Don’t shout at us
The teachers who screamed at my class when I was 11 are the ones I still can’t form any kind of relationship with. Respect isn’t about having 30 silent faces shouted into submission. If you treat us as humans, know what you’re talking about and take an interest in what we have to say, you will gain our respect. Thinking of your lessons spontaneously and spending an hour shouting at us for our “disrespect” won’t get you anywhere.
