Here’s one Bronx middle school science teacher on a reward gone wrong:

Also, one kid saved up enough paycheck points to buy a positive phone call home, which was quite an accomplishment because she is extremely chatty. So I called her mom and started raving about her daughter, but her mom kept responding with, “What are you talking about, I know she talks too much in class!” I replied that she is a little chatty, but she’s obviously very bright and she probably talks because she’s not being challenged enough (which was a bit of a stretch, but not a complete fabrication), and her mom came back with, “That’s no excuse, she knows how to behave!” So I feel really bad, because I think my “positive phone call home” ended up getting her in trouble…oops.
