So my mom works at the same school that I go to. She was in the faculty room when my AP World History teacher approached her. He told her that he took my iPad (iPads are what we use in school) because I wasn't taking notes and that I was on another application. So I was taking notes and I got all the notes from that day but I do admit on not being on the notes only ONE time during that class period. At my house the home environment in unfriendly and strict. My parents yell a lot at stupid things. So, of course, my mom decides to tell my dad and they went off on me and took my iPad and phone. They told me hurtful things. BUT get this, my brother got caught cheating on a test yesterday with his iPad, BUT OF COURSE, they did nothing, all they did was yell at him. So today my Spanish teacher decided to tell my mom that I was "fooling around on my iPad". I wasn't!!!! I swear to god I wasn't!!! I was taking the notes for the entire period!! But my mom doesn't believe me!! I have proof of the notes and she doesn't want to see them. My dad is getting home soon and she is probably going to tell him and he is going to get mad and probably not believe me. I sent an email to my AP Teacher apologizing for what happened in class yesterday. I emailed my Spanish teacher and asked him to talk to my mom to clarify that I wasn't doing anything wrong in his classroom. My parents will tell me that I'm making up excuses.
You just need to learn to stand above it. Own up to things when you are in the wrong and be the wiser one when you are right. Try not to argue or fight with the weaker one. It all comes with growth and maturity. First steps you did well by apologising to your teacher. Try not to argue every little thing with your parents, sometimes they are right and sometimes they are wrong.... pick your battles wisely.
Trust is a lot like money. Earning it is hard, losing it is easy, and no matter how much you’re given, it may never seem to be enough.The transition to adulthood isn’t like a door that you simply walk through when you reach a certain age. It’s more like a stairway that you climb, step-by-step, throughout adolescence.The degree to which you’re accorded freedom often matches the degree to which you prove yourself trustworthy. Not that you have to be perfect. After all, everyone makes mistakes. (Ecclesiastes 7:20) Overall, though, does your pattern of behavior give your parents reason to withhold their trust?

I do think the main reason why your mom is not believing you is that you have a history of dishonesty and you broke that trust that even today it is being reflected on their actions. However, you should talk to your teacher about it because she/he was the one who is telling your mom.
Talk to them personally and explain yourself but in any case, they are really close-minded and very strict without any reason, let them you cause they are your parents. Just do the right things all the time, stop stomping and prove to them without explaining that you are well-disciplined.
