Bachelor of Science - Mathematics

Degree Overview

Mathematics, literally knowledge, study, learning, investigates the logic of structure, quantity, and change, developing concepts that provide the foundations and landscape of many fields of knowledge. Mathematicians engage in determining exact explanations for the truth of subtle and complex propositions. Mathematical ideas, studies, and findings range from abstract and theoretical to applied and practical. Applied mathematics and statistics lend effectiveness to study of many fields such as sciences, engineering, economics, finance, and risk management.

The mathematics program is flexible and allows students to tailor their education in one of four options:

  • Mathematics
  • Mathematics - Teacher Education
  • Data Science and Statistics
  • Actuarial Science

View the specific degree requirements and course descriptions in the Undergraduate Catalog.

  • Students can individualize their plan to prepare for careers in Education, Data Science and Statistics, Actuarial Science, or prepare for Graduate School.
  • The Integrated Degree Program allows qualifying students the opportunity to earn a baccalaureate and master’s degree in just five years saving time and money.
  • Faculty are actively engaged in research and are available for Independent Study courses, Honors projects, and Undergraduate Research Day projects.
  • Small upper division class sizes allow one-on-one interactions with the professors.
Integrated Bachelor/Master of Science

The integrated baccalaureate and master’s degree program provides an opportunity for academically strong undergraduate Mathematics majors to complete both the bachelor’s and master’s degrees in five years. The program is designed to provide an accelerated alternative to traditional programs by preparing students who would pursue a career in business, industry, or government, as well as to train mathematicians who would pursue further study toward a doctoral degree in mathematics. View the Graduate Catalog for program details.

Students are exposed to a rich combination of mathematical areas in pure and applied mathematics. Additionally, students are given an opportunity to deepen their understanding in areas complementing mathematics major, such as physics, chemistry, biology, computer science, or economics. This option is well suited for students interested in a graduate degree in mathematics or statistics as well as those seeking mathematics related jobs in non-academic settings.

This option includes a sequence of three directed elective courses aimed at developing an in depth understanding in a single focus area. The focus areas include, but are not limited to 1) General Mathematics, 2) Applied Mathematics and Statistics 3) Natural Sciences, Computer Science, or Economics.

General Mathematics Focus

This focus is geared toward graduate studies in mathematics. Focus area courses include any 300-400 level mathematics courses that encourage the development of a rigorous mathematics foundation for graduate education.

Applied Mathematics and Statistics Focus

These two focus areas cover the conventional applied mathematics and statistic concentrations and are for students who seek graduate degrees in applied mathematics/statistics or research related careers. Most jobs entitled mathematician or statistician outside of academics are application driven, and many such jobs require graduate education. Option A, accomplished through either of these two focus areas covers almost all the necessary foundation for related graduate education to become a mathematician or statistician. Focus courses are typically selected from mathematics, statistics, or decision science.

Natural Science, Computer Science, or Economics

It is practical for a math major to develop a base knowledge in another field related to mathematics. Option A provides a rich mathematical training for any science major. In fact, this focus encourages double majoring in Mathematics. Related minor courses will be guided to complete the prerequisite requirements for each focus.

Mathematics - Teacher Education

Students in this comprehensive major earn a degree in mathematics and obtain an Illinois Professional Educator License to teach mathematics in grades 9-12. The program produces teachers who can find employment and share their knowledge and appreciation of mathematics with the youth of Illinois and other states. Some students choose to continue on to graduate school and then may teach mathematics at the community college, college, or university level. In all cases, the graduates of this program have the opportunity to impact and inspire future generations by exposing them to the beauty and power of mathematics.

Students are well trained in a variety of fundamental mathematical areas. In addition to studying pure and applied mathematics and statistics, students in this option obtain professional skills in education courses as well as student teaching. Our program is designed to uphold the highest standards of State of Illinois educational requirements. As a result, students that obtained B. S. degree with our department pass the Illinois Professional Educator License test at the rate of 100%.

Data Science and Statistics

Students are rigorously trained in mathematics, statistics, decision and computer sciences. Data Science is one of the most attractive options that combines data analysis with mathematics. If you are seeking a career in computational mathematics or data science this option is for you.

Data Science is a rapidly growing interdisciplinary field, exploiting both theory and experimentation in data analysis. It is now clearly recognized as a distinct intellectual and technological discipline lying at the intersection of applied mathematics, statistics, and computer science. Data Science is, in part, data management and computationally-intensive data analysis based on scientific computing methods. There has been a significant growth in the volume of scientific data from experiments and observations, large-scale simulations, and large networks of sensors. Incorporating vast amounts of data into scientific applications often relies on mathematics, computer science, and statistics techniques, which have become essential tools in computational and data sciences.

Our Data Science and Statistics Option provides the mathematics and computer science foundation to professional development, as well as training in Probability and Statistics, Modeling and Simulations, Numerical methods, Data Mining, predictive Analytics, Database Applications and Management, basics of Experimental Design.
