The biology department offers a balanced curriculum suited to the diverse needs of our students. Our curriculum embraces the breadth of the discipline, and values both classical and modern approaches of biological inquiry. We seek to furnish students with current knowledge and technical skills, and we strive to provide opportunities for intensive studies using this expertise. Students may choose between a major or minor preparatory to specific career programs. The major sequence prepares students for graduate studies in the biological sciences and science education, and for entry into professional schools including medicine, dentistry and veterinary medicine. The major and minor sequences both provide a suitable background for career areas such as business, industry, law and government service. Non-major courses are offered for students in the arts, humanities, social sciences and allied health professions.
Courses embody current biological principles and laboratory techniques. We occupy two buildings furnished with extensive laboratory equipment including transmission and scanning electron microscopes, high-pressure liquid and gas-liquid chromatographs, DNA sequencer, ultra and high speed refrigerated centrifuges, walk-in environmental, metabolic and cold chambers, bright field, dark field, fluorescence and inverted microscopes fitted with video and digital cameras, and a variety of spectrophotometers. The rural setting of the two campuses is ideal for field studies providing easy access to a variety of natural habitats, including prairie, savanna, wetlands, coniferous and deciduous forest, ponds and several lakes. In addition, a greenhouse, weather station, herbarium, arboretum, natural history museum, and extensive collections of insects, birds and mammals provide excellent facilities for ecological and other field-related research.
The Biology Department has adopted a multifaceted approach to assessing the effectiveness of its curriculum. In addition to standard measures, such as monitoring performance on tests, the Biology Department will administer and requires:
- All students in 121 take a pre- and post- test of basic information that they would be expected to gain from taking this course.
- Seniors take a comprehensive exam during the spring semester.
- Students enrolled in an upper division biology course during the spring semester take the “Annual Biology Department Assessment Survey”.
- The department will also survey alumni at five-year intervals.
Major (45 credits)
121, 221 and 222 as a basic introductory sequence; 1 credit of 348; and a minimum of five biology courses at the 300 level, totaling at least 20 credits, chosen in consultation with an advisor in the department. Beginning with the class of 2011, all biology majors will be required to complete a 4-credit senior capstone course.
For the biology major, the lower-division courses are designed to provide a broad background in basic biological concepts. The upper-division requirements are designed to offer a more in depth exposure to the principal disciplines within biology and permit some specialization along lines of individual interest. Biology majors are encouraged to attend departmental seminars featuring presentations by outside speakers and to participate in independent research in the field or lab. Seminar attendance is required for students enrolled in BIOL 348.
Students may apply only two courses from the following toward the major: 323, 325, 326.
The close interrelationship of biology to other disciplines requires that majors complete two courses in chemistry (CHEM 123 and 234) and one course in mathematics (MATH 118, 119, or 124).
Strongly recommended are courses in organic chemistry (CHEM 235 and 236) and physics (PHYS 105 and 106). Students intending to continue in graduate or professional school should design appropriate programs of study with the assistance of a biology department advisor.
