I have often felt that the one-room school was a better option for education than the big consolidated institutions we have today.
All eight of us kids went there,, we had some of the same teachers, grades 1-6 ,, How one teacher can keep 25 or more farm kids under control was no mystery. They were gentle yet firm, and some swung a nasty ruler. ;-) not that I advocate nor personally got re-attentioned.. Much
These teachers were expected to teach multiple topics, do all the testing and keep the heat on as well.. Used to be a wood coal furnace , later replaced by an oil one.
One wall was all books, it’s where I learned to read and read.
