This past Thursday, my physics teacher got really angry due to me and another friend not being in class when we should have been. She said that she would be late to class and will enter at 8 am (Class starts at 7.45). She asked us to be in class at 7.45 and have given us work to do. Me and a friend were not in class at 7.45 as we were doing our work in the common area and decided to go to class right before 8. Around 7.54, she texted me asking where were we and i replied that we were doing our work in the common area and are going to class now. She said that we were supposed to be in class and that we do not need to come to class already for that day. Basically, she has taken that we have escaped class.
After the class was over, i went to see her and talked to her about it. She was really angry and said that me and my friend will have to sit at one side of the class as she does not want to see us anymore. The rest of the class will sit on the other side and she will only focus on them. She said that we have no respect for her and the class. It was only a one time thing and it was not like we were escaping her class (There are different ways to look at it). We just thought that she was really stressed out as she was part of the exam section and they was a lot of things going on and that she would be better on Saturday.
So Saturday, we went to class and she asked us to sit at one side as she had said already. The class went on as normal but just with her not paying attention to us. After she was done with the work she had planned for the day. She showed a 3 page pdf file about me and my friend on the projector. It was about us being late to class from time to time and having no respect for her and the class and much more. There were also new rules we had to follow now that we were cast aside in the class such as not being allowed to speak to anyone when we are still in the lab. She then said that we will not write our university references for us two and if we insist on her writing, she will just mention our academic capability in the subject (physics) and then mention about how our character is (Late, 'escaping class', no respect for her and the class). As a matter of fact, she is the teacher i feel that i relate the most to and respect.
As my goal is to study engineering or physics at university, a good reference in physics is definitely needed as i want to apply to the top universities especially Imperial College London. If i do say so myself, i am quite a capable student and being cast aside in class will not affect my academic performance much. Even she herself said that I could achieve a credit easily and its just a matter if how high i want to push my grade up. How would i try to convince her to write the reference for me?
TLDR; Teacher got angry due to us not being in class at the time she wanted us to. She now says that she will not be writing our university reference. How would i try to convince her to write the reference for me?
