9:00 – 9:45 AM Check–In/Registation and Refreshments (Coffee, Tea, Bagels, Donuts, etc.)
9 AM – 4 PM Book Exhibits
9:50 – 10:55 AM Keynote Speaker: Howard Anton, Drexel University, Philadelphia, PA
Applications Masquerading as Theory - A History Mystery
What is an application? What is theory? How do you tell which is which? We will see that
many of the most important applications are rooted in the historical development of the
function concept. This may well challenge your concept of an application and raise questions
about what you are teaching.  Then...a very scary mystery.
11:00 – 11:55 AM Mathematics of Choice: How did W get elected anyway?
Sandra Monteferrante, Dowling College, Oakdale, NY
A discussion of a number of recent and historical examples of multi-candidate plurality
elections which result in unexpected, perhaps even devastating, outcomes. We show, by
example, how election results may differ depending on the method of counting votes (e.g.
plurality, pairwise comparison, runoff election, Borda count and Approval voting). Properties
of voting methods: Condorcet winner criterion, monotonicity and independence of irrelevant
alternatives are examined along with Arrow’s theorem. Saari’s geometric model and
decomposition theorem are presented and used to compare alternative voting methods.
Finally, voter sincerity and strategic voting are examined in the context of the remarkable
Gibbard and Satterthwaite result.

Building a Multitask Model for Problem Solving in Elementary Algebra
John Tobey, North Shore Community College, Danvers, MA
The majority of elementary algebra courses taught in community colleges in the United States
focus on a few simple cases or types of word problems. However, a broader approach using
a multitask model allows for a greater development of mathematical reasoning skills. If we
examine carefully our assumptions about problem solving in an elementary algebra course,
we may discover some unpleasant realities. Dr. Tobey will present some examples of diverse
types of application problems that can be used to develop a rich multitask approach in
Elementary Algebra.

Mathematics Anxiety
Humberto Cañate, Hostos Community College, Bronx, NY
What is it? Where does it come from? Who suffers from it?
How can we keep it out of the Classrooms?

12 Noon – 1 PM LUNCH
1:05 – 2:00 PM Why Your Computer Modem Needs to Know Trigonometry
Steve Bast, Prince George's Community College, Largo, MD
The end of the 20th century was the beginning of the Information Revolution. This
presentation will show how trigonometric functions are used to describe electronic
data signals.  It will also provide insight to answer the question: "What is 'bandwidth'
and why is it important?"

A Guide Dog in My Classroom
Agnes M. Kalemaris, SUNY Farmingdale, NY
Teaching statistics as a very visual course to a blind student was quite a challenge.  This
presentation will discuss some of the problems, solutions that worked, some techniques
that were not successful,  and testing.

The Next Mathematics Reform Movement
Andrew Grossfield, P.E., College of Aeronautics, Flushing, NY
Over the last few years representatives of the MAA and CRAFTY have approached the
ASEE in order  to promote mathematics reform.  It appears that while the idea of
mathematics reform is attractive, we are not yet ready to implement reform. There can be no
meaningful reform without any mention of the flaws and real problems involved in teaching
mathematics. While we all value and enjoy the ideas of mathematics, math teachers have
never been good at presenting these ideas.  This session will be devoted to a discussion of
the following three papers which have appeared in ASEE Proceedings: 
What is College Algebra? Mathematical Definitions, and Mathematical Forms and Strategies
(participants are encouraged to read these papers prior to attendance, which can be found at:

2:05 – 3:00 PM Map Neighbor Counts
Gary Simon, NYU Stern School of Business, NY
The state of New York has five states as neighbors: Vermont, Massachusetts, Connecticut,
New Jersey, and Pennsylvania. Is there any mathematical regularity to these counts of
neighbors? The following conjecture, slightly rephrased, appeared in a recent article on
spatial analysis: Experience with geographic maps has indicated that, on average, interior
regions will have six neighbors, while regions on the outside border will have four neighbors.
Furthermore, approximately one-third of the regions in any map can be expected to be on
the outside border.  We will provide a simple response to this conjecture. Geographic
maps can be arbitrarily complicated in theory, but the reality is that most maps permit a very
simple answer.

Y2M: Yes to Mathematics
Rochelle S. Robert and Theresa A. Vechiarelli, NCC, Garden City, NY
For the past two years, we have been funded to organize a workshop, on our campus, for
high school girls. The purpose is to get girls excited about mathematics and technology and
other related fields. Come hear our story, how we went about getting funding, assistance
from colleagues and support from the college. We'll even tell you where to buy the great
logo key chains!

3:05 – 4:00 PM The "Minimal Point" for a set of Web Points
Allen Barnes, Queensborough Community College, Bayside, NY
I will start by examining a set of 3 non-collinear points and the point which is the  minimal
total distance from these 3 points. Next I will do the general problem for n points. In this
presentation I will attempt to prove some conjectures regarding the "minimal" point P.

Learning Precalculus and Calculus with the TI-89
Emad Alfar, Nassau Community College, Garden City, NY
In this presentation, participants will learn how to use fundamental features of the TI-89
for teaching Precalculus and Calculus. Examples will be demonstrated and can be used
to enhance student learning and exploration of topics in Precalculus and Calculus.

Introduction to Cryptography
Jack Lubowsky, Nassau Community College, Garden City, NY
A basic introduction to the basic concepts and techniques of cryptography including
Steganography (hidden messages in innocuous documents), Transposition Ciphers
and Substitution Ciphers. Discussion of the use of ciphers to introduce basic probability
in solving cryptograms.
