Department of Mathematics and Computer Studies
The study of mathematics affords excellent training in rigorous deductive logic and familiarizes the student with results and techniques widely applied in science and industry. Students who major or minor in math are prepared for many different experiences after graduation. Some pursue graduate work in mathematics or an allied field. Other students obtain jobs with various industrial and research-oriented firms.
"You're a mathematics major? So, what are you going to do with it?"
The answer to this question is, "Whatever I want!" When you major in mathematics you are prepared to enter many different fields after graduation. One of our guiding philosophies is that if you couple your major (or minor) in mathematics with another major (or minor), your possibilities are endless. Some recent mathematics majors and minors at Salem have also completed undergraduate work in:
|Accounting||Arts Management||Biology||Business Administration|
Our students have entered graduate and professional programs in mathematics, statistics, biometry, biology, chemistry, epidemiology, law, medicine, dentistry, economics, econometrics, accounting, religion, secondary education, educational statistics, public policy, nursing, secondary school administration, civil engineering, environmental engineering, and mathematics education. Our graduates have also found employment opportunities in a wide variety of fields after graduating from Salem, including public health, biostatistics, aviation consulting, fund raising, accounting, banking, financial planning, economics research, elementary, middle and secondary school teaching, and college and university faculty positions. We have alumnae who own their own businesses, who are well-respected artists, who have chaired boards, who are college professors, and who are award winning high school teachers.
Opportunities for internships and summer research experiences are available, both locally, nationally and internationally, and many of our students take advantage of study-abroad opportunities in places such as Hungary, Japan, Germany, Australia, Hong Kong, Greece, and the United Kingdom.
On-campus, mathematics majors and minors are active and visible participants in the Women in Science and Mathematics Program (WISMP), the Celebration of Academic Excellence, the QUEST Program, student life and student government.
Mathematics Placement and Academic Support
All undergraduate students entering Salem College take a Mathematics Placement Examination in order for the department to properly guide each student to the appropriate mathematics courses that satisfy Salem Signature requirements or that satisfy the requirements for her intended major. Traditional-aged students should click here for more information and Fleer Center students should click here for information and instructions. Students are encouraged to enroll in the course in which they are placed as early as possible during their Salem career so that they may benefit the most from the quantitative experience.
Academic support services are offered to students through the Office of Academic Support and through the QUEST Program for quantitative enrichment, science and technology. The QUEST Center offers on-line resources and in-person tutoring for free to all Salem College students. The mathematics department also employs qualified work-study students whenever possible to provide free tutoring in many first- and second-year level courses.
Why Take More Mathematics than is Required by Your Major or by the Salem Signature General Education Program?
Research continues to support the notion that women who take more mathematics courses in high school and in college experience a positive impact on future earnings. (See: Rose, Betz, Math Matters: The Link Between High School Curriculum, College Graduation and Earnings, 2001.) So, while you may only be required to take a single mathematics course for your major or for General Education purposes, we strongly encourage you to consider taking at least one additional course from our department in order to maximize your earnings potential, strengthen your applications for graduate or professional school, and increase opportunities for internships while a student at Salem College. Rest assured, we will help you and your advisor choose any and all mathematics courses which would be most beneficial to you based on your past mathematical experiences and your academic or career goals.
The mathematics faculty are active, engaged mathematicians that regularly participate in and present at national and international conferences and are committed to the undergraduate education of each Salem student, regardless of the student's major. With nearly 70 years of combined teaching experience at a variety of levels, and numerous teaching awards between them, you are assured a personal, professional, and individual experience, no matter how many mathematics courses you choose to pursue.
Professor Debbie Harrell (email@example.com), chair, received her BS in mathematics from Wake Forest University and her MS in applied mathematics from North Carolina State University. She teaches all levels of mathematics at Salem, and has a love for the history of mathematics and the Fibonacci numbers, and is dedicated to the use of technology in the teaching and learning of mathematics. She is a two-time recipient of the Omicron Delta Kappa (ODK) Teacher of the Year award at Salem College and has received the HA Pfohl Award at Salem for her service and loyalty to the College and for her excellence in teaching.

The department offers both a Bachelor of Arts and a Bachelor of Science degrees with a major in mathematics, as well as a minor in mathematics, a minor in actuarial science, and a minor in statistics, each of which provides you with the opportunity for in-depth study and prepares you for a wide range of careers and post-graduate study. In consultation with the faculty in the department, you will choose appropriate elective courses and other on- or off-campus opportunities that complement your interests and prepare you for the goals you have set for your future. Our courses are taught in classrooms equipped with relevant technology, including computer algebra systems, object-oriented programming capability, dynamic geometry software, and state-of-the-art statistical computing environments.
When you graduate with a major or minor in mathematics, a minor in actuarial science or statistics, you will have the quantitative and technological skills necessary to go right into the workforce or right into graduate or professional school. You will be well-equipped to communicate mathematical concepts and ideas, to use appropriate technological tools, and to succeed in whatever goals you have set for yourself.
