Course DescriptionLecture, recitation, and laboratory cover: bacterial identification, morphology, metabolism and genetics; bacterial, viral, and parasitic relationships with human health and disease; and basic immunology. Laboratory stresses aseptic technique, bacterial identification and physiology using a variety of media, culturing techniques, and staining techniques. Recommend BI 231. Prerequisites: BI 112 or (BI 211 and BI 212) and their prerequisite requirements. Audit available.
Addendum to Course Description
This microbiology course is required for Applied Science in Nursing and Applied Science in Dental Associate degrees, and recommended for students entering general biology, microbiology, molecular biology and Bachelors degree programs. Students should check with a counselor or microbiology instructor to determine specific programs for which it is recommended or required.
A lecture format is used to introduce the students to the subject matter. The recitation is a dialogue format for student questions. In the laboratory section of the course the students will perform pertinent experiments working with live bacterial cultures.
To clarify the teaching of evolution and its place in the classroom, the Portland Community College Biology Departments stand by the following statements about what is science and how the theory of evolution is the major organizing theory in the discipline of the biological sciences.
- Science is a fundamentally non-dogmatic and self-correcting investigatory process. In science, a theory is neither guess, dogma, nor myth. The theories developed through scientific investigation are not decided in advance, but can be and often are, modified and revised through observation and experimentation.
- The theory of evolution meets the criteria of a scientific theory. In contrast, creation "science" is neither self-examining nor investigatory. Creation "science" is not considered a legitimate science, but a form of religious advocacy. This position is established by legal precedence (Webster v. New Lenox School district #122, 917 F. 2d 1004).
Biology instructors of Portland Community College will teach the theory of evolution not as absolute truth but as the most widely accepted scientific theory on the diversity of life. We, the Biology Subject Area Curriculum Committee at Portland Community College, therefore stand with such organization as the National Association of Biology Teachers in opposing the inclusion of pseudo-sciences in our science curricula.
Intended Outcomes for the course
Upon successful completion students should be able to:
A. Relate an understanding of the basic principles of microbiology to personal health and use this understanding to make informed personal and professional decisions.
B. Use an understanding of the impact of microbes on human cultures around the world both historically and in the present day to evaluate current social health issues.
C. Use scientific methods to quantitatively describe microbial characteristics and processes and understand their relationship to the identification of microbial species.
D. Use an understanding of research and laboratory experiences to organize, evaluate, and present data and information to illustrate and articulate basic microbiology concepts.
Outcome Assessment Strategies
- Essay, short answer and multiple choice exams
- Recording of laboratory experiences in a laboratory notebook
- Research paper(s) on microbial topics, library skills and presentations
- Demonstration of basic laboratory skills, including interpretation of experimental results.
