Introduction

The computer science department offers a major and minor in computer science and collaborates with the mathematics department on a second major. Also, the computer science, business, art and communication departments cooperate to offer a minor in multimedia communication. A degree and minor in business information systems is described in the business department pages.

The computer science program at Goshen College is an academic discipline that provides theoretical and applied perspectives on computer systems, software and hardware. Areas of study include problemsolving techniques, algorithm design and analysis, software design and development, computer hardware, mathematics, human-computer interaction and ethics.

Computer laboratories provide students free access to PC and Macintosh computers. Software available for student use includes various programming language compilers, mathematical and statistical analysis programs, computer-aided drafting software, multimedia software, database programs, spreadsheet programs and word processing programs. Students in upper-level computer science or business information systems courses have access to an advanced computing lab equipped with state-of-the-art PC computers, current software and several servers and networks.

Career and postgraduate opportunities

The liberal-arts context of Goshen's computer science program produces graduates who are prepared for life-long learning in a rapidly changing discipline, who can communicate well and who have a broad understanding of other disciplines – characteristics that employers value highly. Computer science graduates are employed as programmers, analysts, teachers, business owners, project managers, Web developers and network specialists. They work in business, insurance companies, banks, accounting firms, computer consulting agencies, telecommunications firms, higher education institutions and many other settings. Graduates who choose to pursue further education are successful in earning master’s and Ph.D. degrees.

Academic requirements

Students majoring in computer science or computer science and applied mathematics must obtain a grade of C or better in each course counted for the major. Any student taking a computer science course must obtain a grade of C or better in all prerequisites for that course prior to taking the course.

Planning and advising notes

This degree is a rigorous, yet flexible, applied science degree. It offers excellent preparation for a career in applied mathematics, programming in science, industry or engineering. It also offers a strong base for graduate study in computer science or in applied mathematics. The 18 hours of electives permits students to individualize the program. The program is close to a double major in computer science and mathematics and can be completed in four years.

Computer science courses

COSC 200 Programming Techniques 4 (3-4)
An introduction to problem solving, algorithm development and structured programming techniques. Topics include pseudo-code, language syntax and semantics, applets and applications, loop and control constructs, primitive data types, objects, arrays, lists, files, graphical user interfaces, recursion, sorting and searching. Includes three lectures and one 75-minute lab each week. Computer-science majors are required to register for four credit hours. Others may register for three credit hours. In the three-hour option, students complete three-fourths of the course. No programming experience is necessary to take this course; however, either strong algebra skills or some computer programming experience is helpful.

COSC 215 Data Structures & Algorithms 4
A continuation of Programming Techniques. Emphasis is placed on program specifications, data abstraction, information hiding, encapsulation and object-oriented programming. Traversing, sorting and searching algorithms are studied along with an analysis of time-space complexity. Data structures studied include lists, stacks, queues, trees, and graphs. Includes three lectures and one 75-minute closed lab each week. Prerequisite: CoSc 200, (4 credit hours); corequisite: Math 205.
