ENHANCNG SENSORY DEVELOPMENT IN EARLY CHILDHOOD THROUGH INNOVATIVE 3D PRINTED SESNORY BOXES

Abstract

Sensory processing is one of the most critical aspects of development in early childhood as it helps in motor, language, and emotional development. This project examines the effectiveness of customized sensory bins with 3D-printed elements aimed at enhancing the sensory development of children at the Nancy W. Darden Child Development Center (NDCDC). Tailored toward developmental levels from infancy into early childhood, these sensory bins integrate tactile, visual, and auditory activities designed to foster developmental milestones. The bins are categorized into four age-specific categories: The Little Explorer’s Box (0-12 months), The Little Learner’s Box (12-24 months), The Little Discoverer’s Box (2-3 years), and The Little Imaginator’s Box (4-5 years). Materials like kinetic sand, playdough, fabric swatches, and magnetic playboards are included alongside interactive 3D-printed elements such as color-matching puzzles and imaginative toys.Produced at East Carolina University's Isley Innovation Hub, 3D-printed components provide customizable and cost-effective sensory tools. Handbooks were created for each sensory box, highlighting the developmental benefits of each toy, acting as a guide for teachers, parents, and caregivers in engaging children with the toys. The design of this project was informed by research supporting the benefits of sensory play for cognitive, motor, and social-emotional development, especially beneficial for those with developmental delays. With our backgrounds in psychology and communication sciences and disorders, we could apply the knowledge we’ve gained in child development, somatic processing, and therapeutic interventions to contribute to the design and implementation of the project. Dr. Lauren Turbeville, MSOT, OTD, OTR/L, mentored us in creating inclusive and developmentally appropriate sensory toys. Two observational visits were conducted at NDCDC to assess the bins’ effectiveness. These visits focused on children’s engagement with the materials, problem-solving abilities, and peer collaboration. The continuing feedback from teachers via survey indicates that implementing our developmental packages will foster a collaborative and hands-on learning environment. This positive impact suggests that integrating resources tailored toward a child's development will encourage deeper engagement among children and provide innovative teaching approaches. Sensory play is necessary in early childhood development, strengthening motor skills, cognitive growth, and social interaction. Customized sensory boxes with various 3D printed materials provide children with hands-on opportunities to explore, problem-solve, and connect.
