Teachers would find their jobs easier if they had a set of positive statements to communicate classroom rules to students rather than the frequently used "Don't Rules.""Do Rules" are behavioral objectives for use in the area of classroom behaviors. They are most effective when they state exactly what is to be done in a situation. The rules are specific and concrete, for example: "Walk in the classroom and halls: run on the playground" as opposed to "Don't Run." It is also useful to provide students with several choices of appropriate behavior, and students should be encouraged to help write the rules. A list of suggestions is given for writing "Do Rules."
