As DERIVE has been taken off the market and the
TI-92/Voyage 200 generation of the TI-CAS handheld will not be
developed further, we are looking for alternatives to be used in
mathematics' education. Other than the TI-Nspire - which must be
purchased by the schools and the students - there are other interesting
possibilities available for free. wxMaxima is open source, WIRIS for
which the online version is free in Austria and in some other countries
due to general licenses, and GeoGebra, also open sourced with a newly
implemented CAS, are all possible. One of these - or others? - could
fill the gap left by Derive's demise.
In my lecture, I will focus on WIRIS (see WIRIS website) and compare it with DERIVE and other tools. |
