Things were so much simpler back in the days when dinosaurs roamed the earth. I was in school back then.
We had only one teacher for each grade. Everybody who was in that grade had the same teacher, same room, same everything, except maybe same desk or same girlfriend or boyfriend; we didn't share them, although sometimes they got swapped around as the year went on.
My teachers always seemed to choose me as their favorite pupil and gave me the chair nearest their desk.. grin. All the teachers must have known I was pretty smart, but they had trouble remembering my name. They kept calling me “Smart Alec.” 
Most of the time we had our own pencil, although at times we had to "borrow" one. I was mighty glad when they stopped making us use tablets and start using Sky-Hi notebook paper like the big kids.  If I remember right, that happened at the Needmore School of Higher and Lower learning when we were in eighth grade.
We didn't need an SRO officer then either. Our principal, Mr. Bilbrey, took care of any crime organized or otherwise. Although I was shot at a number of times.  Those Dishman boys were really bad about bringing rubber bands to school and shooting people with paper wads. So, of course, I went armed myself, just in case.  But, being the good child I was, I only shot in self defense. 
No criminals ever came near the school, must have been afraid the teachers would make them stay.  "Tattletell"   girls were about our biggest problem, always wanting to tell the teacher about something we had done.  I think Ms. Stella must have been a bully, because we were all afraid of her.  She didn't even allow us to run around over the room while we were having "books."   She would catch us by the ear and lift up so hard that we had to tiptoe, and march us  back to our desk and invite us to have a seat.  It's a thousand wonders I didn't end up with a warped personality, instead of just one ear longer than the other.   
Those were mighty good days and we learned whether we wanted to or not. In my humble opinion, schools would be much better off if the teachers did not have a whole bunch of red tape, no child left behinds, and races to the top, and teaching to the core removed and just let them teach students.   Now it's all about teaching for test-taking.  
I believe my generation did pretty well after graduating from our schools then.  At least three of our local students went on to work on projects to help put people in space and one became an astronaut and went into space. Our school system produced doctors, lawyers, educators, soldiers and even a few country preachers. So having prayer and saying Bible verses didn't completely ruin us as some fear today..  grin.
