Purpose: This study examines hospital schools within Korean children’s specialized public medical centers, focusing on the interaction between educational environments and healing environments. Methods: A qualitative case analysis was conducted across major hospital schools, categorizing practices into four domains: learning continuity, daily life maintenance, social relationship formation, and living convenience for educational living environments, and natural factor, psychological stability, hygiene and safety, and social healing for healing environments. Results: Hospital schools ensure learning continuity through ICT infrastructure, remote classes, and small classroom operations, which connect to natural factors; maintain daily life through play, rest, and cultural/creative activity spaces, fostering psychological stability; promote social relationships via peer interaction areas, family participation programs, and counseling rooms, which connect to hygiene and safety; and guarantee living convenience through barrier-free design, emergency responsiveness, and accessibility, contributing to social healing. Healing and educational living environments interact synergistically, reinforcing each other to support children’s emotional stability, social development, and safe learning during treatment. Implications: The findings show the need for integrated design strategies with EBD that combine healing and educational functions.
