The document discusses the ABC model of cognitive behavioral therapy. It provides an example of how the ABC model can be applied to analyze the behavior of a student in the classroom. The ABC model looks at the Activating Event, Beliefs about the event, and Consequences. It then provides two examples - a negative example where the teacher is unprepared and the students misbehave, and a positive example where the teacher maintains control and the students respect the teacher. The document argues that the teacher can act as a therapist in the classroom to understand problems students may have and apply techniques to improve behaviors.
