There are many stories of teachers touching the heart of a teen and turning his life around. However, this is a dangerous way to parent. Unless the teen is receptive to the lesson, the lesson will not be learned. Teens don't want their values coming from their teachers. They want them coming from their parents.
Studies show that it is still the parent who has the greatest influence on teens.
Teachers should only be reinforcing what the parent has already taught. Discipline must also come from the parents. One of the greatest challenges our schools face today is that parents expect the schools to raise their children. This is probably the primary reason schools are not successful. They have taken over the role of parent because many parents have decided they are too busy to bother.
