"The first thing that's wrong with being a science-fiction writer today is that the present has caught up with the future and surpassed it."
In the story, Margie has a mechanical teacher in her house, like every child old enough to need schooling. She must present homework in a particular form so the machine can read it and grade her work.
Punch cards or tape have been in use for a long time; the Hollerith 1890 census tabulator is a famous example. Most students today are familiar with the Scantron system, which combines machine-readable test papers with a reader/tabulator. I don't know how old mechanical test grading is.
