Mapping Diagrams (forwarded)

Dear NCTM members,

Have you ever used mapping diagrams in your classroom?

A mapping diagram consists of two parallel axes: one for
the domain of a function f, the other for its range. Lines are
drawn from a bunch of points x in the domain to their images
f(x) on the range.

Last year I gave a talk about mapping diagrams at the NCTM
meeting in Washington. I demonstrated software I wrote called
"The Function Visualizer" (public domain) which draws mapping
diagrams (and graphs) and does animation of x --> f(x) for
many points. A number of people expressed interest in using
this software, and said that they would go to our Website
(WWW.MATH.NEU.EDU) to download it. Are you one of them?

If you have used mapping diagrams and/or my software in
your teaching, would you please be kind enough to e-mail me:
BRIDGER@NEU.EDU
and let me know of your experiences? This will be used in a
paper that we (my wife Maxine and I) are writing for the NCTM.

--- Thanks for your help,

Mark Bridger
