If schools had a large amount of resources or didn&#x27;t need to scale efficiently they wouldn&#x27;t need the structure and if they didn&#x27;t need the structure children (and staff) wouldn&#x27;t become dependent on it.<p>That said there certainly are people that need structure to learn (particularly what they don&#x27;t want to learn). There are several disorders or disabilities that would make unstructured learning incredibly difficult or impossible.
