Personally, I have strategies for when I'm sitting in class, not wanting to be called on

A teacher will ask a question and then look to find someone to call on. You know things are going down hill if he or she says "let's hear from someone we haven't heard from yet"

Don't just sit there in fear

Take action

For me, I grab my water bottle and quickly start drinking it, because they're less likely to call on you if you're occupied

A friend of mine uses the coughing method. When a teacher asks a question, she'll raise her hand, but quickly start fake-coughing. Then she'll lower her hand and keep coughing like she can't answer at the moment

And there is, of course, the classic no eye contact method. This one doesn't always work for me, it really depends on your teacher

But yes these are some options and you guys can see if they work if you want

And comment any other things you do when you're about to be called on that you find effective
