Have you been in a situation where you felt you could explain something better than your teacher? What did you do?

I'm trying to ask the professor a question to draw the attention of the professor to the right information ... I think this is the best method of polite you can use with your teacher if you feel that it is wrong ..

Thank you for the invitation ..

Thank you for the invitation......

I think by the nature of the teacher if he was understanding I can discuss with him and give your opinion .. If he was not understanding I try to ask him a question to correct the information and give an opinion without feeling

I never been through this issue, but i always have students who are brilliant and explain things and give answers which are more than perfect, I usually ask these students to have the lead on doing some tasks with their friends in order to encourage other friends to be motivated.   

Yes, most of the time. I will catch his/her attention by raising my hand. First, I have to be polite showing that I am very much interested about the topic or issue then add my ideas to further explain my other point of views .Of course, I will not embarrass my professor/teacher and still thank him/her . I will see to it that my deepest respect would still be felt in the end.

Yes! I'd start with 'Did you mean...' and explain my understanding of what the teacher is trying to explain. That way, I'd be giving her an alternative way to explain the topic and at the same time I'd be benefiting my classmates (the ones who are listening as least). 

  i agree with what Mr Abdellah benomar answer , the better way to help teachers is ask him question contain the idea .
