Public school teachers are responsible for their students' academic achievement. Their primary role is to deliver academic material in a structured and safe learning environment. One thing that hinders their ability to execute this, however, is having to intervene on behaviors that interfere with optimal learning. These interfering behaviors, known as challenging behaviors, may include calling out, wandering, protesting, and off-task behaviors. While these behaviors are not unsafe, when they go unmanaged, the delivery of academic instruction is impacted. Knowing how to effectively manage these behaviors has been the root of stress among educators. Teachers receive explicit training on how to create and deliver academic instruction while pursuing their degree; what is missing, however, is explicit evidence-based training on how to effectively manage challenging behaviors in the classroom using evidence-based techniques. The current project sought to address this need by evaluating the use of computer-based direct instruction, an evidence-based teaching method, to train teachers how to implement an evidence-based classroom management system known as the Good Behavior Game (GBG). After completing an online training that utilized direct instruction, the teachers implemented the GBG with a group of confederate students. This was followed by the delivery of specific performance-based feedback. Teachers then reimplemented the GBG until specific mastery criteria were met. Results indicated that the computer-based direct instruction was effective in increasing all teachers' ability to implement the GBG, but that performance-based feedback was a necessary component to meet mastery criteria. The benefits of using computer-based direct instruction paired with performance-based feedback will be discussed, as well as directions for future research in supporting the use of effective teacher training modalities.
