? For example, we are not
allowed to use anything for the linear algebra exams, not
even a simple calc that performs only elementary
operations. As regards calculus, we could, but no solution
is accepted without explanation/proper derivation (and
Symbolic wouldn't help with triple integrals either).
Probably teachers should wake up and realise that the
calculators have gone through serious changes and construct
new exercises that fit the new technology better... This is
just a great opportunity to confront them with their
laziness. :)
