Quorum Sensing



Overall Rating:

4.5 stars
Content Quality: 4.5 stars
Effectiveness: 4.25 stars
Ease of Use: 4.75 stars
Reviewed: Dec 25, 2013 by Biology Editorial Board
Overview: This is a two to three minute You Tube animation reviewing the concept of microbial quorum sensing. The animation is narrated and is highlighted by the appearance of key terms during various steps of the process depicted.
Learning Goals:
  • Explain what quorum sensing is
  • Explain how gram + and gram – preform this sensing
  • Explain the type of signaling and what the bacteria do in response to the signal
Target Student Population: Students who would benefit from this animation include AP Biology or Chemistry students at the high school level and General Biology, General Chemistry or General Microbiology students at the college level.
Prerequisite Knowledge or Skills: A basic understanding of cell structure and what is meant by gram + or gram - is required to fully understand this animation.
Type of Material: This is a stand alone animation with voice-over functionality.
Recommended Uses: This animation would be useful as an introduction to the topic of quorum sensing. It is very short and provides a basic background of a very complex topic. Instructors can then decide how much detail they wish to expand to once the animation is viewed.
Technical Requirements: none

Evaluation and Observation

Content Quality

Rating: 4.5 stars
  • Great animation; simple explanation
  • Explains the communication of bacteria very well
  • Shows how the protein provides intra cellular signaling to DNA
  • Briefly explains G-proteins
  • Probably should view after the genetics chapter

Potential Effectiveness as a Teaching Tool

Rating: 4.25 stars
  • The simplicity of this animation makes it very useful for the introduction of this topic in a course
  • Could be used in class or as an out of class assignment or review
  • Content level makes it inappropriate for advanced students
  • Addition of a quiz would enhance the animation

Ease of Use for Both Students and Faculty

Rating: 4.75 stars
  • Easy to navigate
  • Simple to use
  • Not ADA compliant-- there need to be subtitles for the voice over narration

Other Issues and Comments: Good video. Great concept to take something this difficult to understand and make it easy.
