If the teacher really has the above behavior, it is obviously immoral and at fault. No matter what students are, satire and disguised satire are the teachers' fault. At this point, you don't need to blame yourself, and you don't need to be sad. It's not your fault.

"Caring for students" in the Code of Professional Ethics for Primary and Secondary School Teachers requires teachers to care for all students, respect their personality and treat them equally and fairly. Be strict with students and be their mentor. Protect students' safety, care about their health and safeguard their rights and interests. Do not be sarcastic, sarcastic or discriminate against students, and do not punish students improperly or in disguised form.

According to your sulking behavior, I feel that you should be a perverse student and know how to respect teachers. In fact, I also witnessed the phenomenon that the teacher inexplicably targeted a student. I also think this kind of thing is quite regrettable. After all, prejudice is not so easy to eliminate.

My suggestion is:

1. Be brave enough to seek the help of the class teacher or find a math teacher to make things clear. If there are some contradictions with unequal information, it may be reconciled if it is made clear; Even if it is unclear, at least the teacher will be more restrained and dare not dig at you in public.

2. If you don't want to go to the teacher for a showdown, turn this anger into motivation and try to get a good result that makes everyone speechless. But you should also realize that your efforts are not for the math teacher, but for yourself, because a teacher who violates the teacher's ethics is not worth being so angry or angry. Always keep calm and think that this teacher is just a passer-by in your life, and look forward.

Come on! Don't be discouraged by this! Study hard! Don't be angry with this teacher and fail the exam. What a pity, don't you think? Calm down and improve yourself, you can do it!
