Wow, that is a fascinating link. Thanks for posting it. I am a product of elementary parochial schooling. I got paddled at home when I got an A-. There was NO fooling around in school - no head turning, no talking without raising my hand and waiting for acknowledgement. No child left those classes without acquiring great manners. There's something fantastic to be said for that kind of education IMHO. Public school was a joke in comparison.
I was a product of parochial and private parochial schools but they had their own books and strong discipline based on Christian faith and they had religious sisters teaching as a vocation not for a paycheck. It's all different now but the old texts or recompilations of the old work books are available for homeschooling. Most teachers in the parochial system now don't even know that according to the Catechism and the Magisterial teachings of the Vatican that the parents are the primary educators, most have never read the Catechism.
Paddled for an A-? Happened with me, too. Guess that's why I maintained a 4.0 all through high school and 3.8 in college. Although calculus really was my downfall.
I spent my first four years of school in a "convent school" in Munich, Germany. Very strict and the nuns scared me to death.
My mother did the paddling, my Dad just gave me "the look". I was more afraid of that "look" than my Mom's gentle hand.
We were in Germany right after WWII for the Berlin airlift and post war reconstruction. That, in itself, was quite an education. Right or wrong, my Dad took me through some of the Nazi death camps (Auschwitz and Dachau) before they were cleaned up. It took me years to get over the nightmares. But, I believe that experience made me the very fierce patriot that I am today.
IMHO, some of our young people need the same experience.
