Play intervention is...

a practice designed to improve socio-emotional, physical, language, and cognitive development through guided interactive play. During play sessions, an interventionist uses strategies including modeling, verbal redirection, reinforcement, and indirect instruction to sustain and encourage child play activities. Through the use of appropriate play materials and the direction of the interventionist, the goal is for young children with disabilities to be better able to explore, experiment, interact, and express themselves (NCEE, April 2012).
