We just learned about the UEN teacher site.  It was awesome.  My favorite part the e-media room where you can find videos of all kinds of subjects and you can download them.  Awesome!  There is so much at your finger tip.  I would use the UEN site for the e-media part.  I would love to be able to use the web can and find people not only in my state and the U.S. but also throughout the world.  Wouldn't it be great to have your students actually talk to a person in China and have them tell them about their culture.  I would also use it for my lesson plans to get information or to publish my own ideas.  There is a lot more I need to learn about this site, so I will end my writing and go explore UEN some more.
