"Keep reading." So he kept reading and then he said "aks" again. And she stopped him again, 47:40 and she did the same humiliating thing to him a second time. And then when she said, "Keep reading," can you guess what he said? 47:49 "I don't want to read" ... because he's been humiliated about the way he uses language.
In college, I had a professor who belittled anyone who answered his questions. After the 2nd week, no one would raise their hands. It taught me to be so gentle when it comes to correcting my students when they get something wrong. If a student mispronounces something, I'll usually just insert the correct pronunciation and smile, so they can just keep going. Once you lose a student's trust, it's almost impossible to get them back in any meaningful way.
