COMPUTER SCIENCE
Faculty: Mr. DeJongh, Mr. Dershem, Mr. Jipping (Chairperson), Mr. McFall.

Computer science is a dynamically growing discipline. In recognition of this fact, the Department of Computer Science is committed to providing students with a program that includes the basic fundamentals of the field and allows students the flexibility to pursue in depth many of the diverse areas into which computer science is expanding. This is accomplished by providing both instruction in the theoretical principles and experience with a diverse collection of modem hardware and software technologies. The faculty and students of the department cooperatively carry out research in the areas of web technologies, algorithm animation, software engineering, networking, and handheld computing.

COMPUTER RESOURCES --The computing facilities at Hope College give the student an opportunity to obtain a rich variety of experiences. The Department of Computer Science supports a network of 35 powerful Unix workstations for classroom and research work. These systems provide a window-based user interface, high-resolution graphics, a parallel processing environment, and high-speed computation. They are located in a general student laboratory, a research laboratory, and a unique laboratory-classroom combination. This laboratory-classroom contains 12 student workstations and is used for all computer science classes to incorporate hands-on laboratory experiences. The departmental network is also accessible from residence halls via direct network connection. Many personal computers are available for use by students and faculty, and are located throughout the campus in dorms and labs. All students have access to electronic mail and the Internet.

THE COMPUTER SCIENCE MAJOR --The department offers major programs that emphasize problem solving and communication skills and allow students the flexibility to design programs suitable for their interests and goals. Each student's major program, designed by the student and a departmental advisor, includes a core of computer science courses, a strong component of courses in some field to which computer science can be applied and a senior project seminar involving research or software development under the supervision of a member of the Hope College faculty. By following an appropriate major program, students may prepare themselves for graduate study in computer science or computer science careers involving applications programming, systems programming, systems analysis, computer design, teaching, or software engineering.

COMPUTER SCIENCE MAJOR REQUIREMENTS --The requirement for an A.B. degree in Computer Science is a plan of study approved by the department that includes at least 32 credits in Computer Science courses, not including 140.
