A standard item in the classroom of the 1950’s was the clerk’s bell. A shiny nickelbell sat on the teacher’s desk. With one tap of the button on top he had everyone’s attention. Teachers have shown a lot of ingenuity over the years in making use of non-verbal cues in the classroom. Some flip light switches. Others keep clickers in their pockets.
Non-verbal cues can also be facial expressions, body posture and hand signals. Care should be given in choosing the types of cues you use in your classroom. Take time to explain what you want the students to do when you use your cues.
