God expects the best in everything we do. To do less is wrong, and to perpetuate mediocrity is even worse. Excellence should be the norm, not the exception. Classroom success does not come cheaply.
Some teachers are naturals.
For these teachers, teaching comes as easily as breathing. But natural teachers are the exception to the rule and not the rule. Most teachers must learn how to teach after they actually begin their teaching careers. It is true that teachers learn from their undergraduate and graduate courses, but it is experience that turns a novice teacher into an effective teacher. Teachers also learn from the professional books and magazines they read, as well as from the feedback they receive from their principals and supervisors.
