I work primarily with the TI-84 Plus graphing calculators.
My philosophical position is that the graphing calculator
is an educational tool that should be used, when applicable,
to enhance the learning of mathematics, but should
not be used in any way that replaces the student's
role in learning or critical thinking..
I have developed online tutorials for using the TI-83 or
TI-84 within a College Algebra, Trigonometry, or Precalculus
course (all available on CD-ROM also). If you have one of
these models, I encourage you to investigate the tutorials.
They should be especially helpful to those having limited
experience with the TI-83/TI-84 or with graphing calculators
I have also written some programs that I use in various math
courses. Choose a link (at left) for a list of programs available
for the model shown. These programs can be downloaded onto
your calculator using the TI-Connect software and cable. TI-Connect
can be downloaded at no cost from the Texas
Instruments web site, and cables can be purchased in many
stores (Staples, Office Depot, etc). For instructions on how
to download programs, click on the appropriate link (at left).
