> "science-education-ism". My phrase - I don't know of a real one... anyone?

Ever since I first read it in "The Science of Discworld" I've called that "Lies-to-children" (https://en.wikipedia.org/wiki/Lie-to-children):

A lie-to-children (plural lies-to-children) is a simplified explanation of technical or complex subjects as a teaching method for children and laypeople.
