This creates a positive classroom culture because it gets the students involved and invested because they came up with the word. A secret word takes the stress out of classroom management because it sets a routine expectation for the students. When they hear the word they know what to do. Involving the students in the rules and procedure making lets them know that they are important . The creation of rules and procedures is for them and their learning and letting them become a part of making rules will only reinforce that this is their classroom.
