Interventions are common tools used by school psychologists for the benefit of students and teachers. Tootling is an intervention that combines the idea of tattling and "tooting your own horn," and promotes peer-monitoring of prosocial behaviors instead of antisocial or disruptive behaviors (Skinner, Cashwell, & Skinner, 2000). This study examines the effectiveness of tootling as an intervention for classroom management and reinforcement of behaviors in regards to decreasing antisocial and disruptive behavior, increasing prosocial behaviors, and increasing academic engagement of third-grade students.
