Common Core is but the most recent and furthest developed stage in the process that has been going on since WWII. It did not become critical until, perhaps the 60s in the north and far west and the 90s in those backward parts of the country that managed to hang onto the teaching of at least some of what we used to call academic subjects for a bit longer. Public Education is the reason that the country cannot return to the Republic. We do not have a population that can even conceive of what the Republic should be and once was. Restoring the Republic is the same sort of delusion that bringing orderly government to the Arabs in the middle east. Their education for many generations has been to read and memorize the Koran and to hate infidels and especially Jews with every fiber of one's being. That cannot be corrected in a population short of colonisation by a traditional Western power and a century of control of the whole system of education as with the British colonisation of India.
You are absolutely CLUELESS re the history of and historical facts about the education system and syllabus of this nation!
Right after WWII, yes, there was a "new math" introduced ( well, that "new" method was, in N.Y. State ), but though my parents and grandparents didn't "get it", it was how my great grandmother ( who yes, was still alive ), had been taught math, in Hungary, in a Catholic convent school!
Though there always have been some differences in methodology and in some subject, in private, parochial, and public schools, as well as from region to region, until Madeline Murray O'Hare became won at the SCOTUS, in 1963, the Bible was still being used in schools of ALL types and at ALL levels, as was the teaching and instilling American factual history and PRIDE, until the 1970s!
Even though there were CARD CARRYING, STINKING COMMIES, in all levels of education, they weren't the norm or even all that public about their positions, and it was EXTREMELY rare, for those teachers to propagandize students.
Now that you've been educated....please try to keep to facts , stop hyperventilating, and refrain from posting unalloyed. crap
