MATHEMATICA Activities Group
The purpose of this group is to make contacts using MATHEMATICA in teaching
(including high schools). The interest is not in the use of software
specifically designed for educational use (e.g. Geometer's Sketchpad,
to note an impressive example) but in "general purpose software for
doing mathematics" such as MAPLE, MATHEMATICA, or MATLAB, where effort
is required in adapting the software to educational purposes. And,
while these three softwares have similar capabilities, the purpose of
this group is to concentrate on one software for simplicity.
(Other softwares, other groups.)
MATHEMATICA is extremely powerful software originally intended to support
computation for research in mathematics and applied mathematics and for
industrial mathematics. It has capabilities far beyond the level needed
in high school or undergraduate courses. All the better: experience
students gain with the software has substantial potential for use in
higher classes, including graduate school, and outside the classroom.
There are three typical levels of use:
 For transparencies or demonstrations. Here the software is used by
the instructor alone to support lecture activities.
 For "canned" exercises available to the students. These might be
already available or prepared by the instructor. The students might set
parameters or other controls and experiment with the results but would not
actually "learn the software".
 For student use in homework and lab exercises and in projects. Here
the students must actually learn commands, syntax, and so forth and use
that knowledge in an active manner to solve problems.
Comments:
 An instructor can devise his/her own examples and exercises, allowing
more focused attention on concepts and more tiein with course material
than might be feasible with massmarket material.
 Multistep problems can be assigned without the worry that half the
class will get the algebra wrong on the first step. Indeed, having
students check their work in various ways at various steps can be used to
practice and reinforce concepts.
 Projects can be assigned involving actual applications or similar
levels of complexity. In particular, projects could be set up to overlap
between math courses and science/engineering courses and involve real data.
(I find this interdisciplinary aspect extremely intriguing.)
 Students get experience with "realworld" software.
 Although students do not get direct reinforcement of the mechanics of
hand calculations, they can get significant practice in manipulating
mathematical expressions. Symbolic calculations can involve considerable
juggling to get an expression in an informative or useful form, and the use
of software forces them to think about this process in a focused, rather
than haphazard, manner.
