Many thanks for this reply.
I have been working on a computer algebra based computer aided assessment
system for some years we have just moved to sourceforge: see
http://sourceforge.net/projects/aimmath/
This system is built on Maple, and my motivation for joining the Maxima
group is to explore the possibility of re-writing AIM to use Maxima
instead. This will make the entire package open source, and hence
available to a much wider community of mathematics educators.
I'd very much appreciate advice from people on this list as to the
feasibility of doing this. We have a lot of experience in writing and
using the AIM system: computer algebra marking of mathematics is going to
be a very exciting new area in mathematics education in the very near
future. It would be very satisfying if the cutting edge system was
completely open source, and not (as it currently the case with
AIM) reliant on proprietary software.
One option is to re-write the system in Java, with the option to call to
either Maple or Maxima, depending on which system the user can
afford. Much effort has been expended in developing learning materials
with Maple code in, including sophisticated feedback based on a properties
of a student's answer. It would be a real shame to loose this if we
re-write. For an example of this see
http://www.mat.bham.ac.uk/C.J.Sangwin/AIM/SubstitutionFeedback1.png
Does such a project for Maxima already exist (I've been on this list
for only two weeks)? How much support would there be for such a project?
