A couple of days ago, I stumbled across an interesting Yahoo! application that makes it easy for teachers to "create and share classroom projects that meet state standards. Yahoo! for Teachers makes it easy for you to find and connect with other colleagues around the country".
Right now, this offering is in Beta, but, if you are a teacher (and can get to the web site..which can be blocked by your schools firewall) you can participate in the Beta and provide valuable feedback to Yahoo! for improvement.
Anyway, if you can get to this web site.....give it a look.
Here is the YouTube version of the introduction video.
To me, it looks very interesting. But I'm concerned that the video is a year old and this is still in Beta. I will dig more to find out the status...
