I think with any kind of situation between a student and teacher, they should try to get it resolved without getting too many people involved. If they can't settle it between them, they shouldn't get other teachers involved but instead go to the administrator. Then the adminitrator should hear them both out and make a professional decision about how to handle the matter.
If the issue is minor, then probably the response of most teachers will be to listen to the student and try to calm any anger that may exist. If the issue is very serious and there seems absolutely no doubt that the teacher is wrong (for instance, that the teacher has been acting in morally inappropriate ways toward the student and that the student can prove this), then the teacher should report the matter to higher-ups.
I have to agree with the above posts. A problem between a student and a teacher most likely comes about if they do not see eye-to-eye on a specific issue. Other times, a clash of personalities exists. Regardless, a teacher normally seeks out advice of other teachers to find out suggestions, not for taking of sides.
In my experience, it highly depends on the school and the administration as to whether the teacher or the student will be the most supported. A good administrator will listen to both sides and make an informed decision, using a guidance counselor and/or parents if necessary.
I have to admit, I also tend to think that a good administrator will support his teachers no matter what. I understand that teachers make mistakes (just turn on the news). That said, the prominence of student disrespect in public schools today constantly puts teachers at a disadvantage. I realize there are times when the student is on the "right side" and the teacher is not. However, most often, I believe students see things much more narrowly, and more often than not, even when they believe they are right, are wrong. As a teacher, I always take the side of the teacher first, and give my collegue the benefit of the doubt over the word of a student. I'm sorry if it isn't what you want to hear, but I think it is likely most often true.
I would hope that other teachers will not "take sides" with either party. A "problem between a teacher and a student" that happened in a classroom would mean that other teachers were not witnesses and therefore would not have all the information needed to be able to objectively evaluate the situation. There are an infinite number of variables that could impact the "problem." Without knowing all the circumstances, there is no way anyone else could assess which is the "correct side."
As the previous post suggests, the best option for other teachers, as for administrators, parents, friends, and so forth, is to act as a sounding board or intermediary while the two persons directly involved work out the solution to the problem for themselves..
sorry i did not notice
