Schooling in the 80s was still very much training us to sit still and follow the routine. Because we were all going to be happy worker bees for a living. And our classes had 30+ kids and one teacher for most of elementary school.
I’m not sure it has really changed much in most of America, especially since standardized testing became the norm and led to “teaching to the test” in many classroooms. I have since realized I had a couple teachers along the way who encouraged questioning your preconceived notions, 7 and 8 grade jr high science teachers specifically, and a metal shop teacher who they eliminated the year I would have taken it in exchange for a computer based “synergy” class.
