Anywho, yesterday we spent 3 hours exploring Second Life. The students found it interesting but frustrating because they wouldn't be able to use it with their students (Yes, we discussed the Teen Grid.)
One of my students, Sara, was motivated to search for virtual worlds for kids. She used a wonderful photo of cats and sought 9 virtual worlds. Unfortunately, she only found 7 (quite a task at that) and is still looking for another 2 to complete her list.
I would suggest that she include the Penguin Club. It basically provides students with a place to hang out virtually. It is free unless you want some additional options. The membership is $6/month.
Can you find some more virtual worlds for her? If so, go to her site and add them as comments.
Go read about Sara's Sighs.
If you want some great reading, read our blogs. My students are practicing educators, IT administrators, office managers and even have a school custodian. They are an amazing group with wonderful visions of what can can be made possible in education through technology.
