Flagella and cilia movement

by Rich Johnson


Overall Rating:

4.5 stars
Content Quality: 4.5 stars
Effectiveness: 4 stars
Ease of Use: 5 stars
Reviewed: Dec 25, 2013 by Biology Editorial Board
Overview: Flagella and Cilia Movement is a good site for visualizing the concept of how the 9+2 microtubule arrangement promotes eukaryotic flagella movement. The animation is easily controlled and can be used to enhance students understanding of this complex concept.
Learning Goals: The learning goals for this animation are:
  • To explain how flagella and cilia are arranged
  • To explain how the 9+2 microtubule arrangement in a flagella and cilia produces motion
Target Student Population: The primary target population is High School, College General Ed and College Lower Division.
Prerequisite Knowledge or Skills: There are no prerequisites for this site.
Type of Material: Animation
Recommended Uses: This material would be suitable for in class demonstration or as a supplement to course material for students.
Technical Requirements: This is a Flash Animation and requires a Flash Player to view the material.

Evaluation and Observation

Content Quality

Rating: 4.5 stars
  • Animation is accurate and straightforward
  • Content is complete and discusses cilia and flagella movement specifically
  • Graphics are simplistic yet appropriate
  • Inclusion of prokaryotic flagella movement would be a nice addition

Potential Effectiveness as a Teaching Tool

Rating: 4 stars
  • Promotes conceptual understanding of flagella and cilia movement
  • Illustrates movement on both a macro and a molecular scale
  • Structure/function relationship is made more clear with this animation.
  • Provides a good visual supplement to lecture material
  • Eukaryotic specific
  • Cross sectional view of microtubule motion would enhance student understanding
  • Shows how dynein bends microtubules but not how dynein grabs and releases microtubules, which is an important aspect of movement

Ease of Use for Both Students and Faculty

Rating: 5 stars
  • material is presented in clear and easy to understand language
  • Found no defective links or major bugs
  • Animations loaded quickly and ran smoothly
  • Easy to control animation to allow for teaching points and discussion
  • Flash player requirements may make it difficult to use on a mobile device

Other Issues and Comments: None
