Biological Sciences

Faculty/Staff

Arthur Schwarz, Chair; Arthur Chadwick, Amy McHenry, Peter McHenry, Jared Wood

Aims of the Department

The mission of the Department of Biological Sciences is to encourage thoughtful investigation of living systems.

Student Learning Outcomes

Biological Sciences graduates will be able to:

  • Use scientific processes (observe nature, pose problems, generate and test hypotheses, design experiments, interpret and evaluate data, and determine how to follow up on findings), especially involving quantitative reasoning and analysis.
  • Communicate effectively with people both in biology as well in other disciplines through written, visual, and oral methods.
  • Evaluate the social, ethical, and moral implications of biological research and how science impacts their faith.

Programs

The department offers a Bachelor of Arts and a Bachelor of Science degree in biology. The B.A. degree requires 36 semester hours in biology and includes a foreign language component. The B.S. degree requires 40 semester hours in biology and emphasizes course work in biology and the sciences. Required cognate courses are specified for each degree. Southwestern Adventist University requires 40 hours of upper division credit for graduation; it is the responsibility of the student to meet that requirement through electives and general education requirements.  The program has flexibility to allow students the choice of elective biology courses of special interest beyond the basic requirements listed below.
