  • The Ursinus Mathematics and Computer Science Department offers majors in both mathematics and computer science. It also offers minors in computer science, mathematics, statistics, biostatistics and scientific computing. The mathematical sciences make significant contributions to society, engineering, medicine, physics, economics, and politics, and to other fields in the sciences and social sciences. The programs in the Mathematics and Computer Science Department provide students with the tools for analyzing and organizing data, as well as the theoretical underpinnings for modeling important and interesting concepts. These programs provide strong backgrounds in logical reasoning, excellent analytical skills, and the ability to learn new techniques and technologies. All of these attributes are sought after in current and emerging fields and careers.

    For students majoring in mathematics or computer science, the department aims to provide preparation for (1) continued study at the graduate level; or (2) effective teaching in the secondary schools; or (3) employment in business, industry, statistics, computing, or actuarial sciences. For other majors, it seeks to provide the mathematical competence required by the increasing quantitative and analytical emphasis required in many disciplines and careers.

    Computer Science

    Upon graduation students majoring in computer science should be able to:

    • Engineer multiple-component systems that solve real-world problems
    • Program, test and debug in a variety of languages
    • Learn new technologies and tools on their own
    • Design, implement and analyze algorithms and data structures
    • Describe the concept of computability
    • Communicate to technical and non-technical audiences, verbally and in writing
    • Work independently and in groups
    • Articulate the social and ethical issues pertaining to the creation and use of technology

    Requirements for Majors

    A student majoring in computer science is required to take:

Details may be obtained from the Mathematics and Computer Science Department or Education. Those students preparing for secondary teaching should consult the Ursinus College Education Department. There is both a departmental and college minimum GPA requirement for student teaching.
