I may encounter a situation where I see another student cheating on a test. I should approach the student’s teacher when no one else is around, inform the teacher about the cheating, and present any evidence I have.
I should refrain from telling the teacher about this event in front of the rest of the students because that might have serious negative effects on the student. By telling the teacher privately, I am also helping the student to become a better person. The teacher will be able to take time to talk to the student in private to explain why the act was wrong, and the student can learn appropriate ethical behavior without facing embarrassment in front of the class.
