I work at a private school with students whom have learning differences and the majority struggling with ADD/ADHD. I have tried everything I can think of to get students to stop talking over me/ yelling/ blurting out/ and staying engaged. I am at a loss on how to get these students to listen to me. I’ve tried reward systems, fun games to break up instruction; differentiation; I’ve tried sternly laying down the rules; I’ve tried having private conversations with them and pep-talks. Nothing has worked. I don’t think I’m too nice and I don’t think I’m too mean. What am I doing wrong? I am open to anything.
