Gender is learned; it is a social construct. There is a lack of literature connecting children’s social identity formation and education for ecological sustainability in early childhood education. This gap in literature can be attributed to a common misconception that young children are not able to understand and express more complex social identity nor identify with ecological and sustainable education principles. However, this inquiry illuminates that from the perspective of Reggio-inspired educators’ social constructivist experiences, preprimary age children are in fact competent and capable of socially constructing complex knowledge and of representing their theories on identity and ecology through reuse materials.
