Dr. Sophia D'Agostino's scholarship aims to improve meaningful inclusion for young children (birth to five years) with disabilities through socially valid practices. Early childhood inclusive education is the inclusion of children with disabilities into high-quality early childhood education programs (e.g., public or private preschool, community-based childcare, Head Start). Two primary strands of Dr. D'Agostino's research are (a) understanding and improving teacher preparation and training to increase the quality of services that children with disabilities receive within inclusive settings and (b) dissemination and use of naturalistic developmental and behavioral interventions (NDBI). NDBIs are evidence-based interventions informed by both developmental psychology and applied behavior analysis guided by an understanding of child development and implemented in the child’s natural environment. Dr. D'Agostino's intervention research focuses on the use of telehealth or training and coaching at a distance using technology. Further, social validity is central to Dr. D'Agostino's research. The use of NDBIs and telehealth for training and coaching emphasize social validity which is integral to implementation fidelity, generalization, and maintenance of practices within early childhood inclusive education programs.
