The document summarizes a conference called LIMACON 2003 that the author attended. It discusses three presentations: the first on using technology in calculus classes, the second on using technology to teach linear and non-linear regression analysis, and the third presented by the author on solving differential equations graphically, numerically, analytically and verbally. The author recommends that mathematics classrooms be remodeled to have permanent projection devices installed in order to better utilize graphing calculators and technology in teaching.

RE: Limaçon 2003
CC: BSHS Mathematics Department
Background:
Every year in March, the Long Island Math Conference is held at
SUNY Old Westbury. LIMACON 2003 attracted presenters and teachers
from all over the globe. The conference covers topics in teaching mathematics
and computer science from K-College. I have been attending since 1990 and
presenting since 2002.
Observations:
My first session was presented by Evanthia Basias. Ms. Basias
teaches AP Calculus at Brooklyn Technical High School. Her presentation
was about using technology in the mathematics classroom in general and in
the calculus classes in particular.
The second session was presented by Jerry Resnick, recently retired
Mathematics Department Chairperson at Roslyn High School. His
discussion, demonstrated the use of technology when teaching about linear
and non-linear regression analysis.
I was invited to present for the third session. I spoke about solving
Differential Equations Graphically, Numerically, Analytically and Verbally.
This is a new topic for AP Calculus AB teachers as it will be tested on the
2004 AP exam for the first time. I have taught this topic for my AP Calculus
BC students for several years now.
Recommendations:
Now that most every Mathematics class uses the TI-83 or TI-89
graphing calculator, each Mathematics classroom should be remodeled.
Having to bring in and set up a projector at the beginning of each period
wastes too much of the teacher’s time between classes and instructional time
during class. I would recommend that each Mathematics classroom be
refitted with at least one marker board for projection. The TI projectors show
up best on a white background. A pull-down screen is not preferred, however,
as we would like to write on the graphs. Also, there should be a permanent
projection device in each teacher’s desk. This is how I teach math at Nassau
Community College. The projector is recessed into the teacher’s desk and
ready to project on the marker board.
