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.
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:
This material would be suitable for in class demonstration or as a supplement to course material for students.
This is a Flash Animation and requires a Flash Player to view the material.
Evaluation and Observation
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
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
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
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
