How do I deal with a very rude teacher?

Everybody, including teachers, should be respected. However, you do not have to deal with this type of behavior and treatment. She shouldn't be a teacher if she's gonna treat her students like that! She has to respect her students. As a teacher, I'd NEVER talk like that to my students.

Report her and talk to the principal about it. She can't keep teaching. Kids need cheerful, nice and passionate teachers. Not someone who brings them down and can't even teach to begin with.

Teachers are supposed to help you gain knowledge and understanding in a proper manner. But when that’s not the case;  continue showing respect as it states at (Rom. 12:18); “If possible, as far as it depends on you, be peaceable with all men.” The link below leads to an article on this topic of getting along with teachers; bringing out real experiences similar to yours on how they dealt with their situation. Along with another short article about coping with stress. 

Tell EVERYONE. Record the activity. You have a cell phone...USE IT. Make copies. Tell your parents. Tell the administration. Tell the school board. Do not let this kind of crap just "go"!

There is only one way to deal with this and it involves spiking your teachers coffee with LSD.

If this is only you, forget it. If others in the class feel the same as you and any of you are failing because the teacher hasn't taught you well, then a group of you should go and speak to your school counsellor, explain the situation (without a single exaggeration), and ask for advice.

You may just be told to suck it up. Maybe that really is the best thing to do. You ask how to 'deal' with this teacher. You don't 'deal'. You sit quietly, you address her politely but as little as possible, you do your homework meticulously, and you look ahead to the future when you won't be in her class any more.

I’m so sorry this is happening to you.   Even though you’re in HS, would it be possible to get your folks to go to set up a conference with the teacher, and discuss the matter?  (Be forewarned...just as you have issues with the teacher, the  teacher might have some issues with you, as well, so be prepared for HER side of the story, I suggest you start with the teacher first...see if you can get your parents involved and things resolved.  Going to the principal or school board first, would be like a neighbor getting mad at you for your noisy car...and calling your folks before talking to you.  However, if you CAN’T resolve things with the teacher, then do go to the principal.  He/she may not have a clue as to what’s going on, but needs to know!   I don’t know your school’s policy about changing teachers, but maybe it could be a last resort.  Good luck to you, and congrats on your outstanding grades!

i would talk to your principal about her

Well I would report her to the broad of teachers and also secretly record her if you can sign a fake account so it don’t get back to ya and shame her alive

You didn’t relate anything establishing that she had any part in him committing suicide.  And, I find it hard to believe when I hear this type of thing regarding a teacher.  They wouldn’t remain teaching long if their students were always failing for not understanding the material.  A few students, sure.  But, not the class, as you claim.

Honestly, I have dealt with SOOO MANY bad, mean,and unmotivated teachers. There is not much you can do unless they are physically hurting or, or extreme verbal abuse that you can take up with a counselor or principal. I am sorry you are going through this honestly. The best thing to do is just ignore them. Do you're work, stick with the good grades and just pull through it. It wont last forever, I promise. It's worse to try to talk to a person who acts like that.
