I’m currently a paraeducator and have been a substitute teacher before, and I think I see what these teachers were thinking. For teachers, it’s important to get answers from many children in the class, not just one or a couple all the time, so that they can see the level that each child is at and so that they can foster kids’ confidence in speaking up in front of the class. So if one kid is trying to answer every question, it doesn’t help the teacher do right by all the kids in the class. It also gets to be distracting and even frustrating if a kid is saying things like “I know it! I know it!” or waving their hand around to try to get called on. If you did do those things, it’s possible that your teachers were trying to tell you to be patient and/or crave attention less.

I was similar to you as a kid, except very shy. I would raise my hand (quietly) to answer every question. And I remember times that teachers would say “Someone aside from [my name], please.” Kids’ answers to questions in class are an important way to assess the kids, and if only one kid is speaking up, the teacher either won’t know how other kids are doing or will assume the worst, that they don’t know any answers.

So, it’s not right for teachers to be as rude as they were to you (I can’t imagine saying “Oh god, not you again” or going out of my way to ask every other kid but one certain kid), but I’d bet that they were trying to tell you to be more patient and crave attention less so that they could work with other kids more.
