There are many ways that a Ning could be used in the classroom. I guess the main way that a Ning can be used is purely for communication purposes, which is fabulous! As far as educational uses of a Ning, I could see students using a Ning as a collaboration tool for group projects. Also, the teacher could set up a Ning network with students from another country and they could communicate. I feel like students would buy into a Ning because it seems like so many other social networking sites like Facebook and MySpace.
I could see it as a really awesome tool in a language class. For example, if you were a Spanish teacher, you could set up a Ning network with a Spanish-speaking country. The Spanish-speaking students could work on their English and the English-speaking students could work on their Spanish.
You can set up multiple Ning networks and students can also set them up. You have to have an email address, so that may be a downfall to using it in an elementary classroom.
Does anyone else have any ideas as to how you could use a Ning in the classroom?
