does anyone have any new ideas on how to reward for perfect attendance?

hello, I get many complaints about the classroom climate...cold/hot and I have no control over the thermastat. What can I do to make my students comfortable?

how many instructors feel as if they were not given enough training before having to teach a class?

when is it okay to give a student advising for dress code? should it be after after one warning? should there not be a warning?
