Screencast videos are another web 2.0 service.  It can help you communicate with more clarity and impact than you can with written words alone. Popular uses in education include:
- Recording procedures and answering frequently asked questions.
 
- Giving students audio-visual feedback.
 
- Recording lessons that students can access anytime, anywhere.
 
- Making a video to help your guest teacher and students if you have to miss class.
 
I created a screencast video "My Case Web 2.0".
