Guides to Including Young Children with Disabilities in STEM Learning Opportunities. The STEM Innovation for Inclusion in Early Education Center (STEMIE) recently released two guides on including young children with disabilities in STEM learning opportunities. A Guide to Adaptations. This guide provides information on how adults can make adaptations to support the access and full participation
of young children in STEM learning opportunities. The guide focuses on environment (e.g., room set-up, equipment, how an activity is done, length of time), materials (e.g., adaptations to toys, materials, assistive technology devices), and instruction (e.g., add information, reduce steps).

A Guide to Teaching Practices. This guide shares practices used by adults (e.g., family members, practitioners) or, in some instances, by other children to help facilitate children’s participation in everyday routines, learning experiences, and activities. Using these strategies engages children in activities, maintains their interest, and provides opportunities for them to learn concepts and thinking skills that support STEM learning when using adaptations is not a sufficient support.
