Who never raises their hands to ask/answer questions and talk?

Question

i never did on any of my classes. Is it good or bad to ask and answer questions?

i feel scared, so i never tried.

can someone tell me why teachers are so confident, and aren't embarassed to talk and speak in front of the class?

Answer 1

First it is good to ask questions in class.  In demonstrates that you are paying attention and that you actually care about what the teacher is saying.  Also it helps the teacher to see you as a person not just someone sitting there killing time.  Not to mention that you will get your questions answered and therefore have a better understanding of the topic.

As to why teachers are embarrassed to talk in front of class, its like anything else.  You do something enough you get better at it.  In addition knowledge and preparation are key to running a successful class.
