Now listen to part of a lecture in an education class.

(male professor)
So I used to teach a class of eight year olds, and one problem I sometimes had was getting the kids to raise their hands when they wanted to answer a question. Like lots of teachers, I had the rule that if a student wanted to answer a question, they needed to raise their hands in the air and wait till I call their name before speaking. That gave all the students a chance to participate which helped everyone get more out of the discussion.

But some kids had trouble following the rule. I remember there was one girl, Sara, who didn’t raise her hand when she wanted to answer a question. She would just called out the answer. And this was frustrating for the other children who were waiting patiently with their hands raised. So one day when Sara called out, I asked her if she knew calling out was unfair to the other students.

I said to her, “Sara, do you realize that when you call out answers, without raising your hand, you’re not being fair to the other students? You’re not giving them a chance to answer questions, too.” And I didn’t wait for her to answer. I just continued teaching the class. And after that, anytime I asked the class a question, Sara didn’t call out the answer. She raised her hand along with everyone else.
