The use of a "token helper" in the management of classroom behavior problems and in teacher training.

A grade-four class teacher was trained in the use of token and verbal reinforcement by an experienced "token helper", who demonstrated the procedures in the classroom. The introduction of a simple token system resulted in significant decreases in the disruptive behavior of 10 pupils in two morning periods. When the token helper withdrew from the classroom, the teacher managed the token system and maintained disruptive behavior at lower than baseline levels.
