The group feature offered in community is a perfect place to have a group of teachers come together to share and interact within a virtual classroom environment. Read this document to learn about the guidelines for groups and how to use the group feature:
Just to clarify, our site is not open to students (under 18) but I think you meant teacher students right?
If you are speaking about students in schools (under 18) I suggest a couple of sites to you. These are places where the teacher can indeed dump (or gather) all their notes, documents, assignments, notes, etc. and students can access them. It's not really a place for discussion, but that would be available in a wiki site.
My favorite is http://linoit.com
Similar sites are http://www.stixy.com
If you need a discussion area, there are lots of wiki creation sites, and one I like is http://www.wikispaces.com/site/for/teachers where you may create a wiki with some advanced features for classrooms FREE.
I know that others will add their ideas here as well, and I look forward to their contributions. I will learn something!
Adnan, I just finished an Essentials face to face PT training. I use both wikispaces and Google Sites for group collaboration and communication. I do have the teachers join the community once the training is complete, but I want to model the use of these two sites during the trainings so they can see how they would be used in their classrooms. Some districts use sites such as edline, School Fusion, etc. These are paid sites and the teachers and students alike have access to blogs, wikis, etc. As far as the community is concerned, I am starting to use it when I hold an MT training. The resources are fantastic and they are in one place, which is great. Hope this helps?
Have you experimented with any sites yet?
