LA HARBOR COLLEGE Student Learning Outcomes (SLOs) Assessment Report Course Assessment Division: Science, Family and Consumer Studies Discipline/Program: Microbiology Course Number and Name: MICRO 020 General Microbiology Program Contact Person: Randy Wade Phone: x4558 Reviewed by: Elena Reigadas, SLO Assessment Coordinator Date: May 28, 2014 Attach additional pages as necessary. After discussion with the LAHC SLO Coordinator, it was decided to reduce the number of SLOs for Micro 20 from 10 to 6 (5 Lecture-based SLOs and 1 Laboratory-based SLO). This reduction was based on identifying redundancy in several of the original SLOs. Institutional Learning Outcomes 1 Course Intended Outcomes 1. Identify historical persons and events in microbiology and how they contribute to modern applications of microbiology. Means of Assessment and Criteria for Success Means: 5 common embedded multiple choice questions administered in 2 sections of Microbiology 20 Lecture. Summary of Data Collected Spring 2016: Criterion: a random sample of 25% of the students will score 70% or better on the assessment. 2 2. Compare and contrast the structural and functional features of prokaryotic cells, eukaryotic cells, and viruses. Means: Students will Fall 2014: complete a worksheet listing at least 5 similarities and differences between the cell types. Worksheet will be administered in 2 sections of Microbiology 20 Lecture. Use of Results 2 1 3. Demonstrate the process of transcription and translation and identify how changes in DNA sequence may affect the organism. 4. Distinguish between the mechanisms and effectiveness of natural vs. artificial means of protecting humans from pathogenic microbes. Criterion: a random sample of 25% of the students will accurately list at least 3 similarities and differences on the worksheet. Means: Students will be given a worksheet with a DNA sequence to transcribe and translate both prior to and after a DNA mutation. Worksheet will be administered in 2 sections of Microbiology 20 Lecture. Criterion: a random sample of 25% of the students will accurately transcribe and translate the given sequence of DNA prior to and after the mutation. Means: 5 common embedded multiple choice questions. Exam will be administered in 2 sections of Microbiology 20 Lecture. Criterion: a random sample of 25% of the students will score 70% or better on the assessment. Spring 2015: Spring 2013: A random sample of assessments (sample size = 50) were scored. The random sample of assessments had an average score of 74.4% on the assessment. Plans for Future Assessment Based on Results: This result was an improvement from the first administration of the assessment, but could be improved in future assessment (target 80% or better average score) by development of collaborative activities to enhance student comprehension of the topics. 3 2 5. Use current literature sources to describe the epidemiology and pathogenicity of different microbial diseases 6. LABORATORY ASSESSMENT: Determine the identity of an “unknown” bacterial sample using classic microbiology skills such as microscope use, aseptic technique and differential tests. Means: Students will write a 1-2 page essay describing the epidemiology and pathogenicity of a given microbe. Essay will be administered in 2 sections of Microbiology 20 Lecture. Criterion: a random sample of 25% of the students will score 70% or better on the assessment. Means: Students will work in pairs to identify 2 different “unknown” bacterial samples in the laboratory. Project will be administered in 5 sections of Microbiology 20 Laboratory. Criterion: a random sample of 25% of the students will score 70% or better on the “unknown” bacteria laboratory project. Fall 2012: A random sample of assessments (sample size = 50) were scored. The random sample of assessments had an average score of 95.2% on the assessment. Plans for Future Assessment Based on Results: Spring 2014: A random sample of assessments (sample size = 50) were scored. The random sample of assessments had an average score of 96.0% on the assessment. Plans for Future Assessment Based on Results: Continue to use the exercise in future classes to reinforce concepts learned in class and practice writing and research skills.
