confused

After leaving class and giving this more thought, I think I'm confused on the assignment. Please help.

I know that I need to write a lesson plan and come up with a way for students to use blogging as part of their learning. I am also supposed to come up with some mentor blogs for examples. Then I need to actually set up the blog for my students to use.

Here is where I am confused:
Do I set up a brand new blog on blogger.com? or Do I set up a blog through my blog under members? My students are not set up with email addresses, so how do I work around that?
