Mr Jones Is Concerned About One of His Students, Todd

Mr. Jones is concerned about one of his students, Todd, who has recently been identified as having a conduct disorder. Which one of the following is a good strategy for Mr. Jones to use with Todd?

A) Mr. Jones avoids talking to Todd about his problems. That's what the school psychologist is for, and besides, Todd might become too reliant on Mr. Jones for help.
B) Because Todd exhibits defiant behavior, Mr. Jones takes every opportunity to exert his own authority in the classroom. It's the only way he can keep control of the situation and not lose face with the other students.
C) Mr. Jones sets limits on Todd's behavior. "Under no circumstances will either physical or verbal aggression be acceptable in my classroom," he tells Todd.
D) Mr. Jones encourages his other students to avoid interacting with Todd in order to reduce the number of fights Todd gets into in the classroom.
