The Department of Biology introduces biology majors and other students to the concepts and role of biology as an integrative science, helping them to discover and interpret the characteristics of nature as part of Godís creation. Biology majors are expected to comprehend and integrate biological principles at the molecular, cellular, organismal, population, and ecosystem levels in order to be prepared to teach, enter the health professions, pursue graduate work, or enter the biotechnology industry. Biology majors and students who take the general education component of the biology curriculum are expected to understand the concepts and processes of biology as a scientific discipline. The Department of Biology aids students in the development of both Christian and biological perspectives for their careers and practices as stewards of Godís creation.
Students who complete a Biology major are granted a Bachelor of Science degree unless they request a Bachelor of Arts degree.
Requirements for a major are 36 hours in Biology including , , , , , , and 14 hours of electives including at least one course from each of three course clusters: Organization of Life, Diversity of Life, and Processes of Life. The same course may not be used to meet the requirements for more than one cluster. A biology major is required to develop a sound understanding of chemical processes as well as biological ones, and this requirement is fulfilled in one of two ways: (1) by completion of , , and (2) by completion of , , , and an additional course in science.
Students interested in health professions may take the following courses among their 14 hours of electives: , , , and . Students interested in medical school must also take and .
Requirements for a major with a biotechnology emphasis are , and and 14 hours of electives that must include , , and . Chemistry requirements are the same as those for the biology major. Additional recommended courses are , , and .
The biology faculty members maintain ongoing research projects and encourage students to participate in their collaborative research groups. Research experiences are designed to provide students with opportunities to play a significant role in the processes of scientific investigation with the goal of contributing to current scientific knowledge. Active participation in these experiences develops the student's understanding of the processes and limitations of science, encourages critical thinking skills, and improves their ability to better evaluate published scientific reports. Students who are interested in participating in research should contact the Biology Department office or individual faculty members.
An honors program in this department requires at least six hours of biological research credit or its equivalent, an overall GPA of 3.5 and a biology GPA of 3.7 (supporting courses are also considered in the biology GPA). The research requirement can be met by (1) six credits in (2) a research experience off campus* or as a Summer Researcher at Wheaton, or (3) a combination of (1) and (2). In any case, communication of results in a publishable paper (in preparation, in review, or in press) or communication of results at a scientific meeting [National Conferences on Undergraduate Research (NCUR), Council on Undergraduate Research (CUR), Associated Colleges of the Chicago Area (ACCA), or any professional society meeting)] or an equivalent professional accomplishment as determined by the Department of Biology is also required. Participation in departmental and college activities also is considered in awarding of departmental honors. An application for honors consideration in biology can be obtained from the departmental office. Application for honors must be made by the second Friday in February of the studentís senior year or by the second Friday in October for a December graduation.
*Approval of the off-campus research must be granted by the department prior to the experience in order to receivecredit or for inclusion of the experience as a consideration for honors.
Requirements for teacher certification by the State of Illinois in biology may be met by completing 26 hours of courses in biology consisting of , and , and by completing 24 hours of supporting courses consisting of , , , , , or , and . and may be substituted for and .
A Master of Arts in Teaching (MAT) program is available with a Biology major. A combined Bachelorís/MAT program may be completed in six years and one summer. See the Education section of this catalog for further details.
Cross-referenced courses cannot be used for the minor in Biology and cannot be counted toward a Biology major if they are included in the major or minor program of another department.
Students may register for biology elective credit in cooperative programs such as courses provided by thethe or the Shedd Aquarium.
