Greg is a seventh-grade student classified with an emotional behavioral disorder. He attends general education classes with consultative support from a special education teacher and behavioral specialist, Mr. Biggs. Although school just started a month ago, several general education teachers have reported that Greg's demeanor in their classes is excessively disruptive. Which of the following is the most appropriate way for Mr. Biggs to address the concerns of Greg's general education teachers?

While positive reinforcement can be effective, this option lacks specificity and does not address the underlying disruptive behaviors directly. Simply rewarding days without complaints may not provide the structure or clarity necessary for Greg to understand which specific behaviors need to change.

A response-cost token system could potentially reduce disruptive behaviors, but it may not be the most appropriate initial step. This approach focuses on consequences rather than understanding the root causes of Greg's behavior and does not involve collaboration with the teachers to identify specific targets for intervention.

While obtaining parental consent for a full evaluation is important, it may not be the immediate step needed to address the current disruption in the classroom. This process can be time-consuming and may delay necessary interventions that could be more effectively implemented through direct collaboration with the teachers.
