The University of Dayton
Last year, Tom began his message with "This will be my last newsletter as Chair."
So, I begin with "This will be my first newsletter as Chair." I began serving a four
year term as Chair on July 1, 2000. I came to the University of Dayton in August 1980.
Jack McCloskey hired me and I have worked only with Jack and Tom as Chairs during my
twenty years here. My goal is to serve this department as well as I've seen it served.
I think it is clear from recent newsletters that the department is undergoing significant
change due to retirements and new hires. It is an exciting time. We are bringing good
people to the department. We are bringing young and enthusiastic teachers who are
developing strong research programs. It is also a reflective time. My long time
colleagues, who have continued and developed the excellent reputation of the department,
are retiring and moving on. Last year, we hired Dr. Atif Abueida who earned his degree
from Auburn University in combinatorics with Chris Rodger as his academic advisor. Before
coming to the USA, Atif had obtained nine years experience in secondary education. We have
also just recently hired Dr. Becky Krakowski who earned her degree from North Carolina
State University in mathematics education. Becky has five years experience in secondary
education. Moreover, the School of Education hired Dr. Janet Herrelko in mathematics
education last year. There are many movements today in mathematics education and the
potential for collaboration is very exciting.
When I began serving my term as Chair, I knew that change would be the norm. I was
thinking mostly in terms of the retirements and the hiring. Since that time, Brother
Raymond Fitz has announced that he will step down as President of the University of Dayton
during the summer of 2002. Brother Ray was President when I came here in 1980. John
Geiger has announced that he will step down as Provost during the summer of 2001. The
administration has decided to replace John Geiger with an acting provost so that a new
president can come on board and put an administration in place. There is very much a
sense of change permeating the entire university environment.
A year ago, Tom wrote that the much anticipated renovation and building of the science
complex would happen. It has stalled briefly; the university has hired an architectural
firm, the HOK Science + Technology Group, to develop a master plan for renovation and new
building and to bring some fresh imagination to the project. This exercise has moved the
anticipated ground breaking from May, 2001 to October, 2001. Planning is currently fast
and furious. The university has already committed to the initial phase of a new building;
recently, the renovation became a high priority university fund raising item and hopes are
high that funds can be raised to complete the renovation phases as well.
We like to hear from you. We want to keep in touch and we have been updating our address
book. We are interested in email addresses as well. We are always interested in
opportunities for our students: positions, summer positions or internships, real applied
mathematics clinics projects, and the like. On behalf of the Department of Mathematics,
I wish you a very special Christmas and a happy new millennium.
Thank you very much for your generous support. We continue to use your support to provide
matching funds to upgrade the department's technology capabilities. The software package,
Maple, is routinely employed in many courses and the introduction of Maple is a part of the
MTH 168 syllabus. The software package, Excel, is routinely used in MTH 128, the first
semester mathematics course taken by School of Business Administration students. The
university now has a PCSAS site license and SAS is routinely used in the statistics courses.
We do not currently deliver any web based courses, but many of our faculty are
experimenting with web based delivery. The demands from technology continually grow and
your support has been instrumental to our ability to deliver mathematics in a modern

19th Biennial Seminar and the Kenneth C. Schraut Memorial Lecture
The Biennial Seminar was held on the afternoon of Saturday, November 4, 2000. The event
included the kickoff to the Kenneth C. Schraut Memorial Lecture and the lecture was
delivered by Dr. Joe Diestel (MTH 64). The title of the lecture was "Sums. Series in
Vector Spaces." The Schraut Lecture is intended to benefit the undergraduate majors.
This lecture began with material that might very well have been presented by Dr. Schraut
in advanced calculus; Joe then developed a colorful history of a theory that has developed
through the twentieth century and Joe left us at the current state of the development of
the theory. The abstract can be found at http://www.udayton.edu/~mathdept/kcs.html.
We were happy to see Dr. Robert Buck (MS 69), Stephen Hodges (MTH 77), Kevin Thomas (MS 76),

We have hired two new faculty members at the assistant professor level beginning
August 2000. They are Atif Abueida and Rebecca Krakowski. Atif earned a Ph.D.
in mathematics from Auburn University in 2000. He pursues research in the area of
combinatorics, with emphasis in graph theory and design theory. Rebecca earned her
Ph.D. in mathematics education from North Carolina State University in May 2000.
She has five years experience in teaching high school mathematics prior to her graduate
work. We expect Rebecca to spend a lot of her time focusing on curriculum development
and revision of mathematics content courses for education majors. Shirley Ober and Les
Steinlage have accepted full-time lecture positions beginning August 2000. Both Shirley
and Les had been on our part-time faculty member list for a long period of time. Shirley
has taught mathematics since 1977, and Les has taught since 1969 at UD.

Tom Gantner is on an administrative sabbatical leave during the fall term of 2000.
Tom is gathering interesting materials for the History of Mathematics course that he will
teach in the Spring 2000. He has been a very active member of the Ohio section of the MAA,
and he will hold the position of the president of the Ohio section of the MAA for the
year 2001. Aparna Higgins is on a sabbatical leave for the full academic year of 2000-2001
and she is at the U. S. Military Academy in West Point, NY. Muhammad Islam will take his
sabbatical for the spring term of 2001. During his sabbatical, Islam plans to continue his
research activities and develop materials on wavelet analysis to be included in MTH 583:
Fourier Analysis course. Inclusion of wavelet analysis, a relatively new and very useful
mathematical tool to scientists and engineers, will enhance the course content of MTH 583.
Carroll Schleppi took a sabbatical leave in the spring term of 2000. She visited primary
grade mathematics classes that exposed her to the application of the NCTM Principles and
Standards. Carroll and Jennifer Hontz have redesigned MTH 204: Math Concepts I to meet
the new NCTM Principles and Standards.
MathSci - Computer Learning Environment
The MathSci Computer Learning Environment supplies the computer needs of students taking
courses in Mathematics and Sciences. It consists of two state-of-the-art computer labs
equipped with Pentium III PCs housed in SH 319 and SH 307. A major asset of the Environment
are the MathSci Fellows, an outstanding group of undergraduates, who support the student
users of the Environment and assist in maintaining its system and software.
SH307 is used equally for teaching and as an open environment. SH319 is used as an open
environment accessible to all students. Student users have access to the campus networks,
the internet, and specialized mathematics and science software (Maple, Matlab, ChemLab,
Interactive Physics, etc.), and general purpose software (MS Office 2000). Numerous
Mathematics and Science instructors courses regularly assign homework that requires their
students to use the MathSci. A large number of upperclass and graduate students depend
upon the mathematics programs available in the MathSci.
The MathSci has formed an alliance with the Office of Learning Assistance to create a
comprehensive learning environment on the third floor of Sherman Hall. In addition to
the computer facilities and the MathSci Fellows, mathematics and science tutors are
available in the classrooms adjacent to the computer facilities. This has become a very
successful Learning Village Initiative making the MathSci an important center for
mathematics and science students.
