MICRO20:
1) Students will successfully perform and interpret a Gram stain, compare
and contrast the structures of Gram-negative and Gram-positive cell walls,
and address why each stains differently with a Gram stain.
2) Students will apply the key concepts in the course by designing a
brochure or poster for an infectious disease or immune system disorder.
3) Students will identify an unknown bacterium using laboratory skills learned
in the course.
Assessment & Rubrics:
1. A bacterial unknown identification will scored on a scale of 1 to 3 using a rubric
addressing the following criteria: quality of the Gram stain itself, correct
interpretation of the Gram stain. A common exam question to be used in all
microbiology courses will be assessed on a scale of 1 to 5 using a rubric
addressing the following criteria: accuracy of Gram-negative and Gram-positive
cell wall structure, accuracy of Gram stain procedure, understanding the basis of
differential Gram staining.
2. A disease brochure or poster will be scored on a scale of 1 to 5 for each of the
following criteria on a rubric: description of pathogen & risk factors, mechanism of
disease, signs & symptoms, diagnosis & treatment, disease prevention, quality of
writing & presentation.
3. A bacterial unknown identification will scored on a scale of 1 to 3 using a rubric
addressing the following criteria: quality of staining and interpretation of
morphology & arrangement, determination of motility, growth characteristics,
biochemical testing, narrative and conclusions, quality of writing and
presentation.
The criteria will be analyzed based on a scale of 100% to 0%. The results of
responses to each criterion will be examined independently. The following scale
is established:
Excellent: 90-100%; Satisfactory: 70-89%; Unacceptable: <70%
