How can I get my teacher to take me more seriously?

Sometimes in history class, I goof up on a question, or as soon as he calls on me, I forget what I was trying to ask. Not only is this “occasionally”, but I do this quite frequently. And, I don’t do it on purpose, it just happens.

I thought about talking to my teacher, but then I feel like that’ll make matters a little awkward. I know he won’t take me seriously because he talks to me like I have a learning disability or as if I’m 5 years old. I know he may joke around, but that gets a little offensive after a while.

I know I should just try a little harder, but I work my ass off for the A that I already have. I really try to sound smart, and say my answers as thoroughly as possible. But then he’ll look at me, not comment on my answer, and then move onto the next student.

This has been bothering me for quite some time, and I don’t want to have a relationship with my teacher where he thinks I’m just a goof up in class, because I know good and well that I’m not.

How can I get more respect from my teacher?
