Questions, questions, questions, etc. Jack and Ryan call out “all the time”—when they have answers to questions, when they have questions, when they have information they want to share with Ms. Andrews or their classmates. Ms. Andrews has been told they have “poor impulse control.” She decides to reinforce them for raising their hands. Each time either of them raises his hand, she immediately calls on him and provides verbal praise. Within 2 days both boys have reduced their callouts to less than one a day. Two days later Ms. Andrews is satisfied that the boys have learned to raise their hands, so she goes back to her usual procedure of randomly calling on students who have their hands up. Two days after that, the two boys’ calling out is back to its original rate.
