STEM program
Program Description
The bachelor of arts degree is designed for students who seek a broad education in biology. This degree is suitable preparation for a diverse range of careers including health science, science education and ecology-related fields.
Students can earn the BA in biology alone, or with one of four emphases: biodiversity, bioinformatics, education or health science.
Learning Outcomes
Students who complete any of the bachelor of arts in biology will be able to:
- Describe biological, chemical and physical principles as they relate to the natural world in writings and presentations to a diverse audience.
- Place scientific knowledge into an ethical context, including how biology can contribute to the resolution of ethical, social and environmental issues around the globe.
- Apply the methods of scientific inquiry, including observation, hypothesis testing, data collection and analysis for laboratory research.
Degree Requirements
For information on the general requirements for a degree, see Baccalaureate Degree Requirements under the Academic Policies and Information section of this catalog.
- 54 credit hours core coursework
- 12 additional credit hours in BIOL, CHEM or PHYS at the 2000+ level
or Courses specific to the selected emphasis - Applicable University Global Citizenship Program hours, with accommodations for the biology BA
