Answer:
You should be strong, and be sure about what you want to say. Make sure when you speak it is clear, and makes sense.
Explanation:
If you don't speak up or sound like you know what you are talking about. I like to think of it as dancing. Act like you own the stage, or in your case, like you own the presentation. Also, I suggest you speak to your teacher in private, about him ignoring you. If I were you, I would look for newer friends. Ones that won't ignore you.
