Requirements for the major


The requirements for the degree of Bachelor of Science with a major in Biology (a minimum of 51 credit hours) are:

I. A Minimum of 34 Credit Hours of Biology Distributed as Follows:


B. Area B:


Courses listed as Area C Biology offerings (such as Independent Study, Internships, Senior Seminar and Conservation Biology) in the Courses of Study Bulletin may not substitute for the courses listed immediately below. Students complete one of the following concentrations.

1. Ecology and Evolution.

Four courses from the following list:

3. Integrative Biology.

Four courses selected in consultation with the student’s advisor from the lists in 1 and 2.

Note:

*See the Biochemistry and Molecular Biology Program for the Bachelor of Science in Biochemistry and Molecular Biology

C.


8 additional hours in biology at the 2000 level or higher, four of which must be another Area B biology course of a biology adjacent course at the 3000 or 4000 level approved by the department chair.

II. A Minimum of 17 Credit Hours of Chemistry and Mathematics, Distributed as Follows:


III. University Requirements


Completion of all other required elements of the Pathways curriculum and at least 120 credit hours.

Teacher Certification in Biology


Students majoring in biology can receive certification to teach biology in grades 4-8 and grades 8-12. In order to receive certification, students major in biology, complete 11-14 undergraduate hours of education coursework, and complete the Master of Arts in Teaching graduate program at Trinity. After this course of study, students would have a B.S. in Biology, a master’s in teaching, and teacher certification in Texas. For more information and specific requirements, see the Education Department’s program description in the course catalogue.

Admission to Major


Guidelines for Acceptance of Majors


Full acceptance in the major is granted if the following requirements are met at the time of application:

  1. Completion of BIOL 1311 , BIOL 1111 , BIOL 2312 , and BIOL 2112  with grades of C- or better in each class.
  2. Completion of CHEM 1311 , CHEM 1312 , and CHEM 1112  with grades of C- or better in each class.
  3. An overall grade point average of at least 2.0.

Students who do not meet the above criteria may be granted provisional acceptance if it is judged that there is a reasonable expectation they can complete the degree program.

A student may not earn a major in Biology and another major in Biochemistry and Molecular Biology or in Neuroscience.

Honors Program


Honors in Biology


Biology majors are eligible to enroll in the Honors Program if they satisfy the University requirements that are described elsewhere in this bulletin. During their junior year, honors candidates should identify a faculty mentor and meet with the Department Chair. Completion of the Honors Program includes six hours of research courses (BIOL 4398  and BIOL 4399 ). Honors candidates must submit to the Department Chair a written proposal to graduate with Honors in Biology prior to starting BIOL 4398 . The decision to confer or not to confer honors will be made by the departmental faculty and will be based on the quality of the written thesis and the oral presentation of that thesis.
