In the student's eyes, this type of incident is none other than practical, gut-level Christianity in action. It is a dramatization of the morning's Bible lesson and carries with it much more clout than that sterile, sedately presented lesson. Some teachers are able to win their students with love to the point the class does not want to misbehave. They know it would hurt the teacher, and they love him too much for that. Being the most powerful kind of motivator, this teacher realizes that with love she can extinguish most misconduct from ever developing in the first place.
Students learn from a teacher's sense of fair play.
If the teacher is to model discipline to his students, he must be disciplined himself. Christlikeness rings hollow when students are disciplined for being late to class by the teacher who himself is often late. A third sphere of influence is how a teacher dresses. A teacher cannot preach modesty yet signal suggestiveness. A teacher cannot preach moderation yet dress as a fashion plate.
