In a society becoming ever more mathematical and computerized, the department seeks to provide courses which introduce all students to the ideas of mathematics and computer science. The department also provides advanced courses for those wishing to specialize in one of these areas. We teach these technical concepts in a manner consistent with the liberal arts aim of the College and in a way that encourages the student to use these abilities to serve others.
The purpose of the mathematics curriculum is to present the basic concepts and methods in modern mathematics, to develop the student's ability to think critically using the axiomatic method, and to apply these ideas to other disciplines. This major provides the mathematical background for students preparing for:
- Licensure in secondary education
- Graduate study in a mathematical discipline
- A career in an area using mathematics, such as engineering, economics, statistics, or actuarial science
Students who complete a Mathematics major are granted a Bachelor of Science degree unless they request a Bachelor of Arts degree.
Calculus Readiness Assessment:
Students who plan to enroll in MATH 231 Calculus I must take Wheaton College’s Calculus Readiness Assessment. The Calculus Readiness Assessment (CRA) is a dynamic, online assessment that evaluates students’ strengths in arithmetic, algebra, and other pre-calculus skills. We will allow up to 3 hours for the test but it is typically completed in 60-90 minutes. It is accessible with a Wheaton student login at http://portal.wheaton.edu > New Undergrad Student > New Student Checklist. The assessment has a $15 fee, charged to a credit card.
Students should sign into the CRA area and take a practice test any time after July 1st, but prior to coming to campus. After taking this practice test, the CRA offers specialized learning modules through the student login to “brush up” on skills. We will administer the first official proctored CRA on campus Tuesday before classes. Students should register for MATH 231 and will be told prior to Tuesday the room to which they should report to take the CRA. A score of 65 is required for students to stay enrolled in MATH 231. Should the student need it, a second proctored attempt will be held one week into the semester. Students who earn below a 65 and need calculus for their program are encouraged to enroll in MATH 131 Precalculus.
Computer Science Curriculum
The curriculum in computer science presents the fundamentals of computation—the science underlying the computing technologies that have become so pervasive in contemporary society. This foundation better prepares one to make choices about how those technologies can and should be applied, at the organizational and societal levels, as well as individually. The deeper study required of a computer science major provides experience in the discipline's methods of analysis and problem-solving. Furthermore, experimental work throughout the curriculum allows majors to develop skills in the design, analysis, and development of software systems, and so provides excellent preparation for a computing-related career, as well as for graduate study in computer science or engineering.
Students who complete a Computer Science major are granted a Bachelor of Science degree unless they request a Bachelor of Arts degree.
