  I will try to be calm, understand why this behavior has been shown, try to accept the student and to talk to her after the class and if the attitude was unacceptable, 

 i will Use humor to diffuse the situation– . By asking him smartly, \"If you are a smart student, you will know through my teaching method.\"
or
Kill them with kindness
I am going to say , “…The experience has nothing to do with the quality of education and you will know this as you grow up as a teacher or work elsewhere

i take it easy , and i will answer him scientifically for give him a lesson that he should respect the other 

 I might give a silly answer to thisquestion. In general I don\'t try all that hard to keep too much of My teaching experience (it\'s really not interesting enough), but I don\'t want to be the center of attention. My students are there to learn the material, not to learn if my old enough to teach this class?My teaching experience. If sharing a little information with them helps develop rapport and establish a positive classroom atmosphere, then I\'m happy to do it. Beyond that, we really need to get back to the material.
