The Reggio Emilia approach to early childhood education originated in Reggio Emilia, Italy and was developed by Loris Malaguzzi. It is a child-centered educational philosophy based on constructivist learning, sociocultural theory, and experiential learning. Key principles include viewing children as capable learners who construct their own understanding through interactions with others and their environments. Adults act as facilitators who observe and support children's interests through play and open-ended projects. Documentation of children's work and conversations is also an important part of the approach.
