In my school most of my teachers use twitter to remind us about work and answer questions out of school hours. Do your teachers do this?

No, but I would actually love it if my teachers did that. That'd be very convenient.

They use Twitter because they're all musicians, but they dont use it remind students of work or anything

It's really convenient!

Also, because this week was our last week in school, our teachers have been taking selfies with the class and posting them on twitter

I had an American Government teacher my senior year that used Facebook and twitter to remind us of homework and stuff. I had to create a new twitter account in order to keep up. Not that it matters, since I use my twitter much more than Facebook now.

I'll be a teacher by fall 2014. I'm not deleting my account

But Twitter in the class is a neat idea, provided students and teachers both make separate profiles

I'd either not follow them or use a separate account for following teachers who post about schoolwork.

None of my teachers do, but my school library has a twitter

My cousin is a teacher, and she told me this student got suspended for talking about her on twitter.

i had like 1 teacher who had twitter but i never bothered following ha,anyway she protected her account so idk what she actually does on it.
isn't it weird and awkward if your teacher knows your twitter tho?

We're generally really friendly with our teachers in my school so no-one really thinks twice about it.

No

Of course, my teachers used to.
