Should you defend your quality?

You might find, if you describe your training and qualifications to your students, that you might just interest one or two in taking up teaching as a career. Just a thought.

Your qualifications are not your students' affair. You will not waste class time arguing.

Tell them to take any questions to the school administration/school board who have hired you, who have renewed your contract, and who sign your paychecks..

you mean if i tell them about all my experience as a teacher and translator
etc. that they might be interested in such a career? i guess, maybe that is true, the students who are happy with the way i am and when they see how much i enjoy teaching, they may think about it , it is true

I agree with Noddy! Questioning your credentials is not something a
student is equipped to challenge. If the majority of your students aren't
in agreement with the quality of your teaching, they should take their
concern to the school authorities.

I simply would ignore their provocations, or have a short sufficient answer along these lines: "I would not be here if my credentials weren't impeccable" Then go on with your curriculum.

man, why am i so stupid that such simple, realistic solutions don't occur to me? it seems i will have to rely on kind and patient members of this forum forever - of course, if the students have doubts, they should check with the administration - but the fact that they haven't - probably - only shows that
those are some teenage rants and whines

you know how i learned about such comments? a student from univesity showed up, working on her thesis and gave my students some forms asking
all about literature and reading as a part of EFL - for some reason, i have no clue why, she included this question or point - write the good and bad sides of your English teacher

now some students had this silly idea that they will turn her forms into a farce - later they apologized for that cuz they ruined her work
and filled out things like this about me, here are some examples:

Pros: Handsome
Cons: He has never studied abroad

Pros: Buddhist
Cons: Buddhist

PRos: Tall
Cons: sometimes talks bullshit

Pros: He really cares about us
Cons He doesn't know English

Pros: None
Cons: Self - taught


So who knows what was just fun and what they really meant, but where the heck did they get some of the information, I don't know
Obviously, they had no idea that I would ever get to read the forms. One of the students, having just realized that I have read the comments came to me and apologized for all of them, which was nice, but still, I was and still am bit worried about what kind of reputation do I have? And why?
Especially about that "self-taught". Like I have never studied at university?
And the most puzzling is "He doesn't know English." I mean I probably don't know English because that sentence doesn't make much sense to me. In Czech we don't always say He speaks English. We also use "know English". Maybe that was just a joke. Maybe the student thinks that I should know all English words that have been recorded in all kinds of dictionaries.
