College of Arts & Sciences Catalog
Computer Science
The computer science major is a four-year program designed to acquaint the student with this rapidly expanding, contemporary subject. The computer science program has been carefully constructed to build upon the broad liberal arts and biblical studies courses that are part of every student’s program at Bethel. In today’s complex world, communication skills and historical perspectives are of critical importance to computer professionals.
Student access to computing hardware is a major emphasis in the program. Hands-on experiences are provided throughout the program, beginning with the first course in the sequence. Students are also encouraged to gain practical work experience while they are enrolled in the program. The department supervises internships at local companies, subject to faculty availability. There is also opportunity for employment in the Information Technology Services Computing Center.
