Slingblade:
Perhaps I'm wrong here, but it seems to me your mentors are doing just what they're supposed to be doing. They help you with stuff like start time and schedules, which is nice, but leave you to deal with difficult students on your own since that's just what you're supposed to be learning to do.
I don't think they're trying to hurt you at all, just to teach you. (By the way, how do you call someone who teaches a student teacher? A student teacher's teacher?)
Again I could be wrong.

They're called "mentor teachers."
First, you're only getting my side of things. My account is obviously biased, though I'm trying to tell what I think happened, the best I can.
Second, student teaching is part of my education. I paid a full semester's tuition for this experience. I'm still being taught how to teach. Telling me to guess at things I don't yet know isn't the most effective way to teach me anything. Everyone is different, however. Maybe such a method would work for you. But it doesn't work for me, and I'm paying for this. I'd like my teachers to use effective methods from which I can learn, since it's my money and my career, not theirs. If guessing is all that's needed, why should I even have a mentor?
Since I began receiving solid strategies both here and there, my teaching and my confidence has improved. At first, this was so hard, I wanted only to quit, and only my student loans were keeping me there. Naturally, I hated it all.
Now, after only a week of real help from several sources, I'm enjoying this and hoping I can get hired soon. I want to do this for as long as I am able to do it.
What teachers do is too serious a matter to leave to mere rookie guesswork, IMO.
YMMV.
ETA: I didn't think they were necessarily trying to hurt me, either....though some days, I did wonder....
