This site offers a wealth of information and many great resources for teachers interested in using digital media for storytelling and other activities. There are a number of very good, clear, screencast tutorials for teachers to use. Preview a few to see if you might be able to use them with your classes. I thought they were great for high school students, and they inspired me to think about creating my own screencasts for other tutorials! :-)

You can record what you do on your computer screen, add sound, choose the area you want to record from your screen and share it with the world. There is nothing to download and it works for PCs and MACs. Great for sharing tutorials.
