I’m trying to remember if it was Arthur C. Clarke or another classic sci-fi writer who wrote about the most popular engineering classes of the future - building low tech stuff like steam engines, smelting metal, hand making items that were late 19th and early 20th century. The kids supposedly learned more about practical applications of principals that way and it was more fun that watching simulations.
It isn't mentioned in his bibliographics because it undoubtedly came from his publications in Astounding Science Fiction and it was reprinted in A Treasury of Great Science Fiction volume II
