I am proud to say that I went to a one-room schoolhouse in NE Kansas.
Our Teacher, Mrs. Bell stoked the stove in winter, cleaned the room year-round, rang the bell in the belfry, produced and directed the CHRISTmas program and kept the impressive library in perfect order.
She didn’t do bathrooms, however...they were one-holers down at the edge of the school property and didn’t require much attention.
Our superintendent, Mr. Swoboda came round once every two years or so in his own car. I believe he had one clerk for the entire school district which was one county in size...
And I grew up to be a nuclear physicist.
Produced before WWII, it had everything you needed for a U.S. High School education: three European languages, Greek, Latin, Algebra, Geometry, Calculus, Trigonometry, European/U.S. History, Zoology, Botany, Chemistry, Civics—and perhaps other subjects I've forgotten. Maybe you were expected to be accomplished in English grammar before entering High School—IDK.
Oh yes...Physics... (Which started my rant!)
