This site claims to be the largest student arts gallery on the web! Looks fascinating. Not sure how they use first names and locations and get away with it. I'd like to know what those who have used it think about it.
An excellent project for 4th - 6th grade sudents from Jennifer Wagner called the Prince Caspian project which will allow teachers to collaborate with other teachers around the world about the book and the upcoming movie "Prince caspian."
A great way to get started with technology is to join in an exciting project. this project by Susan Silverman was designed using the principles of Universal Design for Learning. I've heard her present and she is a pro. (Along with my friend Jennifer Wagner.)
Think.com's safety lesson with nets standards. Think.com is excellent to use with younger students and is very walled and has an excellent profanity filter. I highly recommend it and have personally used it for a summer blogging project. Excellent site. It also requires an extensive verification process by the participating schools.
Dean Shareski has done an outstanding job at creating a college level distance-learning course including many people around the world. See his honest reflections and statements about what his take on the class was. I applaud Dean for transparency and was very impressed with his set up and work.
