This is the way I use Rock Star Word of the day: as a music teacher, I give each class a word that relates to the day's topic. For example, on the sign (laminated) I put the word "composer." When the class is too noisy especially when you are trying to teach, you take a letter. If they lose all the letters, then they are put in assigned seats. Then the class must earn the letters back in order to sit where they choose.
This could also be used with key words in a regular education class.
