Might one or two students upset a positive school culture? Maybe. This session will explore the characteristics and needs of students who need secondary and tertiary behavioral support to successfully learn and contribute positively to classroom and schoolwide culture. We will explore the nature of behavior, reasons that give rise to significant emotional and behavior problems, schoolwide and classroom approaches to management, and mitigation of effects on students overall. In a follow up session on November 9, we will apply behavioral principles to problem solving and case studies.
