My advice to you. * If you are teaching adolescents; Don't get worked up over them laughing about you stuttering. I recommend you make jokes as much as possible and be as funny as you can. Then if they ever talk about you, your stutter wont be the main thing they talk about and you wont have much to worry about. * If it's just kids, they don't really notice once they can go home to their parents afterwards, so you shouldn't have much of a problem there. * If you are teaching in a college or to adults, then when you go into the classroom, just say straight off "I have a stutter, so If I pause at all, that's the reason" *Most* adults will be understanding and shouldn't be too pushed about it. If you don't tell them, they will most likely think something else of you. I hope this helps and I hope everything goes well for you, your stutter should never hold you back.
