This guideline from the American Psychological Association, Developing Responsible and Autonomous Learners: A Key to Motivating Students (https://www.apa.org/education/k12/learners ), suggests connections between children's and adults' creativity; i.e. adult creativity grows out of supporting children's imagination, (https://www.brighthorizons.com/family-resources/nurturing-creativity-and-imagination-for-child-development) in a supportive environment of nurturing adults. So school (among a host of influences) seems important if not crucial in supporting children's creative development, and lack of an appropriate learning environment could likely affect adult creativity negatively, supporting Robinson's talk. McClure's recommendations could be described by such a school/supportive environment.
