Biological Sciences at the University of Maryland at Shady Grove

The Biological Sciences Program at the University of Maryland offers a degree program at Universities at Shady Grove. The Biological Sciences Program at Shady Grove offers the Advanced Program courses normally taken in the junior and senior years. More information is available at: http://shadygrove.umd.edu/academics/degree-programs/bs-biological-sciences/.

Admission to the Major

The Biological Sciences major is a Limited Enrollment Program. Please see the admission requirements and procedures at: http://lep.umd.edu.

Placement in Courses

Enrollment in BSCI160 & BSCI161 and BSCI170 & BSCI171 requires the eligibility to take MATH120 or MATH140, through direct placement by the Math Placement Exam or completion of MATH113 or MATH115. Note that students who are ready to take MATH135 will have eligibility for MATH120 and thus are eligible to enroll in BSCI160 & BSCI161 and BSCI170 & BSCI171.

Students who earn Advanced Placement or International Baccalaureate Placement credit, which grants equivalency for BSCI160 & BSCI161 and/or BSCI170 & BSCI171 are encouraged not to repeat these courses at UMD but can continue to courses for which BSCI160 & BSCI161 and/or BSCI170 & BSCI171 satisfy prerequisite requirements.

Program Learning Outcomes

  1. Students should have mastered the critical knowledge at each level in the curriculum that is necessary to move on to the next level in the curriculum.
  2. Students should demonstrate an ability to use and apply quantitative methods, especially: interpretation of graphical or tabular data; expression of physical, chemical, or biological process in mathematical form; solving equations to determine the value of physical, chemical, or biological variables.
  3. Students at the lower level should demonstrate an ability to carry out key experimental techniques used in the chemical and life sciences disciplines.
  4. Students at the lower level should have a basic understanding of how to express questions as a hypothesis, how to design a test of a hypothesis, and how to gather and analyze simple data.
  5. Students at the upper level should be able to integrate and apply a relevant body of basic knowledge to the evaluation of existing scientific studies and to design studies to test specific hypotheses that includes design elements typically found in a specific field of the chemical and life sciences.
  6. Students should effectively communicate in writing the processes of science and the results of scientific inquiry.

 MATH140 and MATH141 taken together will fulfill the Mathematics Supporting Courses requirement; however, MATH135 and MATH136 were designed specifically for Biological Sciences majors.  Students who enter the Biological Sciences major after satisfactorily completing MATH140 should take MATH135 instead of MATH141.

Advanced Program Requirements

All Biological Sciences majors must complete an Advanced Program within one of the specialization areas described below.  Students must complete a minimum of 27 credits of Advanced Program study.

For all specialization areas:

  • At least two courses designated as lab at the 300 or 400 level must be taken as part of the Advanced Program.
    • Stand alone lab courses require a C- or better in the pre / co-requisite lecture to count as the upper level Lab requirement
  • Independent study or research credits, including H and L versions, are acceptable up to a maximum of 3 credits overall in the Advanced Program.
  • Multiple semesters in research courses can possibly count for one of the two required lab courses. See your advisor for more details.
  • One credit of Departmental Honors Seminar can count toward the Advanced Program major credits.  Additional Departmental Honors Seminar credits can count as electives toward the 120 credits required for graduation.
  • Special topics courses are approved for specific specialization areas.  See testudo.umd.edu to determine if  a particular special topics course is approved for your specialization area.
  • All specialization areas except General Biology have an Enrichment category. Enrichment allows students to include a maximum of  3 credits from any 300-level or 400-level BSCI, CHEM, or BCHM course in their Advanced Program.  Courses from other departments can be used with permission of advisor. Courses listed in the Advanced Program  can be used if they are not used to satisfy any specific Advance program category. Courses counted as Enrichment do not satisfy the requirement  to take two 300- or 400-level laboratory courses.
