Content Quality: 3.25 stars
Effectiveness: 3.75 stars
Ease of Use: 3.75 stars
Reviewed: Dec 24, 2013 by Biology Editorial Board
Overview: The antibiotic assay tutorial provides students with background, mode of action, and uses of several classes of antibiotics, which is followed by instructions on how to calculate antibiotic concentrations in patient fluids using graph paper and how to analyze the results. This activity gives students a good hands on opportunity to apply foundational knowledge of antibiotics to a real clinical setting.
Type of Material: Tutorial
Recommended Uses:
  • Group or individual assignment that students could work on during class time or outside of class time as a way to practice applying concepts introduced in class.
Technical Requirements: Microsoft Word
Identify Major Learning Goals:
  • Students will learn how to collect, graph, and calculate antibiotic concentrations
  • Students will learn how to evaluate antibiotic concentrations and make therapeutic recommendations based on the concentrations
Target Student Population:
  • Upper level microbiology or Medical Microbiology classes
Prerequisite Knowledge or Skills:
  • Introductory Biology

Evaluation and Observation

Content Quality

Rating: 3.25 stars
  • The material is clearly laid out
  • The content integrates the concepts of antibiotic use and therapeutic indications well
  • The background material is accurate
  • Does a nice job of engaging the students with concepts
  • The answer sheet is missing. When you open the answer sheet file, it takes you to a Salmonella exercise
  • Not all links were active
  • Background information on drug mechanisms of action is probably not necessary

Potential Effectiveness as a Teaching Tool

Rating: 3.75 stars
  • Demonstrates relationships between antibiotics and therapeutic indices
  • The analysis and interpretation of data promotes problem solving
  • This is a ready-to-go assignment that can easily be carried out in class or out of class
  • Learning objectives are not stated
  • Material is basically text and images, not animation

Ease of Use for Both Students and Faculty

Rating: 3.75 stars
  • The instructions are clear and accurate
  • It is well written and easy to navigate
  • The speed of downloading is appropriate
  • The inclusion of the graphing paper is a plus
  • The error in the link to the answer sheet
  • There were several broken links at this site
