It's been recommended to me that I start a "closed" ning site for my classroom, because our technology director refuses to open any Web 2.0 resources to students in our district, and maybe having a closed site will change that.
My question, given the attempt at classroom blogging I've already made, is how closed is a closed ning site? Last summer I prepared a classroom blog using eblogger which was blocked-unblocked-and blocked again in pretty short order. The reason for that was that in eblogger, even if your blog had all kinds of restrictions on it, the site always had that dumb "go next blog" link so students could, potentially, get to all kinds of inappropriate blogs.
So, does "closing" a ning site prevent students from leaving it to go to other random ning sites or other ning sites they may belong to that are not appropriate in the school setting?
I've tried to research this on the internet and have found surprisingly little information about it.
