Executive Function--we hear it frequently in early childhood education but how much do we really know about it? The development of this collection of skills can be a predictor for children’s future success. But what skills are included? This PROTON provides an overview and definition of the executive function skills, including working memory, mental flexibility, and self regulation. Additionally, this element contains information about how to support the development of these critical life skills into daily classroom practice and routines. These modules contain videos and links, so headphones/speakers, a printer, a camera, and an internet connection are recommended.
