Challenging Behaviors in Early Childhood is the first course in a three-part series of self-paced courses designed to support early childhood teachers’ and caregivers’ understanding of the social-emotional learning and development of young children. This short course is divided into three interactive modules to help teachers 1) understand these differences; 2) identify the developmental and environmental influences that aggravate challenging behaviors and 3) find strategies for de-escalating and responding positively to challenging behaviors when they occur.
